The following number of goals were scored by a team in a series of 10 matches 2, 3, 4, 5, 0 1, 3, 3, 4, 3 Find the mean, median and mode of these scores.

Answer» First we arrange scores in ascending order.
Scores in ascending order are `0,1,2,3,3,3,3,4,4,5.`
`:.` Mean of the scores ` = (0+1+2+3+3+3+3+4+4+5)/10 = 28/10 = 2.8`
Median will be the mean of `(10/2)^(th) and (10/2+1)^(th)` terms.
`:.` Median `= (T_5+T_6)/2 = (3+3)/2 = 3`
Mode is `3` as it has maximum frequency and appeared `4` times in the given data.
