# Tell whether the statement is true or false:

(i) The mode is always one of the numbers in a data

(ii) The mean is one of the numbers in a data

(iii) The median is always one of the numbers in a data

(iv) The data 6, 4, 3, 8, 9, 12, 13, 9 has mean 9

**Solution:**

We use the concepts of mean, median and mode to solve the problem.

(i)True: Mode is the observations that occurs highest numbers of times. Therefore, it is one observation in a data.

(ii)False: Mean may or may not be one of the numbers in a data.

(iii)True: Median is the middle observations of the given data when it is arranged in ascending or descending order.

(iv)False: The given data 6, 4, 3, 8, 9, 12, 13, 9. Mean = 6 + 4 + 3 + 8 + 9 + 12 + 13 + 9 8

= 648

= 8

Therefore, the mean is 8.
