Question

Standardized z_iscores can be obtained as: Z_i= (X - X)/s.

Quizplus · Accepted Answer

The formula for standardized z-scores is Z = (X - μ) / σ, where X is the raw score, μ is the mean, and σ is the standard deviation. The given formula, Z = (X - X) / s, is incorrect because it uses the sample mean (X) instead of the population mean (μ) and the sample standard deviation (s) instead of the population standard deviation (σ).
