Question

Does being part of a support group affect the ability of people to quit smoking? A county health department enrolled 300 smokers in a randomized experiment. 150 participants were assigned to a group that used a nicotine patch and met weekly with a support group; the other 150 received the patch and did not meet with a support group. At the end of the study, 40 of the participants in the patch plus support group had quit smoking while only 30 smokers had quit in the other group.

Create a two-way table presenting the results of this study.

Answer 1

The table would be:

| Quit Smoking | Did Not Quit Smoking | Total

Patch + Support Group | 40 | 110 | 150

Patch Only | 30 | 120 | 150

Total | 70 | 230 | 300

A two-way table can be created to present the results of the study. In this case, the two factors are the use of a support group (yes or no) and the success of quitting smoking (yes or no).

The rows represent the two groups: "Patch + Support Group" and "Patch Only."The columns represent the two outcomes: "Quit Smoking" and "Did Not Quit Smoking."The numbers in the cells indicate the count of participants falling into each combination of group and outcome. The "Total" row and column show the overall distribution of participants across the study.
