Scatter Plots

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.

Front

What does it mean when points on a scatter plot trend upwards?

Back

It means that as one variable increases, the other variable also increases.

Front

What does it mean when points on a scatter plot trend downwards?

Back

It means that as one variable increases, the other variable decreases.

Front

What is the purpose of using a scatter plot?

Back

To visually represent the relationship between two sets of data and to identify trends or patterns.

Front

What is a positive correlation in a scatter plot?

Back

A positive correlation occurs when both variables increase together, resulting in an upward trend.

Front

What is a negative correlation in a scatter plot?

Back

A negative correlation occurs when one variable increases while the other decreases, resulting in a downward trend.

Front

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

Back

It means that there is no apparent relationship between the two variables, and the points are scattered randomly.

Front

How can you determine the strength of a correlation in a scatter plot?

Back

The strength of a correlation can be determined by how closely the points cluster around a line; a tighter cluster indicates a stronger correlation.

Front

What is the x-axis in a scatter plot?

Back

The x-axis is the horizontal line on a graph that typically represents the independent variable.

Front

What is the y-axis in a scatter plot?

Back

The y-axis is the vertical line on a graph that typically represents the dependent variable.
