Final answer:
The standard deviation measures the dispersion of the outcome of a discrete random variable in relation to the distribution's mean.
Step-by-step explanation:
The standard deviation measures the dispersion of the outcome of the discrete random variable in relation to the distribution's mean. It is a number that measures how far data values are from their mean. The formula to find the standard deviation of a discrete random variable X is o = √Σ(x − µ)² P(x), where x represents the values of the random variable X, µ is the mean of X, and P(x) represents the corresponding probability.
