Back

The points on a scatter plot represent individual data points, with one variable plotted along the x-axis and the other along the y-axis.

Front

How can you identify a positive correlation in a scatter plot?

Back

A positive correlation is identified when the points on the scatter plot trend upwards from left to right.

Front

What does a negative correlation look like on a scatter plot?

Back

A negative correlation is shown when the points on the scatter plot trend downwards from left to right.

Front

What does it mean if the points on a scatter plot are widely spread out?

Back

If the points are widely spread out, it indicates a weak correlation between the two variables.

Front

What is the purpose of a trend line in a scatter plot?

Back

A trend line is used to summarize the relationship between the variables and can help predict future values.

Front

What is an outlier in a scatter plot?

Back

An outlier is a data point that is significantly different from the other points in the scatter plot.

Front

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

Back

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

Front

What is the x-axis in a scatter plot?

Back

The x-axis is the horizontal axis that represents one of the variables being analyzed.

Front

What is the y-axis in a scatter plot?

Back

The y-axis is the vertical axis that represents the other variable being analyzed.
