How do you tell if there are outliers in a 5 number summary?


Click to see full answer.

Keeping this in view, do you include outliers in 5 number summary?

The five numbers are the minimum, the first quartile(Q1) value, the median, the third quartile(Q3) value, and the maximum. The first thing you might notice about this data set is the number 27. This is very different from the rest of the data. It is an outlier and must be removed.

Beside above, what is the purpose of a 5 number summary? The five-number summary gives information about the location (from the median), spread (from the quartiles) and range (from the sample minimum and maximum) of the observations.

Simply so, what defines an outlier?

Usually, the presence of an outlier indicates some sort of problem. A convenient definition of an outlier is a point which falls more than 1.5 times the interquartile range above the third quartile or below the first quartile. Outliers can also occur when comparing relationships between two sets of data.
