<h3>Dependent Variable: exam performance</h3>
The variable that depends on other factors that are measured.
<h3>What is a Dependent Variable ?</h3>
A dependent variable is the variable that changes as a result of the independent variable manipulation.
- For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants' test scores since that is what is being measured.
- The easiest way to identify which variable in your experiment is the Independent Variable (IV) and which one is the Dependent Variable (DV) is by putting both the variables in the sentence below in a way that makes sense. “The IV causes a change in the DV. It is not possible that DV could cause any change in IV.”

Answer:Cronbach's alpha
Explanation:
Cronbach's alpha is used to measure consistency interms of how closely associated items in a group are.
It measures the scale of reliability as a coefficient of reliability not statistically.
below is a formula that is used to calculate this reliability.
α=N¯c/¯v+(N−1)¯c
Here N equate to the number of items, ¯c is the average inter-item covariance among the items and ¯v equals the average variance.
The increase number of items will increase Cronbanch's Alpha.
Additionally, if the average inter-item correlation is low, alpha will be low.
