Thanks for asking me

Answer 2

158 cm is median height

Step-by-step explanation:

The heights (in centimetre) of 10 members of a society are: 156, 175, 162, 135, 160, 150, 160, 150, 155, 167

Arranging in ascending order

135 , 150 , 150 , 155 , 156 , 160 , 160 , 162 , 167 , 175

10 Members

Median = (5th + 6th)/2 = (156 + 160)/2 = 158

158 cm is median height

The marks of 11 students out of 25 are as follows:

21,20, 13, 15, 10, 20, 15, 21, 18, 20, 14

Arranging in ascending order

10 , 13 , 14  , 15 , 15  , 18 , 20 , 20 , 20 , 21 , 21

Median = 18

Mode = 20  

Range = 21 - 10 = 11

Mean = ( 187/11) = 17
