Scatter Plot Intro

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 strong positive correlation indicate?

Back

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

Front

What does a strong negative correlation indicate?

Back

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

Front

What is no correlation?

Back

No correlation means there is no discernible relationship between the two variables; changes in one do not affect the other.

Front

What is a positive correlation?

Back

A positive correlation is when two variables move in the same direction; as one increases, the other also increases.

Front

What is a negative correlation?

Back

A negative correlation is when two variables move in opposite directions; as one increases, the other decreases.

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 you identify a strong correlation in a scatter plot?

Back

A strong correlation is identified by data points that are closely clustered around a straight line, either positively or negatively.

Front

What is the significance of outliers in a scatter plot?

Back

Outliers are data points that fall far from the trend of the rest of the data; they can affect the correlation and interpretation of the data.

Front

What is the purpose of using scatter plots?

Back

Scatter plots are used to visually represent the relationship between two variables, making it easier to identify trends, correlations, and outliers.
