Answer:
Explanation:
You want the quartiles of the data set ...
{0, 0, 0, 1, 1, 1, 1, 2, 3, 4, 4, 4, 4, 5, 5, 5, 5, 5, 6, 6, 7, 7, 7, 7, 8, 8, 9, 9}
Quartiles
The number of elements in the set is 28, so the median (Q2) will be the average of the middle two.
Q2 = (5 +5)/2 = 5
The first half of the data set is 14 elements, so the first quartile (Q1) will be the average of elements 7 and 8.
Q1 = (1 +2)/2 = 1.5
Likewise, the last half of the data set is 14 elements, so the third quartile (Q3) will be the average of elements 21 and 22.
Q3 = (7 +7)/2 = 7
The quartiles of this data set are ...
