Question

Find the minimum, first quartile, median, third quartile, and maximum of each data set. Draw the box-and-whisker plot.77 99 82 88 95 91 68 79 81 89

Answer 1

We need to order the data on increasing way and we got:

68 77 79 81 82 88 89 91 95 99

We can see that we have 10 values then the median can be founded like this:

Median= (82+88)/2 = 85

Then we can find the first quartile with these values:

68 77 79 81

Q1 = (77+79)/2= 78

And the third quartile with these data:

89 91 95 99

Q3 = (91+95)/2= 93

Minimum = 68

Maximum = 99
