Scatter Plot Associations

Front

What is a scatter plot?

Back

A scatter plot is a graphical representation of two variables where each point represents an observation. It helps to visualize the relationship between the variables.

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 increases.

Front

What does a negative correlation indicate in a scatter plot?

Back

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

Front

What does no association mean in the context of a scatter plot?

Back

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

Front

How can you identify a positive correlation in a scatter plot?

Back

A positive correlation can be identified by a pattern where points slope upwards from left to right.

Front

How can you identify a negative correlation in a scatter plot?

Back

A negative correlation can be identified by a pattern where points slope downwards from left to right.

Front

What is the significance of the slope in a scatter plot?

Back

The slope indicates the direction and strength of the relationship between the two variables; a steeper slope indicates a stronger relationship.

Front

What is the purpose of using scatter plots in data analysis?

Back

Scatter plots are used to identify relationships, trends, and patterns between two quantitative variables.

Front

What does it mean if a scatter plot shows a cluster of points?

Back

A cluster of points indicates that there is a strong relationship between the two variables in that range.

Front

What is the role of outliers in a scatter plot?

Back

Outliers are points that fall far from the general pattern of the data and can significantly affect the correlation and interpretation of the relationship.
