Practice Problem - Answer/Results
Effect of Early Song Exposure on DA Release within the Avian Basal Ganglia
- First, calculate the group means/SEM so you can get a general feel for the data.

- Next, enter the data into Prism and run the appropriate analysis.
- NOTE: You should use PAIRED t-test for these data (unpaired yields p=.246)
- Finally, construct a summary statement that accurately reflects the results obtained. For example:
Compared to baseline (before song exposure), DA levels were significantly elevated after song exposure (t=3.873, df=5, p<.02).
