For the given set of data 5-Number summary is as follows
Max = 80
Min = 21
Q1 (First Quartile) = 28
Q2 (Median) = 33.5
Q3 (Third Quartile) = 39.75
We can further calculate, interquartile range
IQR = Q3 - Q2 = 39.75 - 28 = 11.75
Further lower and upper fences can be calculated to identify the outliers
lower fence = Median - 3*IQR = 33.5 - 3*11.75 = -1.75
upper fence = Median + 3*IQR = 33.5 + 3*11.75 = 68.75
Values which are above 68.75 are outliers in the given data.
Let me know if you are looking for any other analysis from this data.
