Answer:

Median = 31.5

Mean = 32.25

Explanation:

Number of data = 8

Ascending order:

30 , 30 , 31 , 31 , 32 , 33 , 35, 36

Median = Average of 4th and 5th term

= (31 + 32) / 2

= 63/2

= 31.5

Mean = Sum of all the observations /number of observations

= (31 + 32 + 36 +31 + 30 + 35 + 33 +30) / 8

= 258/8

= 32.25
