During the period 1940-1980, 28 deaths from lung cancer were discovered among the workers. Only eight lung cancer deaths, however, were reported among a comparable group of 800 coworkers who did not work with insulation during the same time period.

What kind of study has a post-test but no baseline measurement?

A: Survey
B: True Experiment
C: Placebo-Controlled study
D: Double-blind study

Answers

The kind of study that has a post-test but no baseline measurements is a placebo-controlled study. So the correct option is C.

What is a placebo-controlled study?

This is a study performed during human- trials of a drug. In this study, the people selected for the trial are divided into two groups. One group gets the actual drug or the active treatment and the other group is given a placebo.

A placebo is a substance that has a look and taste similar to the actual drug but it contains no active substance as the drug. This is given to eliminate the chance of a placebo effect.

A placebo is a tendency to feel better when we are receiving treatment for a disease even if the treatment is not having an actual effect.

Since, in a placebo-controlled study, the two groups do not know if they are receiving the actual drug or the placebo, the chances of a placebo effect occurring are reduced to a minimum.

Thus, a placebo-controlled trial is required for a drug trial.

therefore, the correct option is C.
