[@imanejai6953]

No one has ever explained SPSS as you did, you're a life saver

[@TheConceptsbyDrAtifBilal]

Thank you.

[@shamcaster6087]

I was going crazy trying to understand this whole thing and this explained everything Thank you sir

[@oladunni3134]

A very good and straight forward explanation...Thank you sir

[@j-lmilesdorado2403]

Thank soooo much sir.. A lot of help for my thesis..

[@TheConceptsbyDrAtifBilal]

Good to know that.

[@thurainhtet]

Thank you from Myanmar. This video is life saver for me

[@TheConceptsbyDrAtifBilal]

Good to hear that ☺️

[@sountasticmind5072]

Very good explanation. much oblidged. keep up the good work

[@jalan2dibelanda]

Hi Sir. Thank you for the clear explanation! I got this in my basic statistics class,,,but it was 2 semesters ago,,,en even w my notes I still get confused sometimes. Yet your SPSS series is really2 a life savor! I'm more confident doing my analysis now. :)

[@TheConceptsbyDrAtifBilal]

I am Happy it is helpful.

[@jalan2dibelanda]

@@TheConceptsbyDrAtifBilal I have a question Sir. Let's say I just want to use 2 variables from this data set. I want to make a methodelogical note in my syntax. The books I read teaches how to filter cases but..or merge data (merge data, from Predictive HR Analytics book by Edwards&Edwards, page50-52: Data=> Merge Files=> Add Variables => select a data set to merge w the active data set) => Continue => then I can select the variables and click Paste so this step will be noted in my Syntax. But, let's say I want to make a new data from your data set (so not merging). For example, my friends and I do a project together, we share it on qualtrics. But my individual report does not discuss/include the 1st variable (eg. F1 to F7 of your data set here). So... I do not want to include the 1st variable (your 7 items), how to do that without deleting 7 columns manually? Apologize for asking, but I've checked on youtube as well..I didn't actually find a complete answer to this. I came as far as understanding filter case..

[@TheConceptsbyDrAtifBilal]

@@jalan2dibelanda As long as I understood your question, I think you can copy-paste the data in other columns and deal with it or make new sheet of SPSS or Excel for a new data set.

[@jalan2dibelanda]

@@TheConceptsbyDrAtifBilal Thank you for the reply Sir! I have just finished with collecting my data. Now I have been trying to analyze my results. I used Qualtrics to distribute the questions Sir. I have a question...I had to do factor analysis Sir before checking Cronbach’s alpha. I had like 40 questions. En 20 of them measuring a latent variable: HR practices. Using direct oblimin en eigenvalue 1, I had 4 components Sir above eigenvalue of 1. My lecturer said force it into 1 factor. My question is...does it mean I should tick "Fixed number factor" and type 1? I did that, though I was not sure if that was right. The KMO is marvelous en significant. Then 1 item out of 20 is below .30 ...so I should delete that particular question right? I'm not really sure whether I'm doing this correctly or not. Hopefully you could enlight me. Thank you Sir!🙏

Dear Dr. Atif Belal, Very well explained. Congratulations.

[@TheConceptsbyDrAtifBilal]

Thank you

[@user-qh9kp2sh8i]

Nice way to make me understand understand

[@TheConceptsbyDrAtifBilal]

Glad to hear that

You are the best! thank you so much!

[@sultanali-gc2gd]

Thank you for explaining

[@samiraben1217]

Thanks a lot for this informative video!

[@tharindunithamodya590]

How can i analyze the effectiveness of formative assessments as one of the research questions through doing an close ended questionnaire? Can i use to test Cronbach Alpha to analyze it?

[@hoorikivibes]

you are a life saver thank you sir

[@TheConceptsbyDrAtifBilal]

Happy to help

[@PratibhaNagtilak]

Sir, you are explaining SPSS is a very easy way. Thanks. I tried using the same set of variables with fewer cases. On doing reliability analysis, I got negative alpha. Pasting the message. Please suggest how to resolve this. Reliability Statistics Cronbach's Alphaa -.240, N of Items 7. The value is negative due to a negative average covariance among items. This violates reliability model assumptions. You may want to check item codings.

[@matsonmainza7902]

Excellent

[@TheConceptsbyDrAtifBilal]

Thank you so much 😀

[@JuLy-be3jh]

Thank you so much.

[@gerarda.t.isaiah8128]

Thank you sir for this lecture, how do I improve a reliability scale that is below 0.5

[@TheConceptsbyDrAtifBilal]

There is an option of if the item is deleted, u can use that. I have explained it in the video.

[@canafacan1969]

Thank you for the video! I have created a multiple choice test with single correct answer to measure my students' knowledge of English idioms. In terms of reliability, is it enough for me to conduct cronbach's alpha ?

[@TheConceptsbyDrAtifBilal]

You do not need to check reliability. Just take the frequency and see the results. Or run cross tabs for more detailed results.

[@pacificsharks7120]

Rare video a big thanks to you sir

Thank you.

What analysis can we use to assess the validity of a survey before it’s administered to participants?

Hi Dr Atif, thank you so much for this video. Based on your table on Cronbach Alpha, 0.6 - 0.7 means questionable. After testing the reliability, I got 1 independent variable with a Cronbach's Alpha of 0.613 (Cronbach's alpha, if the item is deleted, is showing 0.662, 0.708, 0.314 and 0.343) whereas another 1 independent variable with a Cronbach's Alpha of 0.684 (Cronbach's alpha if the item is deleted is showing 0.662, 0.612, 0.693 and 0.473). What should I do? Does that mean these 2 independent variables' questions (4 questions for each variable) are questionable/non-reliable? Does that mean I have to state "Rejected" in my reliability testing for both independent variables? Please advise. Thank you.

[@TheConceptsbyDrAtifBilal]

See if you can increase the sample size. Sometimes the alpha improves with that. Other option is to delete an item to improve it. Otherwise, no worries, anything above 0.6 is also acceptable according to some researchers. When you are writing an interpretation of reliability give a reference of Umer Sakaran's book.

[@mlyeo]

Thank you, Dr Atif.

[@khadijamarvi1033]

Please send demographics percentage frequency

You are welcome

[@ritasaqeb1744]

You just save my life 🫠 Thank you 🙏

[@TheConceptsbyDrAtifBilal]

Thank you

[@user-iw5xr5ew3f]

Sir if the whole analysis is done with all the items but reliability of one scale is low so can we just state that if two items are removed then the reliability becomes higher? Also sir Perry, R. H., Charlotte, B., Isabella, M., & Bob, C. (2004) state that .50 to.70 show moderate reliability. Please advise according to all this information and what best way we should go forward.

[@TheConceptsbyDrAtifBilal]

If you have a reference then no need to remove items.

[@user-iw5xr5ew3f]

Ok sir thank you 🙏🏼

[@ifraiqbal9566]

Can you please tell me how can I find the reliability of subscles?

[@TheConceptsbyDrAtifBilal]

The same method. Just use less items.

[@wajeehatahir6364]

when ever i check for Cronbach alpha i get Fleiss Multirater Kappa outcome instead. how can i fix it?

[@TheConceptsbyDrAtifBilal]

Just before clicking ok on the window, check which option is selected... Alpha option should be checked in..

[@shwetarai5715]

hello sir, I have watched your videos to check reliability and validity. i manually calculated the composite reliability and it is above 0.99 for 2 variable. is it okay? because i read somewhere values greater than 0.95 are also not considered ideal. Pls reply i really need help. Thanks & regards

[@TheConceptsbyDrAtifBilal]

This looks too high to some people and they think the data is fabricated.

[@chotabhim4814]

Assalamualaikum Atif sir, i couldn't find Cronbach alpha more than.63 for any variables. If items deleted it couldn't improve also. What changes can help to find Cronbach apha more than 0.7

[@TheConceptsbyDrAtifBilal]

Removing items or increasing the sample size can improve it.

[@khadijamarvi1033]

Sir for the reliability test there is no need for computing first ?

[@TheConceptsbyDrAtifBilal]

Yes, no need.

[@anamtara5533]

My job satisfaction scale has 6 time and I have 600 data and the realbilty is 0.642 it's fine or not

[@TheConceptsbyDrAtifBilal]

It is acceptable, but it will give you problems with factor loadings, as it is not very high.

[@htikeeiaung1295]

Thank you❤❤❤

[@bernardakosahasiedu4333]

hello Dr. Atif. I am getting a negative cronbach alpha and what does it mean?

[@TheConceptsbyDrAtifBilal]

The data is in bad shape

Thank you very much

Welcome.

Sir could you kindly share me your previous video link of factor analysis on g drive

I had deleted it, but there is a clear hint about what you are looking for.

Sir then kindly share.

Sir I have. 637 how can I make it in 7 kindly tell me procedure how can I correct my data
