What is a scatterplot?

Back

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

What does a positive linear relationship look like in a scatterplot?

Back

In a positive linear relationship, as one variable increases, the other variable also increases, resulting in a straight line that slopes upwards.

Front

What does a negative linear relationship look like in a scatterplot?

Back

In a negative linear relationship, as one variable increases, the other variable decreases, resulting in a straight line that slopes downwards.

Front

What does 'no relationship' mean in a scatterplot?

Back

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

Front

What is a trend line in a scatterplot?

Back

A trend line is a straight or curved line that represents the general direction of the data points in a scatterplot.

Front

How can you tell if a trend line is correctly placed?

Back

A correctly placed trend line should closely follow the pattern of the data points, minimizing the distance between the line and the points.

Front

What is an example of a positive non-linear relationship?

Back

An example of a positive non-linear relationship is the relationship between the amount of time studied and test scores, where scores increase at an increasing rate.

Front

What is an example of a negative non-linear relationship?

Back

An example of a negative non-linear relationship is the relationship between the speed of a car and the time taken to reach a destination, where faster speeds lead to shorter times but not in a straight line.

Front

What does it mean if a scatterplot shows a cluster of points?

Back

A cluster of points in a scatterplot indicates that there is a strong relationship between the two variables in that area.

Front

What is the purpose of using scatterplots?

Back

Scatterplots are used to visually represent the relationship between two variables, making it easier to identify trends, correlations, and outliers.
