Question

The weight (in kg) of 15 students of a class are:
38, 42, 35, 37, 45, 50, 32, 43, 43, 40, 36, 48, 43, 38, 47
16
Find the median of this data. Check if there is more than one mode.
142​

Answer 1

Step-by-step explanation:

n/2=16/2=8

n/2+1=16/2+2=10

there fore,

the median is the middle number of 8th and 10th

then the median is the middle number of 43 and 40

the answer is 42

Answer 2

first arrange data in acending order

32,35,36,37,38,38,40,42,43,43,43,45,47,48,50

median of odd number is

$(n + 1 \div 2 ) th term$

=

$(15 + 1 \div 2)thterm$

=(16/2) th term

=8 th term

8 th term is 42

so median is 42

There is one mode that is 43 because it occurred highest time then all other number
