Front

What is a scatterplot?

Back

A scatterplot is a graphical representation that displays the relationship between two quantitative variables, showing how much one variable is affected by another.

Front

What does a positive linear association in a scatterplot indicate?

Back

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

Front

What does a negative linear association in a scatterplot indicate?

Back

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

Front

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

Back

It means that there is no clear relationship between the two variables being plotted.

Front

How can you predict values using a scatterplot?

Back

You can predict values by observing the trend in the scatterplot and estimating the value based on the pattern of the data points.

Front

What is the purpose of using scatterplots in data analysis?

Back

Scatterplots are used to visually assess the relationship between two variables, helping to identify trends, correlations, and potential outliers.

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 steeper slope means a stronger relationship.

Front

What does it mean if a scatterplot shows a non-linear association?

Back

A non-linear association means that the relationship between the variables does not follow a straight line, indicating a more complex relationship.

Front

What is the difference between correlation and causation?

Back

Correlation indicates a relationship between two variables, while causation implies that one variable directly affects the other.

Front

How do you identify outliers in a scatterplot?

Back

Outliers are data points that fall far away from the general trend of the other points in the scatterplot.
