Which statistical tool allows us to predict a dependent score based on information about an independent variable?

Solution

A regression model helps us to predict the value of dependnet variable based on the values of known independnet variables.

A regression model is of the form -

Y = a₀ + a₁X₁ + a₂X₂ +.................+a_nX_n

So, option a) regression is the answer.
