What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two variables by displaying data points on a two-dimensional grid.

Front

What does the line of fit represent in a scatter plot?

Back

The line of fit represents the general trend of the data points, showing how one variable is related to another.

Front

How do you draw a best line of fit?

Back

To draw a best line of fit, visually estimate a straight line that has roughly an equal number of data points above and below it.

Front

What is the slope of a line?

Back

The slope of a line indicates how steep the line is and the direction it goes; it is calculated as the change in y over the change in x.

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis, indicating the value of y when x is zero.

Front

What does the equation y = mx + b represent?

Back

The equation y = mx + b represents a linear equation where m is the slope and b is the y-intercept.

Front

What is a sample space in probability?

Back

A sample space is a list of all possible outcomes of an event.

Front

How can you make conjectures using a line of fit?

Back

You can make conjectures by analyzing the slope and y-intercept of the line of fit to predict relationships between variables.

Front

What does it mean to identify a linear equation from data in a table?

Back

Identifying a linear equation from data in a table means finding a mathematical equation that describes the relationship between the data points.

Front

What is the purpose of analyzing a scatter plot?

Back

The purpose of analyzing a scatter plot is to understand the relationship between two variables and to make predictions based on that relationship.
