Answer:
Given data set is : 2 6 12 8 3 9 14 20
We shall re-arrange the set of numbers in ascending order to get a clear concept:
2 3 6 8 9 12 14 20
1. Minimum: The minimum is the least value of the data set that is 2.
First quartile: The first quartile value is the median for the numbers before the median. 2 3 6 8 the value is [tex]\frac{2+3+6+8}{4}= 4.75[/tex]
Median: The average of the center two numbers. [tex]\frac{8+9}{2}[/tex]=8.5
Third quartile: The third quartile is the same as first but take last 4 values, 9 12 14 20 the value is [tex]\frac{9+12+14+20}{4}= 13.75[/tex]
Maximum: The highest value number in the data set which is 20.
