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.
