Fit Family Task Force Project - Rockford Public Schools

The results for each group were as follows:
Nashold (Experimental): Pre – 6.54 Post – 13.00 Difference – 6.46
Nashold (Control): Pre – 5.53 Post – 8.07 Difference – 2.53
Differences between control group and intervention group pre and post test scores at Nashold School
The figure above shows the change from pre to post test scores in both the
experimental and the control group at Nashold. A two tailed, paired t-test (as
previously described) was also performed for both groups. The results were as
follows:
Paired t-test comparing pre and post test scores:
Nashold (Experimental) 0.0000156
Nashold (Control) 0.0024928
Clearly, the experimental group had a much higher post test score and positive
difference between post and pre test scores than the control group. Thus, the p-
value was much lower for the experimental group than the control group.
Furthermore, 0/13 students from the experimental group recorded a lower score
on the post test than their pre test, while 3/15 students from the control group
recorded a lower score on their post test than their pre test.
