Answer:
Grade achieved is the dependent variable in the study.
Explanation:
A variable in any research or study is any property, characteristic, number, or a quantity which shows variability or change in its value i.e. it increases or decreases over time, depending on the treatment conditions.
There are two types of variables: Dependent variable and Independent variable.
An independent variable does not depent on any factor for its value or result, rather, a change units value brings about a change in the dependent variable.
A dependent variable is the variable which depends on some factor which the researcher controls. Any change made on the factor by the researcher would bring about a change on the dependent variable.
For example, in the given example above, studying habit affects academic performance. If a student studies more, his/her academic performance will improve as they will achieve higher grades. On the other hand, if a student fails to study, their academic performance will not show any improvement when compared to the group of students who studied. Thus, grade improvement depends on studying habit.
Therefore, grade obtained is the dependent variable in the study.
