Is it valid to use the mean and standard deviation from a similar, but not exactly the same, study to estimate the sample size for a retrospective study? For example, the reference study was done in patients with diabetes, but the retrospective research will be done in patients who had a stroke.
Nicely demonstrated Ma'am! How can we calculate sample size through this software for survey research where we have only one sample to collect? please explain.
Thank you for this video. It is very helpful. I am doing a study in which I am using PLS (using SmartPLS software) analysis. My research model has 3 independent variables, 2 mediating variables, and 1 dependent variable. Can I use G*power in this case to do power analysis? My sample size is 160. I need to show that power is not an issue with this sample size.
normality test for paired samples, many colleges place pretest and posttest values and giving to sign values while others place differences between pretest and posttest giving one sign value, what is the true???
is it enough if l have 60participants for experimental and 60 participants for controo group?

Excellent
Thank you
Ma'am what effect size I can take for research in social science related to HR topic
thank you ma'am
Thank you🙏

Very nice mam,
Mam. I m new to research field. How should I continue, which book I should refer.plz help me out.

excellent presentation and very easy to understand...Mam plz guide me how I will find sample size for three groups...
My research design is RCT
How to calculate Ttest in smartPLS?
Mam agar hum survey krrhe aur hmari population 1000 h to sample size kya hogi hmari
Please refer to my video when population know how to calculate sample size
