Now create your graph. This graph shows all the ages of the people who live in the apartment building. It shows the youngest person is 30, and the oldest is 58. Most people in the building are over 46 years of age. The most common age is 47.
Line plots allow several features of the data to become more obvious.
For example, outliers, clusters, and gaps are apparent. Outliers are data points whose values are significantly larger or smaller than other values, such as the ages of 30, and 58. Clusters are isolated groups of points, such as the ages of 46 through 50. Gaps are large spaces between points, such as 41 and 45.
