Question
41. Below is data from a study which used a measure of self-esteem (scored from 0-100) and academic achievement (scored from 0-100). The purpose of the study is to determine the relationship between self-esteem and science learning in middle school students in order to support teacher-student/parent relationships (n=15).

Explanation / Answer
1. These are interval scores because there is an equal interval between each scores and there is also an assumption of an arbitrary zero point (as the lowest score in each variable would be represented by 0).
2. This is a correlational study as the intention is to describe the nature and extent of relation between the two variables, that is, self esteem and science learning.
3. Null hypothesis: There exists no relationship between self esteem and academic achievement in science among middle school students.
4. Alternative hypothesis: There exists a positive and significant relationship between self esteem and academic achievement in science among middle school students.
