### About Exercise 15.1 of 11th Maths

Statistics has been discussed in 11th Mathematics NCERT chapter 15. Statistics is a practical subject. However, the term statistics is used in two different senses. In one sense it represents collection of data. According to A. L. Boddington, statistics is referred to as science of averages and their estimates. Statistics also means analyzing and interpreting the given data.

#### Central Tendency in Exercise 15.1

Almost half of 11th Mathematics chapter 15 is a mere revision of the measure of central tendency which you have already studied in class 10. Central tendency refers to the act of finding the representative value for a given data. Arithmetic mean, median and mode are the three measures of central tendency.

Calculation of arithmetic mean is the simplest. All these three can be calculated in case of individual data, discrete series and continuous series. These measures give us a rough idea about the data and question.
