Question

1. Find the median of the given data. (1) 7, 3, 5, 7, 9, 11, 3, 8, 5, 44, 40, 55, 48, 44.58, 67​

Answer 1

Step-by-step explanation:

ascending order of observation:

3,3,5,5,7,7,8,9,11,44,44.58,48,55,57

n=15,which is odd no. so

median=(n/2th observation + n/2+1 observation)÷2

i.e. (14/2 th observation + 14/4+1 th observation)÷2

=(7th observation+8th observation)÷2

=(8+9)÷2

=17÷2

=8.5

Answer 2

Answer:

First arrange them in ascending order we get -

3,3,5,5,7,7,8,9,11,40,44,44.58,48,55,67

Step-by-step explanation:

Now count them and find the middle number -

total no - 15

subtract 1 we get 14

then

7+7 = 14

== 3,3,5,5,7,7,8, 9 , 11,40,44,44.58,48,55,67

So 9 is medien
