Scatterplot Predictions

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 correlation mean in a scatterplot?

Back

Correlation refers to the relationship between two variables in a scatterplot, indicating how one variable may change in relation to another.

Front

What are the types of correlation?

Back

The types of correlation are positive correlation, negative correlation, and no correlation.

Front

What does a positive correlation indicate?

Back

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

Front

What does a negative correlation indicate?

Back

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

Front

What does 'no correlation' mean?

Back

'No correlation' means that there is no discernible relationship between the two variables in the scatterplot.

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 do you determine if a line of best fit is accurate?

Back

A line of best fit is considered accurate if it closely follows the trend of the data points and minimizes the distance from the points to the line.

Front

What is an example of a positive linear association?

Back

An example of a positive linear association is the relationship between hours studied and test scores, where more study time generally leads to higher scores.

Front

What is an example of a negative linear association?

Back

An example of a negative linear association is the relationship between the amount of gas in a tank and the distance a car can travel, where less gas means less distance.
