The dot plot visually represents the lengths of seven aliens' big toes, revealing a central cluster around 16-17 cm. The outlier at 18 cm contributes to a range of 3 cm, while the median is 16.5 cm.
The data points in the image represent the lengths of the big toes of seven aliens, in centimeters. The lengths are:
18 cm
16 cm
17 cm
17 cm
16 cm
15 cm
16 cm
The image also shows a dot plot of the data. A dot plot is a way of displaying data visually, where each data point is represented by a dot on a graph. The horizontal axis of the graph shows the values of the data, and the vertical axis shows the number of times each value occurs.
In the dot plot, the dots are all clustered around the middle of the graph, between 16 cm and 17 cm. This means that most of the aliens have big toes that are about the same size. There is one outlier, with a big toe that is 18 cm long.
The range of the data is 3 cm, from 15 cm to 18 cm. The median is 16.5 cm, which means that half of the aliens have big toes that are shorter than 16.5 cm and half have big toes that are longer.
