SPSS job interview questions

 
1. What is data view and variable view?
• In Data View, columns represent variables, and rows represent cases (observations).
• In Variable View, each row is a variable, and each column is an attribute that is associated with that variable.



2. What statistics analysis is included in SPSS?
3. How to calculate the effect of educational intervention to drug prescription?
We can input the drug prescription status  (yes or no) before and after educational intervention.  We can calculate the odds ratio using logistic regression in SPSS.

4. How to calculate the effect of educational intervention to drug dose in prescription?

 We used a matched pair for magnitude of drug dose before and after intervention  and analyze it using  student t-test in SPSS.
