Question

Find the median of the following data.
(a)=3,12,6,7,8,10,11,9,8,15
(b)=75,60,55,65,80,60,85,50, 75,80,50,65
(c)=125,420,215,180,195,230, 365,540,690
(d)=7.2,5.6,1.8,4.3,2.6,9.1,3.4​

Answer 1

Answer:

(a) 8.5

(b) 65

(c) 230

(d) 4.3

Step-by-step explanation:

To get the median, sort the data then take the middle value.

When there are two middle values, take their average.

(a) Sorted: 3, 6, 7, 8, 8, 9, 10, 11, 12, 15

There are 10 values in total.  The two middle values are the 5th and 6th (underlined).  So the median is (8+9)/2 = 8.5

(b) Sorted: 50, 50, 55, 60, 60, 65, 65, 75, 75, 80, 80, 85

There are 12 values.  The middle values are the 6th and 7th.

So the median is (65+65)/2 = 65

(c) Sorted: 125, 180, 195, 215, 230, 365, 420, 540, 690

There are 9 values.  The middle value is the 5th.

So the median is 230

(d) Sorted: 1.8, 2.6, 3.4, 4.3, 5.6, 7.2, 9.1

There are 7 values.  The middle value is the 4th.

So the median is 4.3

Hope this helps!

Answer 2

median are the middle term

first arrange them in asscending order and take the middle number if the middle numbers are two so add them and divide it by 2.
