For each given situation, determine if the method of randomization is either appropriate or not appropriate. A car company is pe
rforming a survey to find out about people's driving habits in a certain city. They randomize the survey by talking to every 50th person who leaves a movie theater within this certain city. A laboratory wants to know how having chicken pox as a child has affected people's immune systems as adults. They randomize the study by assigning subjects to groups based on a random drawing. A university wants to test the health effects of a certain sweetener. Prior to testing the sweetener, they randomize the experiment by flipping a fair coin that assigns each person to the experimental or control group.
Determining if the method of randomization is either <u>appropriate</u> or <u>not</u> for each given situation includes:
A. Inappropriate
B. Appropriate
C. Appropriate.
<h3>What is randomization?</h3>
Randomization is the process of assigning research participants by chance to separate treatment groups.
Using a random drawing to assign subjects to groups and <u>flipping a fair coin</u> to assign participants to the experimental or control groups are instances of randomization.
Thus, the randomization method for experiment A is inappropriate, unlike experiments B and C.
