Question

Quizplus · Accepted Answer

The perfect normal curve that serves as a model for any approximately normal z-distribution is called the standard normal curve or the standard normal distribution. It has a mean of 0 and a standard deviation of 1, and all scores are represented as z-scores. Therefore, the correct answer is C, the standard normal curve. Choices A, B, and D are not correct because they either refer to different types of distributions or do not exist as standard statistical terms.
