Scatterplot Predictions

Front

What is a scatterplot?

Back

A scatterplot 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 scatterplot?

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 scatterplot?

Back

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

Front

What does 'no correlation' mean in the context of a scatterplot?

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 linear relationship in a scatterplot?

Back

A linear relationship is when the data points form a straight line, indicating a consistent rate of change between the two variables.

Front

What is a non-linear relationship in a scatterplot?

Back

A non-linear relationship is when the data points do not form a straight line, indicating that the rate of change between the variables varies.

Front

How can you identify a positive correlation on a scatterplot?

Back

A positive correlation can be identified when the data points slope upwards from left to right.

Front

How can you identify a negative correlation on a scatterplot?

Back

A negative correlation can be identified when the data points slope downwards from left to right.

Front

What does it mean if a scatterplot 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 purpose of using scatterplots in data analysis?

Back

Scatterplots are used to visually assess the relationship between two variables and to identify trends, patterns, or correlations.
