Statistics is the science or discipline of collecting, organising, analysing and presenting numerical data in huge quantities, in order to draw conclusions. For instance, finding the average height of students in a class or finding the average GDP of a country – all these are derived from statistics. Statistics is widely used especially in the government sector; in fields such as education, business, science, medicine, education, demography and more.
In this chapter, you’ll study various measures of statistics such as a measure of dispersion, range, mean deviation, standard deviation, frequency distribution and more.

15.3 Range
15.4 Mean Deviation
15.5 Variance and Standard Deviation
15.6 Analysis of Frequency Distributions
Section 15.2 – In this section, you’ll learn about various measures of dispersion such as range, quartile deviation, mean deviation and standard deviation. These measures of dispersion are based on the observations made and types of the measure of central tendency used.
