I am analyzing the responses of a survey using spss statistics. I understand that I will need to do a Cronbach alpha first. But here is my problem:
The first part of my survey is "Awareness" and second part is "Attitudes". Under "Attitudes",there are 6 likert scale questions and 4 yes/no questions. So i was told to do data normalization before calculating Cronbach alpha for "Attitudes".
How should I do data normalization in spss?
Is data normalization same as transforming data in SPSS (arithmetric eg. Log10 or square root)? If so, how should I transform the yes/no questions? (my understanding is we can only transform likert-scale question)
I found very limited information in data normalization using spss.
Your answer is deeply appreciated. Thank you so much!!
