Question

15 students weight are given below. Find the mean, median,mode,range. 38,42,35,45,50,32,43,43,40,36,38,43,38,47

Answer 1

Answer:

Let us arrange the data in ascending order

32,35,36,37,38,38,38,40,42,43,43,43,45,47,50.

i) Mode = 38 and 43 as they occured the maximum number of times

Median = \left(\frac{n+1}{2}\right)^{th}\(

2

n+1

)

th

n = 15

\frac{15\ +\ 1}{2}

2

15 + 1

= \frac{16}{2\ }\ =\ 8th\ term

2

16

= 8th term

8th term = 40

Thus, mode of the data is 38 and 43

Median = 40

ii) Yes, the given data has two modes.
