Question

Which of the following measures the average deviation of the random variable from the mean in a discrete probability distribution?

1) Mean
2) Median
3) Mode
4) Standard Deviation

Answer 1

The standard deviation measures the average deviation of a random variable from the mean in a discrete probability distribution.

Step-by-step explanation:

The standard deviation measures the average deviation of a random variable from the mean in a discrete probability distribution. It is a measure of the variability or spread of the possible outcomes. The standard deviation is calculated by taking the square root of the variance, which is the average of the squared differences between each outcome and the mean.
