Question
A psychologist designed and conducted a study to determine whether playing a certain educational game increases middle school students' accuracy in adding fractions. For the study, the psychologist chose a random sample of 35 students from all of the students at one of the middle schools in a large city. The psychologist found that students who played the game showed significant improvement in accuracy when adding fractions. What is the largest group to which the results of the study can be generalized?
- The 35 students in the sample
- All students at the school
- All middle school students in the city
- All students in the city
The correct answer is: All students at the school
The sample of an experiment must be large.
The all middle school students in city will be too large.
Thus, we come to all students in a school.
