Explanation:

From the question we are informed about Dr. Gibbs who gives a client the Wechsler Intelligence Scale for Children, and the results indicate an IQ of 118. The following week Dr. Gibbs administers the Stanford Binet Intelligence Scale to the same client, and the outcome is about the same. This match between two different measures of the same construct is an important part of establishing the scales' convergent validity.

Convergent validity can be regarded as term that gives how closely a particular new scale is been related to other variables as well as other measures of the same construct. We can measure Convergent validity with correlation coefficients. Instance of this is that there should be a positive correlation along with self-reported capability to move block as regards performance-based measure of moving.
