Dot Plots

A dot plot is a statistical chart that consists of dots plotted above a number line, representing the frequency of data points.

The mode is the value that appears most frequently in a data set.

A dot plot is skewed left if the tail on the left side is longer or fatter than the right side, indicating that more data points are concentrated on the higher end.

A dot plot is skewed right if the tail on the right side is longer or fatter than the left side, indicating that more data points are concentrated on the lower end.

To find the median, arrange the data points in order and identify the middle value. If there is an even number of data points, average the two middle values.

The mean is the average of all data points, while the median is the middle value when the data points are arranged in order.

Dot plots are used to visualize the distribution of data points and to identify patterns, trends, and outliers.

Count the number of dots in the dot plot; each dot represents one data point.

If no number repeats in a data set, it is said to have no mode.

The median provides a measure of central tendency that is not affected by extreme values or outliers.
