In order to estimate expected scores for the norm sample, existing data may be divided into smaller units for establishing tables of developmental scores through a process called which of the following?
A) Extrapolation
B) Interpolation
C) Standard scores
D) Stanine

Question

Quizplus · Accepted Answer

Interpolation is a statistical technique used to estimate values within a range of existing data points. By dividing existing data into smaller units, it is possible to establish tables of developmental scores, representing an estimate of expected scores for the norm sample. Extrapolation is the process of estimating values outside the range of existing data points, while standard scores and stanines are different types of scoring systems used to interpret test results.
