Scatter Plots

Front

What is a scatter plot?

Back

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

Front

What do the points on a scatter plot represent?

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 does it mean if the points on a scatter plot are closely clustered together?

Back

If the points are closely clustered together, it indicates a strong correlation between the two variables.

Front

What is the purpose of using a scatter plot?

Back

The purpose of using a scatter plot is to visually display the relationship between two quantitative variables.

Front

What is an outlier in a scatter plot?

Back

An outlier is a data point that lies far away from the other points in the scatter plot, indicating it may not fit the general trend.

Front

How can you determine the trend of data in a scatter plot?

Back

The trend of data can be determined by drawing a line of best fit that summarizes the direction of the data points.

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 overall trend.
