Project Description

The purpose of this study was to compare the difference in relative risk (RR) of lung cancer between the intervention and control groups.

The hypothesis was: The intervention group will have an increase in relative risk (RR) of lung cancer from pre to post while the control group will have no statistically significant change or may actually decrease.

We conducted a repeated measure ANOVA to test the hypothesis for this study. We performed three statistical tests at once in the present study (i.e., one for each of the two possible main effects and one for the possible interaction effect). The interaction effect was significant.  Thus, the intervention group had an increase in relative risk (RR) of lung cancer from pre to post while the control group had no statistically significant change (p<0.05).
