Which type of study will a researcher prefer to estimate the degree of relationship between the level of education and achievement motivation?
ANaturalistic
BInventory
CCorrelational ✓ Correct
DExperimental
Correct answer: (C) Correlational — To estimate the degree of relationship between two variables, a correlational study is preferred, so that is the answer.
Explanation
★To estimate the degree of relationship between two variables, a correlational study is preferred, so that is the answer.
★A correlational study measures how two variables relate without manipulating either.
★So it directly estimates the degree of relationship between education level and achievement motivation.
★A naturalistic study observes behaviour in its setting but does not measure a degree of relationship.
★An inventory is a listing instrument, not a design for measuring relationship.
★An experimental study manipulates a cause, which is not needed here, so a correlational study is preferred.
