Solution
find the minimum first quartile median third quartile and maximum of each data set 12 10 11 7 9 10 and 5? We can order the dataset from the minimum to the maximum and we got:
5 7 9 10 10 11 12
The we can see that the
Minimum = 5
Maximum = 12
Since we have n=7 values the median would be the value in the position (n+1)/2 = (7+1)/2= 4th position
Median =7
the first queartile would be:
Q1 = (7+9)/2 = 8
And the third quartile would be:
Q3 = (10+11)/2= 10.5
