A total of 850 insulation workers employed between 1940 and 1945 was identified from the personnel records of three large insulation manufacturing plants in the Midwestern U.S. in 1980. 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. The investigators had hypothesized that exposure to the insulation material increases the risk of lung cancer.

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.
