Hi Sir, Just want to know how to calculate standard deviation for the sample data. I want to find out the standard deviation, so that i can plug the value in sampling error formula to determine the sampling error..
I assume that population size is unknown/ infinite, therefore I plan to use Cochrane Formula- which gives a sample size of 384, for this study, at 95% confidence interval, 50% degree of variability, 5% as margin of error. All my questions are on Likert 5 point scale (Interval data). Is that appropriate to be used?.
Thank you for the helpful video. For G*Power please share if dimensions of variable are counted as separate predictors? Like I have 3 IVs (IV1 has 8 dimensions, IV2 has 3 dimensions, IV3 has 5 dimensions), 1 Mediator and 1 dependant variable. Total Predictors will be 4 or 17 or any other number?
SIR, If i want to compare three groups, then Daniel soper calculator gives me the minimum sample size "required for each group" OR "minimum sample size required altogether"?
@@researchwithfawad I have read this paper. It also does not specify whether sample size given by g power is for complete data required, or for the groups. And this study has taken effect size of .25, but medium effect size is .15. This study also does not mention the number of predictors taken for the model.
Greetings sir I have two questionnaire 43 statements and 25 statements respectively And in both I got sample of 490 and 320 sample respectively Is my sample good enough ?

Please use Descriptive statistics in SPSS

Yes, it is appropriate.
I appreciated your clarity of concept
Thanks. I am glad you liked it.

Only if analyzing dimensions separately.
If dimensions are not analyzed separately in hypotheses, do not consider them as separate predictors.
@researchwithfawad thank you sir for clarity, JazakAllah.

Could you produce two staged of PLS-ANN tutorial, particularly how the R-squared for ANN is calculated
Sure, when i work on it.
Greetings sir
I have two questionnaire 43 statements and 25 statements respectively
And in both I got sample of 490 and 320 sample respectively
Is my sample good enough ?
Please watch the video
hello, please the link of the study. thank you
Reference is in the description; please put it in Google Scholar.
OH YES THX@@researchwithfawad
website to calculate sample size??
