scatterplots basics 1

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 in a scatterplot indicate?

Back

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

Front

What does a negative correlation in a scatterplot indicate?

Back

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

Front

What does no correlation mean in a scatterplot?

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 a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatterplot, showing the general direction of the data points.

Front

How can you identify a positive correlation in 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 in a scatterplot?

Back

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

Front

What is the purpose of a scatterplot?

Back

The purpose of a scatterplot is to visually display the relationship between two variables and to identify any patterns or trends.

Front

What does it mean if the points on a scatterplot are tightly clustered around the line of best fit?

Back

If the points are tightly clustered around the line of best fit, it indicates a strong correlation between the two variables.

Front

What does it mean if the points on a scatterplot are widely scattered?

Back

If the points are widely scattered, it indicates a weak correlation between the two variables.
