Question

fill in the blank 2 points the average of the squared deviation of each data point from the mean: choose your answer... the average distance each data point is away from the mean: choose your answer... a normal distribution whose mean is 0 and standard deviation is 1: choose your answer... the number of standard deviations away from the mean (either above or below) any data value is in a normal distribution: choose your answer... variance standard deviation z - score standard normal distribution or standard normal curve

Explanation:

Step1: Recall variance definition

Variance is the average of the squared deviations of each data - point from the mean.

Step2: Recall standard normal distribution definition

A standard normal distribution has a mean of 0 and a standard deviation of 1.

Step3: Recall z - score definition

The z - score is the number of standard deviations a data - point is away from the mean.

Answer:

  1. variance
  2. standard normal distribution
  3. z - score
