Question

1. Are patches more effective than oral medication in helping individuals stop smoking? Two researchers had 22 people who were randomly assigned to one of the two treatment groups, with 11 people assigned to each. The subjects were monitored for six weeks, during which they received treatment every day—a new patch for subjects in the first group and a single pill for subjects in the second group. The researchers reported that subjects wearing the patches were less likely to quit smoking, although the difference was not statistically significant. This study is a(n) (a) convenience sample. (b) observational study. (c) experiment, but not a double-blind experiment. (d) double-blind experiment.

Explanation / Answer

This is for sure experimental study as we are doing experimental on two groups with different procedure.

But we find that there is some biases in the experimental as output is different than statistics.

Double blind experiment means A testing procedure, designed to eliminate biased results, in which the identity of those receiving a testtreatment is concealed from both administrators and subjects until after the study is completed.

So answer is c. experimental, but not a double blind experiment
