Accordingly to NCERT Solutions for Class 9 Maths Chapter 14, Statistics deals with collecting, presenting, analysing, and interpreting data. Data can be either ungrouped or grouped. Further, grouped data could be categorised into:
(a) Discrete frequency distribution and (b) Continuous frequency distribution.
Data can be represented in tables or the form of graphs. Common graphical forms are bar charts, pie diagrams, histograms, frequency polygons, ogives, etc.
The first order of comparison for a given data is the measures of central tendencies. Commonly used measures are (i) Arithmetic mean (ii) Median (iii) Mode.
Median is the measure that divides the data into two equal parts. The median is the middle term when the data is sorted. In the case of odd observations, the middle observation is the median. In the case of actual observations, the median is the average of the two middle observations. The median can be determined graphically. It does not take into account all the observations.

The relationship between the mean, median, and mode of a data set is crucial to understanding statistics. The difference between mean and mode equals three times the difference between the mean and median.
3 Median = 2 Mean + Mode
