Scatterplot Association

Front

What is a scatterplot?

Back

A scatterplot is a graph that displays values for typically two variables for a set of data. Each point represents an observation in the dataset.

Front

What does a positive association in a scatterplot indicate?

Back

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

Front

What does a negative association in a scatterplot indicate?

Back

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

Front

What does no association mean in a scatterplot?

Back

No association means that there is no discernible relationship between the two variables; changes in one do not affect 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 trend of the data.

Front

How can you determine if a line of best fit is accurate?

Back

An accurate line of best fit minimizes the distance between the line and all the data points, capturing the overall trend.

Front

What is correlation in the context of scatterplots?

Back

Correlation refers to the strength and direction of a relationship between two variables, which can be positive, negative, or none.

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

What does a correlation coefficient of +1 indicate?

Back

A correlation coefficient of +1 indicates a perfect positive correlation between two variables.

Front

What does a correlation coefficient of -1 indicate?

Back

A correlation coefficient of -1 indicates a perfect negative correlation between two variables.
