Question

How do you find the range of the data set?

Answer 1

We will understand the term range and see its definition. We will find the formula for calculation of range using its definition. For calculation of range, the most important thing is the lowest and the highest value.

Complete answer:
The range of your data in statistics is the range from the lowest to the greatest value in the distribution. It's a widely used metric for determining variability.
Measures of variability, like measures of central tendency, provide descriptive statistics for describing your data collection. By subtracting the lowest from the greatest value, the range is determined. A broad range in a distribution indicates great variability, whereas a narrow range indicates low variability.
The formula for calculation of range is:
Range= Highest value - Lowest value
The range is the most straightforward way to calculate variability. Follow these procedures to determine the range: From low to high, sort all of the values in your data collection. Subtract the smallest number from the largest.
Whether your values are positive or negative, whole numbers or fractions, the method remains the same.

Note: The limitations of range is because it is so sensitive to outliers, the range is a very basic and basic assessment of data dispersion. As a result, the usefulness of a real range of a data set for statisticians has certain restrictions. This is due to the fact that a single data value can have a significant impact on the range's value.
