[@saramotalebi24]

Thank you for teaching this so well.. i really needed explanation for my project.

[@aesthetique496]

thank you so much. i searched for days how to do this test and finally found your video

[@michellewilcox8769]

As a kinesthetic learner, I cannot thank you enough for breaking down these data analysis methods! I was able to follow along with this demo and work my dataset using SPSS software. Thanks again for bringing my textbook to life!

Thank you Muli.

Thank you sir! this really helped me understand T test.

[@ekpenyongudofia9459]

this is an excellent video on comparison tests

[@hajarzakzouk7458]

Very good explanation.. I have a question if you please, if I have an independent variable containing only two groups how can I get the subset for them ?

[@drfalakseharsahito9683]

Excellent description. Thanks

How to denote significant difference in multiple comparision. Such as codeing a, b,ab, c,abc .

[@RESEARCHHUB]

you will need to do ANOVA post-hoc tests, see kzbin.info/www/bejne/qpTEcn2OabKFo9k

Hi, I want to compare the lipid levels taken at different time points for 3 times, i.e. individual patient with blood test taken three times at random dates. How can I compare the mean change of each lipid level for intervention 1 vs intervention 2? Please help me. I am very confused.

[@worldofinformation815]

Thank you Sir

[@nazmulhassan197]

Thanks for the demonstration. How can i compare a test mean in more than 3 times taken

[@RESEARCHHUB]

One factor repeated ANOVA or Friedman test. see kzbin.info/www/bejne/b168Z6p_gt14rqs

[@mehrunnisakhan7356]

if we have comparison of public and private teachers then the sample of i took is 75 then the data entry is double 75 for public and 75 for private or just 75 data entries should be made for comparison of t-test

[@RESEARCHHUB]

Do you have data from 75 public and 75 private teachers? In total 150?

[@chayandas-p1i]

When there is more than 2 category like ses or race then what we need to do?

[@Dr.MomRocks]

No matter what analysis I do in SPSS, no significance is reported. I don't know if I have my data in correctly though. I have 7 groups of participants, 25 questions in my survey, and I want to see if there's a difference in the means for each of the questions for each group. What do I do?

[@mathildearctander]

How do you do anova when there is 9 independent variables and 1 dependent variable in the analysis?

[@RESEARCHHUB]

In that case, you should consider a regression model. See kzbin.info/www/bejne/l36uhp6kqMdkZ8U and kzbin.info/www/bejne/n2nXm3-HirWWbrs

[@hudaahmed9496]

Hi sir, please can you interpret the mean difference for me? I am struggling to understand its meaning, and it was a little rushed in the video. thank you

[@sputnijk]

amazing!

[@calvinchao1134]

How can I compare means between two groups with more than two dependent variables? Should I just run multiple independent T-test?

[@KCM1]

omg thank you

[@alirafati2995]

Hello there. I have a situation. I have two variables that are numeric and scale. I want to compare these two to see if they are having the same pattern or not in increasing or decreasing during the time (during 10 years that the years are the rows of my dataset). Can you help me with that? Which analysis can I use in SPSS fo this?

[@RESEARCHHUB]

you need to run correlation, see kzbin.info/www/bejne/bH6ppZ6CntSNbLs

[@nanic3692]

I'm trying to run a test using a variable, and spss tells me that I can not use "String Variables" . What can I do? Is there any email that I can contact you for help? in my project?

[@lilyhart7099]

I had this issue too w my project and changed my variable to a numeric variable. You can see if it’s a string variable if you go into variable view. I think it should be the second row. I’m no expert but I hope this helps!

[@syedsadaqatshah1044]

You didn't tell us about the method of two different groups, if they are statistically different.

[@Junie0911]

thank you for this great video. Would you mind help me with this question regarding the Independent samples t-test which has driven me nuts recently? Let's say I want to compare the income (IC) between male and female; and the component income consists of various types of income (IC1, IC2, IC3). Is it possible to compare IC with cumulated means of IC1, IC2 and IC3 (using independent t-test)? The video only mentions how to compare means of each items. Thank you very much.

[@RESEARCHHUB]

Yes, you can calculate (as a new variable, say 'IC') the average (or some form of aggregate score) of IC1, IC2, IC3 using the compute function in SPSS (under 'Transform' tab). Then, run t-test on the newly calculated variable IC for mean comparisons between male and female.

chi-square test many be used, see kzbin.info/www/bejne/mpSui2R8oaqcmrM

[@aifoonaahammed129]

Don't we want to test the normality before performing a t test? In both one sample, independent samples cases..

[@RESEARCHHUB]

yes, that is a recommended. see how to check normality at kzbin.info/www/bejne/epnchKGGd5aUnLM

[@akromnasirov5158]

Please may I leave a question here regarding to Anova test ?

[@RESEARCHHUB]

Sure. What is it?

[@rashin3111]

What if gender has 3 category in independent samples t-test

[@RESEARCHHUB]

does all categories have enough observations? if one category has 2 or 3 observations, it will not provide any meaningful results. If sample conditions are fulfilled, proceed with ANOVA for 03 categories.

[@timf6969]

please use 1 for males and 2 for females - very confusing when using 0 as a variable

[@RESEARCHHUB]

Hi, I recommend using 1 and 0. Otherwise, later, you will have to convert the "2" to "0" incase you run a dummy variable regression.

[@timf6969]

@@RESEARCHHUB but most scripting tools use 1 and 2, they never use 0 as a variable

[@RESEARCHHUB]

@@timf6969 May this is how we learn new things, that is, coding dichotomous variables using 1 and 0 helps us using them in dummy variable regression setting without any further transformation!
