What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two quantitative variables by displaying data points on a two-dimensional axis.

Front

What does a positive correlation in a scatter plot indicate?

Back

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

Front

What does a negative correlation in a scatter plot indicate?

Back

A negative correlation indicates that as one variable increases, the other variable decreases.

Front

What is an outlier in a scatter plot?

Back

An outlier is a data point that differs significantly from other observations in the dataset.

Front

How can you identify an outlier in a scatter plot?

Back

An outlier can be identified as a point that is far away from the cluster of other points.

Front

What does it mean if there is no correlation in a scatter plot?

Back

No correlation means that there is no apparent relationship between the two variables being plotted.

Front

What is the purpose of a scatter plot?

Back

The purpose of a scatter plot is to visually display the relationship between two variables and to identify trends, correlations, or outliers.

Front

What does a gap in a scatter plot indicate?

Back

A gap in a scatter plot indicates a range of values where no data points are present.

Front

How can you determine the strength of a correlation in a scatter plot?

Back

The strength of a correlation can be determined by how closely the data points cluster around a line of best fit.

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 scatter plot, showing the trend of the data.
