The range is the easiest measure of variability to calculate. To find the range, follow these steps: 1 Order all values in your data set from low to high. 2 Subtract the lowest value from the highest value.
How to find the range of a distribution?
The range is calculated by subtracting the lowest value from the highest value. While a large range means high variability, a small range means low variability in a distribution.
What is the best way to use range?
To get a clear idea of your data’s variability, the range is best used in combination with other measures of variability like interquartile range and standard deviation.
Why is the range always zero?

If you need to find the median of an even-numbered set of ordinal data, convert each value to a number and treat it like a numerical data set. Find the average of the middle values to calculate the median. While not completely accurate, this method can be an acceptable alternative.
Why do we use median instead of mean?
You might choose to find a data set's median, rather than its mean or mode, to avoid outliers, or disproportionately low or high numbers, in your statistical analysis. Outliers can create an average that does not accurately represent a group of numbers. Therefore, the median is sometimes the more accurate figure to use in your analysis.
