Recent research has demonstrated that music-based physical training for elderly people can improve balance, walking efficiency, and reduce the risk of falls (Trombetti et al., 2011). As part of the training, participants walked in time to music and responded to changes in the music’s rhythm during a 1-hour per week exercise program. After 6 months, participants in the training group increased their walking speed

and their stride length compared to individuals in the control group. The following data are similar to the

results obtained in the study.

Exercise Group

Stride Length

24 25 22 24 26 17 21 22 22 19 24 23 23 28 25 23

Control Group Stride Length

26 23 20 23 20 16 21 17 18 23 16 20 25 19 17 16

Do the results indicate a significant difference in the stride length for the two groups? Use a two-tailed test with a = .05. Make your decison. Enter your data into SPSS.
