Median is a value or quantity that lyes at the midpoint of a frequency distribution.
A) To find the median in this data we will have to rearrange the data in either ascending or descending order and pick out the value that fall at the midpoint.
36, 45, 29, 39, 51, 49 will be rearrange as
29, 36, 39, 45, 49, 51, since we have 6 data in this distribution the midpoint value will be 39 and 45.
Therefore median = (39+45)/2
Median = 42.
B) Of course we can still find the median. All we need to do is convert the rest of the weight to kilograms.
For instance
If 51 pound is convert to kilograms
Approximately 2.205 pounds = 1kilogram
51 pounds = 23.13kg
We convert the rest of the weight to kilograms.
29 pounds = 13.15kg
36 pounds = 16.33kg
39 pounds = 17.69kg
45 pounds = 20.41kg
49 pounds = 22.23kg
Arranged in ascending order
13.15, 16.33, 17.69, 20.41, 22.23, 23.13
Median = (17.69+20.41)/2
= 38.1/2
= 19.05kg
Now let cross check by convert back to pound
19.05kg = (19.05 x 2.205)pounds
= 42.005 ~ 42pounds
So we are right.
