Quantitative Research Designs: Descriptive non-experimental, Quasi-experimental or Experimental?

[@chandadove5670]

You just saved me from dropping out of school. Thank you.

[@zanelesiyengo9646]

Lol, hahaha. I know the feeling. Good luck

[@carlskraastad1792]

lol This is part of my required class prep for grad school.

[@sarasaz5221]

I rarely comment on KZbin videos, but this was worth commenting on - thank you so much for simplifying it. My head has been spinning trying to get round this subject - again thank you :)

[@kwikwit28]

Thank you! Thank you! Thank you! I learned more in 6 minutes and 37 seconds than I did in hours of reading textbooks.

[@aunahmed231]

But she made the 6 min 37 sec video after reading text books!

[@voxnihili7097]

I spent days trying to understand these concepts and because of you, I finally understand! I know it is frowned up[on in the research world, but youtube is the best source for finding information on any topic.

[@wonger5]

you simplified in 6 minutes what my text made very confusing over 20 pages! Thank you

[@NurseKillam]

You are welcome. That's what I try to do - simplify complicated things. :)

[@12119LY]

So right!

[@noobbsaiboot]

you are truly amazing. People like you deserve to get paid for your skill to simplify things. You just save me.

[@floverfloverflover]

omg life saver, i have been struggling for a few hours to identify what research design this one research is, and 1min into this video, i finally got it.... thank you

[@TheShanahg]

I am in accounting research class, having problem with research design, thanks to your video I now understand a lot better!!! Thank you!

[@NurseKillam]

+Benjamin Hanggai I am so happy it helped.

[@Apricorn62]

My professor recommends your video for our class, and it was extremely helpful! Thank you :)

[@NurseKillam]

+P CARRETE awesome to hear!

[@breepanuco6155]

@@NurseKillam Me too! thank you!

[@adahajdari]

You need to write the research book.!!!!The reason why everyone finds research difficult its because the books are written by someone who know research well not taking in consideration others like us who have no clue. Thank you for sharing your teaching expertise.

[@drsheikh]

The coolness with which you explained the concepts. I wished you were my teacher at school!

[@NurseKillam]

I am a teacher ... I hope I'm cool in person too :)

[@djokoviclover3152]

Please could you help me

[@alleychampagne7671]

Thank you so much!!!! my peers and I continue to look forward to your videos every week!!!

[@daphyneshine3222]

This was SO helpful. I knew the heart of my research design but I didn't really know how to approach the description for the methodology of my design. I couldn't distinguish between correlational or causal-comparative or not. After watching this, I know my particular design is neither of those. THANKS!!

[@NurseKillam]

+Daphyne Shine awesome! I hope you figured out what it is as well :)

[@slcascarano]

Thank you for the clarity. This link was key in helping me grasp the subtle differences in quantitative research study designs.

[@akcross44]

OMG!! AMAZING FLOW CHART! you truly go above and beyond. so helpful!! like extremely helpful!

[@SMHo-zb2mi]

NurseKillam, you are the best online tutor. As a matter of fact, my professor has 2 doctorial degrees and he is not as clear and direct as your teaching. Are you really a NURSE??

[@NurseKillam]

Yes, I'm a registered nurse with a masters degree. I also happen to teach. I'm happy you like my videos.

[@SMHo-zb2mi]

Why come a nurse would become a Stat teacher? Kind of curious. Do you know anything about SPSS too? Would you mind posting video about that?

[@NurseKillam]

I teach research, but not stats in depth. Research is part of the undergraduate nursing curriculum. I don't know SPSS. When we need that we consult a statistician :)

[@nomadsworlds8404]

Goodness, this video is very detail,now I can proceed with my paper.Thank you NurseKillman.I believe that you should give my professor a refresher course.

[@NurseKillam]

I'm happy you found it useful :)

[@aryansaeedi7618]

Omg made life easier thank you so much. And you have a beautiful voice. Very easy 😫😫 I wish you were my teacher

[@amirabile6338]

Designing my own research for the first time and I must say working out the study design, the size of the sample, statistical power, choosing the right measurements and so on can be daunting! I found your video very helpful although I am still unsure of what to call my study?! :D

[@NurseKillam]

It's true it can be hard to think through everything but it is such an important step. Have you tried talking to some experienced researchers near you? Are you in school? If so your thesis supervisor can help. If not, try making friends with someone at a university that is interested in the same thing you are. Sometimes just talking it through helps.

[@amirabile6338]

I am in my second year of psychology at university. You are right, by talking to others I about it helped a lot so I started to network.

[@gabriellekardon7227]

I found your video very easy to follow and informative. The flowchart is useful, easy to follow and provided the clarification I needed. Thank you

[@setred1970]

Thanks so much for simplifying a subject that has been challenging me for the last several weeks. I wish I would have found you sooner but think I can now address my professors questions with much more intelligence and insight.

[@NurseKillam]

That is so awesome to hear. Thanks for the feedback. Knowing that the videos are useful is what keeps me making more :)

[@prof.julsonetienne3181]

This is too informative. A+ I just notice one thing. Instead of controlled, you wrote down "COMTROLLED"(5:57) . Guess what? That did not stop me from getting the information needed. I considered it just as a typographical error.

[@abdurahmaanhaaji6310]

Thnk you dr.Killam really you are such a great lecturer. You have showed me the right and easiest way to clasify research designs.

[@kransey1]

Thank you for the clear, concise video. VERY helpful to a novice researcher!

[@mariep7718]

Thanks so much for breaking it down so well for the rest of us to understand it :)

[@ChiTwnCutie]

Super simple and the visuals were great!! I am ready for my comp exam! Thanks!

[@brittanylanier4513]

This was perfect explanation for help with my final project. Thank you!

[@NurseKillam]

You are welcome!

[@sethamule]

This video was amazing and helped to make Research not so confusing! I even shared this with my research class. Thanks so much!!!

[@NurseKillam]

+Seth Mule Awesome!

[@karenelizabethmitchell-kee1058]

So wonderful to see you. I am stuck and this is very helpful.

[@chefelsitabella9750]

Thanks you so much.. I don't want to drop my class this is so difficult to understand and you made it so simple. 🙌👏 Keep up the video. I will like and subscribe.

[@justinenyangaresi4174]

Good presentation. You made everything that has been hard to me easier

[@muhammadsalim5777]

Thank you so much for your short but very effective video. I am really benefited. As I have an exam. it will be helpful for me.

[@NurseKillam]

I'm happy it helped. I hope the exam went well.

[@tcgunntcg]

You took terms that seem so complex and simplified it. Thanks!

[@alienspacebat5218]

My current teacher and the textbook she uses told me information that contradicts this video. According to them, for a study to be experimental it is only necessary that assignment to the experimental or control group, not sampling, be random.

[@NurseKillam]

+Eufinity she is right. What I talked about is ideal but if I did this video again I'd make that clear. Thanks for pointing it out. I don't know if I can do anything to this particular video to clarify that but I will try.

[@jenniferturner6339]

Oh thank you so much!!! I was SOOO confused!!!

[@MrJajang01]

Dear, NurseKillam . Very awesome video. May I use it for my students who are learning about research methods? best regard, Rif'at

[@NurseKillam]

Yes, please use my videos any time you want to. Laura

[@mohammedakhtar5604]

Its really helpful for me. Thanks for giving such precious information. Keep it up.

[@kheyseed]

Thanks, it is very brief and clear. I will use this for the introduction of quantitative research in my class. I hope you wouldn't mine.

[@saimenaraurme5609]

I am so glad that I have found you. The article that I am critiquing uses a prospective cohort study, there are no intervention. Before terming the quantitative method as non-experimental descriptive, how do you know its descriptive? Hope to hear from you soon.

[@NurseKillam]

Basically if there is no intervention it is descriptive. If the researchers didn't DO anything to participants - like give them drugs or education or a new treatment of some kind.

[@nadjlab604]

So helpful. Why cant they teach it like this. SMH So helpful for my assignment.

[@yamikakapitao2340]

Thank you very much for the clear explanation. I do rarely comment but I couldn't hold myself . Excellent

[@sonneblom733]

Thank you for this information. What type of data collection can I use for if colour code charts work in hospitals?

[@karinekentenyants7625]

Excellent description!

[@melaniedrew1097]

What about correlational? Thank you for your video?

[@emmanuellaadzaho1032]

This was really helpful. Thank you

[@nivekanderson1149]

So helpful! Is a questionnaire considered an intervention? Thank you for your assistance.

[@heregod]

I wish you were my research professor , YOU would make me love research :D

[@monahousen-reynolds428]

Hey @Nursekillam love your vids, they are very helpful. Could you tell me how to figure out the population in a study if it was 3 trained research assistants watching videos of 2 TV shows to mine for data for a quantitative study. Would the TV shows be the population, or is there no population? I'm so confused.

[@NurseKillam]

Are they trying to generalize findings to the TV shows? If so that would be the population. I'm thinking they may be watching them to generalize findings to the people who watch them. It's hard to say without seeing the question.

[@shoelace19]

Our teacher is having us identify which statistical test to use based on Research Question scenarios. Happen to have a video on how to identify terms to clue us in on which stats hypothesis test to apply. i.e. One Sample T-test, Two Sample t-test, z-tests, Two-way Anova, Chi-square Goodness of fit, etc...?

[@NurseKillam]

Not yet but I can look into that once I've adjusted to life with my new baby. Unfortunately it won't be in time for your class. If you find any good resources please let me know as I'm curious about that. I suppose you are likely going to need to identify the level of measurement and number of relationships you are examining to figure that out. I do have a video on levels of measurement. There is a good table in one of the textbooks I have that would help. See if yours has one.

[@AnnaHartmanPR]

see SPSS survival manual by Pallant. Her chapter 'choosing the right statistic' is ch 10 in the 5th edition.

[@molhamsa8575]

Among the best videos Thanks really!

[@dilansenevirathne4125]

this is very useful video described in simple manner... how can we access to other videos...??? pls send the links

+Dilan Seneviratne If you click on my name/picture it will take you to my channel where you can find all my videos. kzbin.info

[@andreadoc123]

I love the video. I would like for you to make a video on how do you support your study relationship based on a theoretical or conceptual framework.

[@NurseKillam]

Excellent video idea! There are a few ways to do that. I'll add this video to my list ... Probably for October. Thanks for the idea and for subscribing!

[@pionking3538]

NurseKillam I also love the video and have subscribed. I would love to see the see the October video on how to support study relationship based based on ones theoretical framework.

[@NurseKillam]

Thank you! I am just editing a video about nursing diagnoses and I will start working on that one :)

[@NurseKillam]

I am working on this video next. When you ask about the study relationship are you asking about the question or results?

[@manishbharati985]

Hello,Your video was extremely helpful. I am doing some research on alcohol consumption in pregrnancy in relation to post partum depression, in this case I want to do purposeful sampling and divide the mothers who consume alcohol in one group and who donot consume alcohol in other group. I think ramdom sampling cannot be done here. However, I want to put both the groups under same test giving equal chance with same intervention to find co relation. So, is this a quasi experiemental design or not ? If not then what is my research design. Please advice me soon if you have time. Thank you

[@NurseKillam]

+Manish Bharati You are right that random sampling would likely not be possible. Can you randomize to groups in this case? It depends on the ethics of the intervention. I can try to help but I don't feel I have enough information to understand the study proposal. If you want to do an experimental study your sample is likely going to be a convenience one rather than a purposeful one.

[@jenniferdrew6119]

Hi. I'm trying to determine what a research design would be in this situation: whether an online tutorial had any effect on the number of questions asked about A (a specific event). Basically, looking at statistics of questions asked about A before and after the tutorial was made available online. There really isn't a control or experimental group per se, as we are just looking at statistics.

[@jenniferdrew6119]

+Jennifer Drew An intervention was made (the tutorial) but we didn't specifically give it to the participants.

[@NurseKillam]

So Quasi experimental. You have an intervention but no control group.

[@kaumudeemanodara8507]

In my experiment, units are selected in random and there is no control group.It is pre-post experiment and my pre observation act as a control group.can i categorized as quasi experiment. what is the best sample size fro such experiment which would use non parametric method? Useful flow chart and thank you for best explanation.

[@MonikaWoodstraveler]

typeo at 6:03 - comtrolled - should be controlled?

[@macscully3980]

Hello, I am in a graduate course examining the difference between research and evaluation, and wanted to ask for your thoughts on what the differences are, but also what similarities both might have. Thank you.

[@imanebelhoucine8657]

thanks for the simple explanation

[@christopherallenpeer753]

Excellent video, way to simplify it all.

[@NurseKillam]

Thank you

[@marienmartinez8008]

THANK YOU soooooo much for clarifying this research "french" for me.....

[@NurseKillam]

You are welcome ... Most of my students call it Chinese ;)

[@Adam-jo3tr]

Great video! You described the concepts really well. Thank you!

[@AlaaHamza-b6e]

Qusi experiment should have control group?

[@kimdlawson07]

Thanks for the videos. I teach online and I often post your videos (with citation of course). Do you have any videos about spss software?

[@NurseKillam]

I am happy you like them. No, I do not have any on SPSS. I can't do that kind any time soon (I don't even have SPSS ... When I need it I ask a statistician for help).

[@mihretumenamo275]

Now I am Applying It! Thanks Sis......

[@ccstrawberry08]

Thank you for sharing this video. It was a big help! I have a couple of questions though... Is it convenience sampling in a school setting where the researcher has to get permission for students to participate in the study when only a few students give permission to participate? If it is convenience sampling and students are randomly assigned to groups does that make the study experimental or quasi experimental? Thanks for your help.

[@NurseKillam]

+Hello-Kitty08 What you described sounds like convenience sampling. There is a difference between random sampling and randomization. Random assignment to groups is what differentiates a true experiment from a quazi-experiment. You can have a RCT with a convenience sample (although you would critique that it decreases generalizability).

[@pietrobeglari6374]

Hi Nurse, would you please explain about quantitative correlation and its related research question? What is the difference between correlational and Quasi-experimental?Sofia-PhD Student

[@NurseKillam]

Correlations are a technique used to answer the research question. A correlational study is a type of study. Quasi-experimental is a class for non-experimental research that may include a correlational study. See 9:49 in this video kzbin.info/www/bejne/i3KTXoWDhc5qp6c

[@kieranchamberlain6329]

This has been of great help! Thank you.

[@NurseKillam]

You are welcome :)

[@ezerjardinico494]

Hey guys. Supposing you cannot apply a true experimental research design but you still want to follow a quantitative research design, what research can you do?

[@NurseKillam]

A quaziexperimental or descriptive study depending on the context.
