Helpful video! What happens, if you have more than five outliers? in the table at the end, it only shows the 5 highest outliers... How do I find out what the other outliers are?

Hey! This was SO helpfull, thank you!! I have a few questions. I am studying the effect of SES, IQ, school achievement, and teacher expectations on academic self concept. I have missing data in all my independent variables. So do i have to make a 'missing data' variable for all of them? And than use these in my mediation analysis? Thanks!

@Michelle Hollenbaugh Hi Michelle! Nice video🙂 I wish to know how to calculate the reliability of a questionnaire in spss if we have missing data in some questions? Is it using the usual cronbach alpha?? And what should be putten in the cells of the missing data in spss?

I noticed that when you recoded rincom91 into a different variable rincom91_md and changed old values of "system or user-missing" to 0 and all other values to 1 that the values of 0 in rincom91 were recoded as 0. But should they not be a 1? It is not a missing value in the same way an empty cell is. What if 0 IS an answer of that participant's rincom91? Would that not affect the things done later?

@eduardoplarr 4 жыл бұрын

Hi, when you check that the difference is significant you were actually checking the P value for the Levene's test for equality of variance. Shouldn't you be looking at the p value for mean differences?

Thank you for this great video. I have a couple of questions. 1) What if we have more than 20% of the data for one variable missing? 2) What if all missing data are from one case. Drop it from analysis? And 3) What if the results of t-tests come back statistically significant? Thanks!

OK, that was fantastic!! I couldn't even expect it to be so complicated when my supervisor asked me to use the sample mean for the missing answers! Just one question if I may, I have a few respondents who haven't answered 1 question out of the 3 or for that there are in the questionnaire. Is it advisable to follow the procedure you described or shall I remove them completely?

@bizanjo 6 жыл бұрын

Thank you very much for uploading this video. While identifying multivariate outliers I could not understand how did you calculate the critical value in this example (you mentioned its 24.3) ?

@michellehollenbaugh941 6 жыл бұрын

Hi! so you need to look this critical value up in a chart of the chi square distribution. this is often in the back of statistics text books. I just googled and found this one online: www.medcalc.org/manual/chi-square-table.php So you use the number of variables you are analyzing as your degrees of freedom. in this, we used 7. then look at the p=.001 column under 7 degrees of freedom, and you will see that is how we came to our critical value of 24.3. I hope that helps!

hi! i love this tutorial and it really helped me out so thank you! but question, if for example, my mean is 2.93, do i round up so it'll be 3 or do i just take the 2 to use as my missing variable? thanks!

@michellehollenbaugh941 6 жыл бұрын

Hi Katrina! Thanks! This would be based on your judgement- I personally would probably round up to 3, but I think you also need to consider your variable, and what the difference between a '2' and a '3' is on your measure; and how that relates to your sample. I hope that helps!

@mengguojing8943 7 жыл бұрын

Thanks for the very clear and informative tutorial! One question, could you explain why we do the Bonferroni correction by dividing 0.05 by 2?

@michellehollenbaugh941 6 жыл бұрын

Sure, since we are running two post-tests, we have to correct for the added type 1 error that might occur when running more that one test. So while we would usually say that anything with p=/<.05 would be statistically significant, we would count for the possible error with two tests by dividing .05 by 2, and looking for anything with p =/<.03 and considering that statistically significant.
