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.
    • 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)
    • da-release-figure1.png

  • 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).
