Question

A data set is Normally distributed with a mean of 25 and a standard deviation of 8. If you calculate the standard score of every observation in this data set, the resulting scores will have a distribution that has

Answer 1

The answer is "A mean of 0 and a standard deviation of 1".

Explanation:

The standard answer of its following formula is calculated by:

`\to z=(X-\mu)/(\sigma)`

Its standard score relates to the sampling distribution with the normal distribution average standard variation of 0 and 1, correspondingly. The mean for a standard scoring is 0, and the normal deviation is 1. that's why the mean=0, standard deviation=1.
