Suppose a researcher wants to study the effectiveness of a new reading program for students who have not acquired the necessary reading skills by the time they reach the 8th grade. A randomly selected group of 50 students from a local junior high with poor reading skills will undergo a special reading program. Another group of 50 randomly selected students with poor reading skills will undergo regular reading classes. A month later, the reading skills of all 100 students are assessed to determine whether the program was successful.
What are the two populations of interest in this study?
- Population I: Students with poor reading skills who undergo the new reading program
- Population II: The general population
n of readers
- Population III: The students with poor reading skills who undergo regular reading classes.
- Both A and C are correct
To quote one of our very good math and science tutors: “You will find here at Jiskha that long series of questions, posted with no evidence of effort or thought by the person posting, will not be answered. We will gladly respond to your future questions in which your thoughts are included.”
- Both A and C are correct
The two populations of interest in this study are:
- Population I: Students with poor reading skills who undergo the new reading program
- Population III: The students with poor reading skills who undergo regular reading classes.
Both A and C are correct.
Population I refers to the group of students with poor reading skills who undergo the new reading program. This group is the focus of the study to evaluate the effectiveness of the program.
Population III refers to the students with poor reading skills who undergo regular reading classes. This group serves as a comparison or control group to assess the effectiveness of the new reading program.
Population II refers to the general population of readers. While not directly involved in the study, this population represents the broader context in which the study is conducted.
