Question

which statement about coefficient alpha is correct?

A) when the measurement error increases, alpha increases.

b) when the correlation between items and the total score decreases, alpha increases

C) when the correlation between items increases,alpha increases

D) when a tests includes many similar items, alpha decreases.

Answer 1

Option B is the correct answer.

Option B

Because

When deciphering the α coefficients of a scale, recall that a excessive α is each a part of the covariances between matters as properly as the quantity of things in the investigation, so a excessive α constant isn't all by using itself a signal of a reliable arrangement of things; you'll regularly amplify the α coefficient typically with the aid of growing the. If the value of alpha increase the total item values decreases.
