Blood Platelet Counts If we collect a sample of blood platelet counts much larger than the sample included with Exercise 3, and if our sample includes a single outlier, how will that outlier appear in a histogram?

Short Answer

Expert verified

The outlier in the histogram will be far apart from the rest of the observations along the horizontal axis.

Step by step solution

01

Given information

A sample of sufficient size is considered, which shows the blood platelet counts of adult males. A histogram is plotted for the sample.

The sample includes an outlier.

02

Outlier in a histogram

An outlier is an observation that is either too low or too high from the majority of the observations in the sample.

If a histogram is plotted for a sample containing an outlier, the outlier will appear separately at a distance from the other observations along the x-axis.

Here, the sample of blood platelet counts of adult males consists of an outlier.

This outlier will appear far off from the remaining observations on the histogram along the horizontal axis.
