Interpret & Predict Scatterplots

Front

What is a scatterplot?

Back

A scatterplot is a graphical representation of two variables, showing the relationship between them using points on a Cartesian plane.

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 is the line of best fit?

Back

The 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 estimate values using a scatterplot?

Back

You can estimate values by locating the corresponding point on the line of best fit for a given input value.

Front

What does it mean if points on a scatterplot are widely spread out?

Back

Widely spread out points indicate a weak correlation between the two variables.

Front

What does it mean if points on a scatterplot are closely clustered?

Back

Closely clustered points indicate a strong correlation between the two variables.

Front

What is the purpose of using a scatterplot in data analysis?

Back

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

Front

What is an outlier in a scatterplot?

Back

An outlier is a data point that lies significantly outside the range of the other points, potentially indicating an anomaly.

Front

How can you determine the strength of a correlation from a scatterplot?

Back

The strength of a correlation can be determined by how closely the points cluster around the line of best fit.
