3.5 Scatterplots Review #2

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.

What does the x-axis typically represent in a scatterplot?

Back

The x-axis typically represents the independent variable, which is the variable that is manipulated or controlled.

Front

What does the y-axis typically represent in a scatterplot?

Back

The y-axis typically represents the dependent variable, which is the variable that is measured or observed.

How can you interpret the correlation in a scatterplot?

Back

A positive correlation means that as one variable increases, the other also increases. A negative correlation means that as one variable increases, the other decreases. No correlation means there is no apparent relationship.

What is the purpose of using a scatterplot?

Back

The purpose of using a scatterplot is to visually assess the relationship between two quantitative variables and to identify trends, patterns, or correlations.

Front

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

Back

If points are closely clustered together, it indicates a strong correlation between the two variables.

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

Back

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

Front

What is an outlier in a scatterplot?

Back

An outlier is a data point that lies significantly outside the range of the other data points, which can affect the overall interpretation of the scatterplot.

Front

How can you predict values using a scatterplot?

Back

You can predict values by finding the trend line (line of best fit) and using it to estimate the dependent variable based on the independent variable.

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.
