Question

Download the data set bph-samp.sav and use SPSS to complete the following calculations:

1) Run a paired t test to compare if there is a mean change in QoL at the baseline and at 3 months.

2) Run a one-sample t test to test the same hypothesis as in (1) but on the variable DELTA.

3) Check if the QoL at the baseline and at 3 months follow Normal distributions.

4) If you have a concern about the small sample size and perhaps non-normal data, choose an appropriate nonparametric test to compare the median QoL score at the baseline and at 3 months. (Hint: You need to research nonparametric tests.)
