What if we are using 2 questionnairies that use different scales like one from 0 to 4 and another one from 0 to 7 ? What should we do before analyzing composites from both questionnairies?
@@MohamedBenhimaPhD how do you do that? Also, I’m trying to categorise my knowledge variable into good, fair and poor knowledge. I’ve tried computing the total and recoded it into a different variable. Then I ran the descriptive analysis but didn’t get the table I was looking for.
@@MohamedBenhimaPhD I sincerely disagree with you when you say ANOVA can be used for two groups. You can only use ANOVA when the groups are more than two and essentially when the equal variances are assumed across the three or more groups. I will share more details with you if you insist.

Thxx for the valuable video🙏
Most welcome
Hello sir, how to find t-value of each item in item analysis. If any video related kindly share
can we apply two sample t test on this type of data and also anova on this because there is no normality condition sir
Thank you sir.
Can we first transform to compute mean of likert scale and then perform one way anova test?
Hey, did you do that?
great
What spreadsheet/analytical tool are you using?
SPSS and Excel
@MohamedBenhimaPhD thanks for the quick response 👍🏾
@@stephanieawuah most welcome
is it possible to put all likert scale questions in one table?
Yes
@@MohamedBenhimaPhD how do you do that? Also, I’m trying to categorise my knowledge variable into good, fair and poor knowledge. I’ve tried computing the total and recoded it into a different variable. Then I ran the descriptive analysis but didn’t get the table I was looking for.
Hi, I have tried these but is does not work. Mine bring the codes in the output instead of the labelling. then it does not allow me do Descriptive.
I think I get it now. I uploaded the coded values from my questionnaire and it worked.
Please why did you do ANOVA using a grouping variable (Gender) that has only two levels (M or F)?
ANOVA can be used as well with two groups. Gender can contain (prefer not to say group)

@@bartholomewdesmond1826 Yes only more than two groups, but not always the case. Sometimes, ANOVA is used for gender with two groups.
thank you
Thanks a lot.
Welcome
I doubt using mean here with likert scale
Yes, the mean has thresholds for interpretation due to the existence of neutral options
