Question

Psychology majors at the state college consist of 40 percent males and 60 percent females. The psychology department is conducting a survey of its majors and obtains a sample by randomly selecting a group of 20 males and a group of 30 females from the list of majors. What kind of sampling is used in this example?

Answer 1

proportionate stratified random sampling

Step-by-step explanation:

When you use a proportionate stratified random sample, you must assign every stratum of the total population a sampling fraction proportional to its size. Since 60% of the psychology students are women, then 60% of the samples will come from women.
