Discrete data can only take certain values (such as 1,2,3,4,5) continuous data can take any value within a range (such as a person's height) here we looked only at discrete data, as finding the mean, variance and standard deviation of continuous data needs integration. Standard deviation in statistics, typically denoted by σ, is a measure of variation or dispersion (refers to a distribution's extent of stretching or squeezing) between values in a set of data.
