Question

Quizplus · Accepted Answer

A standard normal table is used to find the area under the standard normal curve corresponding to a given Z score or its fraction. The Z score is a measure of how many standard deviations an observation or data point is from the mean of the population. The standard normal curve is a bell-shaped curve with a mean of 0 and a standard deviation of 1. Therefore, the Z score is a standardized score that measures how many standard deviations an observation is from the mean of the standard normal distribution. The standard normal table allows us to find the area under the curve corresponding to a given Z score or its fraction, which is useful in various statistical and probability applications.
