Construct and Interpret 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 correlation indicate in a scatter plot?

Back

A positive correlation indicates that as one variable increases, the other variable also tends to increase.

Front

What does a negative correlation indicate in a scatter plot?

Back

A negative correlation indicates that as one variable increases, the other variable tends to decrease.

Front

What does no correlation mean in a scatter plot?

Back

No correlation means there is no apparent relationship between the two variables; changes in one variable do not predict changes in the other.

Front

What is an outlier in a scatter plot?

Back

An outlier is a data point that differs significantly from other observations in the dataset, often appearing far away from the trend of the data.

Front

How can you identify an outlier in a scatter plot?

Back

An outlier can be identified by looking for points that are distant from the overall pattern of the data.

Front

What is a gap in a scatter plot?

Back

A gap is a range of values on the x-axis where there are no data points, indicating a lack of observations in that range.

Front

How do you interpret a scatter plot with a nonlinear association?

Back

A nonlinear association means that the relationship between the variables does not follow a straight line; it may curve or change direction.

Front

What is the purpose of creating a scatter plot?

Back

The purpose of creating a scatter plot is to visually represent the relationship between two variables and to identify patterns, trends, or correlations.

Front

What does it mean if a scatter plot shows a strong correlation?

Back

A strong correlation means that the data points closely follow a clear trend, indicating a strong relationship between the two variables.
