Question

2. Find the median and mode for the set of numbers:

a. 2, 5, 6, 8, 7, 2, 3, 9, 12, 10, 11, 6, 5, 18
b. 18.5, 21.7, 19.3, 25.4, 16.7, 28.5, 17.2, 20.1

Answer 1

Since median is the middle number or the two middle number added together divided by two
and
mode is the number with the highest frequency....

a.
2 2 3 5 5 6 6 7 8 9 10 11 12 18
6 and 7 is the middle two number
Hence 6+7=13
13 divide by 2= 6.5
Median=6.5

The numbers with the highest frequency is 2, 5, 6.....
Mode=2, 5 and 6

b.
16.7 17.2 18.5 19.3 20.1 21.7 25.4 28.5
18.5 and 19.3 is the middle two number
Hence 18.5+19.3=37.8
37.8 divide by 2= 18.9
Median=18.9

Mode= no mode
