Subject: need a paired difference statistical analysis
Details: I am writing a thesis and need a paired difference statistical analysis with a confidence level at 95% with t-value for alpha of 0.25
My hypothesis is that there is a statistically significant differnce between two test scores for the following samples (pre and post tests)
1. 17 15
2. 27 24
3. 33 33
4. 31 30
5. 32 25
6. 32 21
7. 38 26
Is this the correct way to measure if an intervention was successful for seven samples?
(I gave a pre and post test)
