I have never commented on a youtube video before, but I just needed to tell you how much you have just saved my stats. I have spent countless hours in the last week trying to figure out how to convert my standardized residuals to a p value that I can compare to my bonferroni adjusted p value. this was amazing.
Dr. Grande, I wish I had seen this video when I was taking Statistics in undergrad! This would have been so beneficial for me to watch and use as a guideline while initially learning this information or as a refresher later in the semester! Overall, I found this video to be fascinating and helpful. Likewise, I really appreciated the way that everything was broken down step-by-step.
This video was helpful in helping me realize the importance of using a post hoc to test for probability and significance. If my research proposal was extended into a study, I could se myself using post hoc.
Thanks for your awesome tip for chi-square post-hoc test. I have a question. The degrees of freedom for the chi-square are calculated using the following formula: df = (r-1)(c-1) where r is the number of rows and c is the number of columns. When you put CHISQ.DIST.RT function on excel, degree of freedom value should be (3-1)*(3-1), I guess. Thanks for your video again.
Thanks a lot Todd, I just have one question, How do I interpret this finding? do I say that ''Individual learning method'' was significantly more effective than "Group" and "Online" in producing Low outcome?
Excellent vid; thx. Similar question as a few others have posted: How do I interpret this finding? Did Individual learning method produce significantly fewer Low outcomes?
Hi, what does it mean when on first impression i.e. from the cross tabs result you get a significant difference but then after completing the post hoc test they all show significance?
I teach biostatistics to head students and appreciate your channel greatly. Thank you. Question, is it not that the adjusted standard residual is a Z-score? If yes, can't I use it to calculate a P-value using the NORM.S.DIST excel function? And would squaring a Z-score turn it into a Chi-stat, hence what you did in the video?
Hi I really want to know if I use fisher freeman Hilton instead of test of independent can I still use post hoc test to define which pair is significant?
Hi, may I ask a question? I followed your steps and calculate the p value of each cell. May I know how to interpret the results? If the p value is less than 0.05, can I say in this row, this column is significantly different from other columns? Looking for your reply, Thanks
Hello, thank you for the extremely useful video. My question is that why "df" equals to 1 in the function of SIGNIFICANCE(ChiSQ, df)?

thanks for the detailed video. please add interpretion for your results of post hoc...

Hello Dr Grande, I just want to thank you for this video. It has been enomrously helpful and I am very grateful. Keep up the good work, kind sir!
Why did you put df=1 in =CHISQ.DIST.RT(x.Deg_freedom)? the Degree of freedom in your Chi-Square Tests is 4. So why put 1? Thanks in advance
Same question

Thank you for your explanation. I highly appreciate
I'd appreciate if if you could demonstrate how to obtain cramer's v values for each pairwise comparision. Thank you.
What is the difference between bonferoni correction option and this procedure
Does anyone know how to write the results up?
How did you determine to use 1 as the degrees of freedom when converting the z scores to p values with the chi square.dist.rt function in excel?
Yes, shouldn't the df be 8?
the comparison is between the expected value of each box with that of observed value, hence df is 1
Thanks!
Should it always be 1?

Hello, Dr Grande. Thank you for this very useful explanation. Does this post hoc test have any specific name?
Very helpful. Thanks.
You're welcome - thanks for watching -

follwoing that
Why adjusted standardized residuals instead of standardized residuals? How do you get these in excel?
How can we calculate the effect size in this post hoc test?
Is there a citation for this method?
I'm looking for a citation too? Any luck finding one?\
thanks dr. grande
Thanks boo :)
