Detailed explanation-1: -Continuous variables are generally measured on scales such as height, weight, temperature, etc. With the help of continuous variables, one can measure mean, median, variance, or standard deviation. Continuous variables are the ones which in between any two numeric values have an infinite number of values.

Detailed explanation-2: -The most widely used measure of variability for a continuous variable is called the standard deviation, which is illustrated below.

Detailed explanation-3: -Range is one of the simplest measures of variation. It’s the lowest point of data subtracted from the highest point of data. For example, if your highest point is 10 and your lowest point is three, your range would be seven. The range tells you a general idea of how widely spread your data is.

Detailed explanation-4: -What are the 3 measures of variation? We looked at three types of variation measures: range, IQR, and variance (and its square root counterpart – standard deviation).

Detailed explanation-5: -Statisticians use summary measures to describe the amount of variability or spread in a set of data. The most common measures of variability are the range, the interquartile range (IQR), variance, and standard deviation.
