Math diagram with an array of dots Crossword Clue

 The math diagram with an array of dots is a scatter plot.

A scatter plot is a type of graph that uses dots to represent data points. The dots are plotted on a coordinate plane, with the x-axis representing one variable and the y-axis representing another variable.

Scatter plots are used to show the relationship between two variables. For example, a scatter plot could be used to show the relationship between height and weight, or between temperature and rainfall.

Scatter plots can be used to identify trends and patterns in data. For example, a scatter plot could be used to identify a trend of increasing height with increasing weight, or a trend of decreasing rainfall with decreasing temperature.

Scatter plots can also be used to make predictions. For example, a scatter plot could be used to predict a person's weight based on their height, or to predict the amount of rainfall on a given day based on the temperature.

The dots on the scatter plot represent the height and weight of a group of people. The trend line shows the general trend of the data, which is that taller people tend to weigh more.

Scatter plots are a useful tool for analyzing data and making predictions. They are used in a variety of fields, including science, engineering, business, and economics.
