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. - Dopamine levels (nM) - Animal ID - Presong exposure - During song exposure - y33 - 35 - 37 - y34 - 22 - 30 - y35 - 25 - 27 - y36 - 23 - 29 - y37 - 31 - 35 - y38 - 20 - 22 - Mean - 26.0 - 30.0 - SEM - 2.4 - 2.2 
 
- 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).
