a group of friends each plant a certain number of saplings on environment day find the median and mean numbers of saplings planted 30,25,47,18,15

Answer:

Mean = 27, median = 25

Step-by-step explanation:

Data in arrayed form(ascending/descending) :

15 , 18 , 25 , 30 , 47

mean = sum of the observations / No. of observations

mean = 15+18+25+30+47 / 5

= 27

Median = n + 1 / 2 [n = no. of terms]

= 5 + 1 / 2

= 3

3rd observation = 25
