8.22 Key Features of 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 a positive linear relationship in a scatter plot indicate?

Back

A positive linear relationship indicates that as one variable increases, the other variable also increases.

Front

What does a negative linear relationship in a scatter plot indicate?

Back

A negative linear relationship indicates that as one variable increases, the other variable decreases.

Front

What is an outlier in a scatter plot?

Back

An outlier is a data point that is significantly different from other points in the dataset, often appearing far away from the main cluster of data.

Front

How can you identify gaps in a scatter plot?

Back

Gaps in a scatter plot can be identified by looking for ranges of x-values where there are no data points.

Front

What does it mean if there are no significant gaps in a scatter plot?

Back

It means that the data points are closely packed together without large intervals of missing values.

Front

What is the purpose of analyzing scatter plots?

Back

Analyzing scatter plots helps to understand the relationship between two variables, identify trends, and detect outliers.

Front

How do you determine the amount of a variable at a specific point in a scatter plot?

Back

To determine the amount of a variable at a specific point, locate the x-value on the horizontal axis and find the corresponding y-value on the vertical axis.

Front

What is a non-linear relationship in a scatter plot?

Back

A non-linear relationship occurs when the data points do not form a straight line, indicating a more complex relationship between the variables.

Front

What does it mean if a scatter plot shows no relationship?

Back

It means that changes in one variable do not correspond to changes in the other variable, and the data points are scattered randomly.
