(i) When values in data are close to each other, then we can use mean as an appropriate measure of central tendency.
For example,
`1.1,1.3,1.4,1.5,1.7`
In the above data, mean will give appropriate measure of central tendency.
(ii) Sometimes values in the given data are not close to each other. In that case, the mean is not an appropriate measure of central tendency but the median is an appropriate measure of central tendency.
For example,
`3,15,29,4,112`
In the above data, the mean will not give an appropriate measure of central tendency but the median will give an appropriate measure of central tendency.
