Example 12: The heights (in cm) of 9 students of a class are as follows:
155 160 145 149 150 147 152 144 148
Find the median of this data.
Example 13: The points scored by a Kabaddi team in a series of matches are as follows:
17, 2, 7, 27, 15, 5, 14, 8, 10, 24, 48, 10, 8, 7, 18, 28
Find the median of the points scored by the team.
Measures of Central Tendency
Very often we need to analyse a given data to find a value that can represent the entire data set. In other words we say the central tendency of the data set. Different types of data would require different methods to find this central value which can be used as the representation of the entire data set. For example, average number of students can be find using the mean of the data, splitting apples in large sized and small sized groups would require median and for a shoe company mode will be the best measure to decide about the investment.
So, following are three measures of central tendency that you must understand by watching the video embedded below.
- Mean
- Median
- Mode
