question 58

Essay

Dr. Phillips is a cognitive-developmental psychologist who studies how children learn mathematical principles. His current interest is in studying how children learn multiplication. He recruits 54 second-graders who have not yet learned how to multiply numbers to participate in his study. He is curious as to whether different teaching styles lead to better mastery of the subject. One condition (A) involves having students read a chapter on multiplication from their textbook. One condition (B) involves having students watch a video of cartoon characters explaining multiplication. One condition (C) involves having students being taught multiplication by a teacher. One condition (D) involves having students being taught multiplication by a fourth-grader. In all conditions, participants spend 30 minutes learning the fundamentals of multiplication and are then given the same 15-question multiplication test. The number of questions answered correctly is recorded. The data are below.

Using Dr. Phillips' study as an example, explain the difference between a control group and a comparison group. Why did Dr. Phillips' study not have a control group?

Understand the concept and application of market segmentation.

Distinguish between different types of segmentation: demographic, psychographic, geographic, geodemographic, and behavioural.

Recognize psychographic segmentation's role in predicting consumer behavior.

Identify how lifestyles, values, and self-concept influence consumer choices.
