What is a scatterplot?

Back

A scatterplot is a graph that shows the relationship between two quantitative variables by displaying data points on a two-dimensional axis.

What does the line of best fit represent in a scatterplot?

Back

The line of best fit is a straight line that best represents the data on a scatterplot, indicating the general direction of the relationship between the variables.

What is correlation in the context of scatterplots?

Back

Correlation refers to the strength and direction of a relationship between two variables, which can be positive, negative, or none.

What does a positive correlation look like on a scatterplot?

Back

A positive correlation is indicated by data points that trend upwards from left to right, meaning as one variable increases, the other variable also increases.

What does a negative correlation look like on a scatterplot?

Back

A negative correlation is indicated by data points that trend downwards from left to right, meaning as one variable increases, the other variable decreases.

What does it mean if there is no correlation in a scatterplot?

Back

No correlation means there is no discernible relationship between the two variables, and the data points are scattered randomly.

How can you use a trend line to make predictions?

Back

A trend line can be used to estimate the value of one variable based on the value of another variable by extending the line beyond the existing data points.

Front

What is a linear correlation?

Back

A linear correlation is a relationship between two variables that can be represented by a straight line on a scatterplot.

Front

What is a non-linear correlation?

Back

A non-linear correlation is a relationship between two variables that cannot be accurately represented by a straight line, often showing a curved pattern.

Front

How do you identify the line of best fit on a scatterplot?

Back

The line of best fit is identified by visually assessing which line minimizes the distance between itself and all the data points.
