Question

Find the mean and median of the
given data set.70, 68, 56, 62, 56, 66,
56​

Answer 1

56,68,89,52,14,63,78,80.

Answer 2

Answer:

Given data: 70, 68, 56, 62, 56, 66,56

Mean:

${ \sf{Mean = \frac{Sum \: Of \: Observations}{Number \: Of \: Observations} }} \\ \\ { \sf{Mean = \frac{70 + 68 + 56 + 62 + 56 + 66 + 56}{7} }} \\ \\ { \sf{Mean = \frac{434}{7} }} \\ \\ { \sf{Mean =62}}$

Median:

Let us arrange the given data in ascending order

➙ 56 , 56 , 56 , 62 , 66 , 68 , 70

Median in ungrouped data is the middle term

➙ So, the middle term is 62

➙ Median = 62

${ \therefore{ \sf{ \bold{Mean = 62}}}}$

${ \therefore{ \sf{ \bold{Median = 62 }}}}$
