Cronbach's alpha and correlation

Postby Guest » Sat Mar 07, 2020 4:56 am

Hi guys,

I've got this problem in my statisctics class at uni and I really don't know how to solve it. I study psychology and we got an assigment to choose a scale and get at least 100 responds + prepare hypothesis and test them. I've got a scale (The Sexual Satisfaction scale for Women) where is 30 questinons and aswers are 1 to 5 points (1 is the least agreement with a statement and 5 is the most). I've got 103 respondets and 30 questins which I have to add, so at the end I have 103 numbers as a total score for each respondent and I can begin to work with my data. I put a part of the results below so you know how they like. Plus I have got 6 different hypothesis, every one of them has also 1 to 5 answer scale and I correlate them with total scores.



My homework is to find out how should my data look like to have Cronbach's alpha 0,74, average score 58, standard deviation (SD) 25,54. And how should my points look like to have the exact correlations that is given for each hypothesis. We didn't do this at school and I honestly have no idea what am I supposed to do.



I would be so grateful for your help!

Thanks, Johanna :wink:
