Scatter Plots

Front

What is a scatter plot?

Back

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

Front

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

Back

The x-axis typically represents the independent variable, which is the variable that is manipulated or changed.

Front

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

Back

The y-axis typically represents the dependent variable, which is the variable that is measured or observed.

Front

What is a positive association in a scatter plot?

Back

A positive association means that as one variable increases, the other variable also increases, resulting in an upward trend.

Front

What is a negative association in a scatter plot?

Back

A negative association means that as one variable increases, the other variable decreases, resulting in a downward trend.

Front

What does no correlation mean in a scatter plot?

Back

No correlation means there is no apparent relationship between the two variables, and the data points do not show any clear trend.

Front

How can you identify the trend in a scatter plot?

Back

The trend can be identified by observing the overall direction of the data points; whether they slope upwards, downwards, or remain scattered.

Front

What is a trend line in a scatter plot?

Back

A trend line is a straight line that best represents the data points in a scatter plot, showing the general direction of the data.

Front

How can you use a scatter plot to make predictions?

Back

You can use a scatter plot to make predictions by extending the trend line to estimate values for the dependent variable based on the independent variable.

Front

What is the purpose of using scatter plots?

Back

Scatter plots are used to visually represent the relationship between two variables, helping to identify patterns, trends, and correlations.
