Question
Chapter 11.1, Problem 11PPS
To determine
To find: Whether the given situation describes a survey, an experiment, or an observational study.
Expert Solution & Answer
Explanation of Solution
Given information:
The given situation is, “A research group randomly selects 80 college students, half of whom took a physics course in high school and compares their grades in the college physics course”.
Concept used:
Survey: In a survey, data are collected from the responses given by members of a population regarding their characteristics, behaviours, or opinions.
Experiment: In an experiment, the sample is divided into two groups:
- An experiment group that undergoes a change, and
- A control group that does not undergoes the change.
Observational study: In an observational study, members of a sample are measures or observed without being affected by the study.
In the given situation, two groups are observed based on the grades, so as per the definition of the observation study that is members of a sample are measures or observed without being affected by the study, the given situation is an observation study. The sample of the members should be all college students.
