Question

The weight in kgs of 15 student of a class are 38, 42, 35, 37, 45, 50 , 32 , 43 , 43 , 40 , 36 , 38 , 43 , 38 , 37 find the mode and median of this data is there more than one mode

Answer 1

Answer:

Mean = 39.8 kg, median = 38 kg, mode = 38 kg and 43 kg

Step-by-step explanation:

Mean = (38+42+35+37+45+50+32+43+43+40+36+38+43+38+37) ÷ 15

= 597 ÷ 15 kg

= 39.8 kg

In ascending order,

32,35,36,37,37,38,38,38,40,42,43,43,43,45,50

N = 15 , odd.

Median = ( n+1)÷ 2 th term

= (15+1) ÷ 2 th term

= 8th term

= 38 kg

Mode = number with highest frequency

Here, both 38 and 43 occur 3 times.

So, mode = 38 kg, 43 kg.
