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 in a scatter plot indicate?

Back

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

Front

What does a negative correlation in a scatter plot indicate?

Back

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

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 do not affect the other.

Front

What is the y-axis in a scatter plot?

Back

The y-axis represents the dependent variable, which is the variable being measured or affected.

Front

What is the x-axis in a scatter plot?

Back

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

Front

How can you identify a trend in a scatter plot?

Back

A trend can be identified by observing the overall direction of the data points; they may form a line or curve.

Front

What does it mean if a scatter plot shows 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

How can outliers affect a scatter plot?

Back

Outliers can skew the interpretation of the data, making it difficult to identify the true relationship between the variables.

Front

What is the purpose of using scatter plots?

Back

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