Dot Plots

A dot plot is a statistical chart that uses dots to represent the frequency of data points in a dataset.

To read a dot plot, count the number of dots above each value to determine how many times that value occurs in the dataset.

A skewed dot plot indicates that the data is not evenly distributed, with more values on one side than the other.

The median is the middle value when the data points are arranged in order.

The range is found by subtracting the smallest value from the largest value in the dataset.

The interquartile range is the difference between the first quartile (Q1) and the third quartile (Q3) in a dataset.

A symmetrical dot plot indicates that the data is evenly distributed around the center.

The mode is the value that appears most frequently in the dataset, represented by the highest stack of dots in the dot plot.

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

Outliers are data points that are significantly higher or lower than the rest of the data, often appearing as isolated dots.
