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 negative linear relationship in a scatterplot indicate?

Back

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

Front

What does a positive linear relationship in a scatterplot indicate?

Back

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

Front

How can you predict a value using a scatterplot?

Back

You can predict a value by finding the corresponding point on the scatterplot that aligns with the given value of one variable.

Front

What is the purpose of using scatterplots in data analysis?

Back

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

Front

What does it mean if there is no apparent association in a scatterplot?

Back

No apparent association means that there is no clear pattern or relationship between the two variables being plotted.

Front

How do you identify a linear association in a scatterplot?

Back

A linear association can be identified if the points in the scatterplot form a straight line or a pattern that resembles a straight line.

Front

What is the significance of the slope in a linear relationship?

Back

The slope indicates the rate of change between the two variables; a positive slope means both variables increase together, while a negative slope means one variable decreases as the other increases.

Front

What is the role of the x-axis and y-axis in a scatterplot?

Back

The x-axis typically represents the independent variable, while the y-axis represents the dependent variable.

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.
