Front

What is a scatter plot?

Back

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

What does the x-axis represent in a scatter plot?

Back

The x-axis represents the independent variable in a scatter plot.

Front

What does the y-axis represent in a scatter plot?

Back

The y-axis represents the dependent variable in a scatter plot.

Front

How do you determine if a relationship in a scatter plot is additive?

Back

A relationship is additive if the change in the y-value is constant for equal changes in the x-value.

Front

How do you determine if a relationship in a scatter plot is multiplicative?

Back

A relationship is multiplicative if the ratio of the y-value to the x-value is constant.

Front

What is the purpose of a trend line in a scatter plot?

Back

A trend line helps to visualize the general direction of the data points and can indicate the type of relationship between the variables.

Front

What does a positive correlation in a scatter plot indicate?

Back

A positive correlation indicates that as one variable increases, the other variable also tends to increase.

Front

What does a negative correlation in a scatter plot indicate?

Back

A negative correlation indicates that as one variable increases, the other variable tends to decrease.

Front

What is the formula for a linear relationship in a scatter plot?

Back

The formula for a linear relationship is typically written as y = mx + b, where m is the slope and b is the y-intercept.

Front

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

Back

The slope represents the rate of change of the dependent variable (y) with respect to the independent variable (x).
