| Introduction |
|
| When some data is colleted, we have certain numbers which represent the characteristics of the data, around which the data appears to be concentrated, we call such numbers as the measures of central tendency. There are three measures of central tendency. |
| |
| (i) Mean |
| |
| (ii) Median and |
| |
| (iii) Mode. |
| |
| In this chapter, we will study about Mean only; Median and Mode will be dealt with in the next chapter. |
