Introduction to Probability Distributions

Introduction to Probability Distributions. Random Variable. A random variable x takes on a defined set of values with different probabilities. For example, if you roll a die, the outcome is random (not fixed) and there are 6 possible outcomes, each of which occur with probability one-sixth.

The standard deviation is used to tell how far on average any data point is from the mean.

Computing Variance & Standard Deviation Name:_________________ Date:_______. The standard deviation is used to tell how far on average any data point is from the mean. The smaller the standard deviation, the closer the scores are on average to the mean.
