In a statistics class, two groups are identified; males and females.

Five students are selected from these two groups randomly.

02

Step 2:Identify the method of sampling

Stratified sampling is the method of gathering participants in the following manner:

  • Select the population
  • Divide the population into strata based on certain variables.
  • Select the random participants from each of the strata.

In the study, the population to be studied is a statistics class, and the students are divided into two stratabased on gender.

Hence, random selections of five are made from each of the groups.

Thus, the sampling method is stratified sampling.

IQ Scores Most people have IQ scores between 70 and 130. For $39.99, you can purchase a PC or Mac program from HighIQPro that is claimed to increase your IQ score by 10 to 20 points. The program claims to be “the only proven IQ increasing software in the brain training market,” but the author of your text could find no data supporting that claim, so let’s suppose that these results were obtained: In a study of 12 subjects using the program, the average increase in IQ score is 3 IQ points. There is a 25% chance of getting such results if the program has no effect.
