Scatter Plots

Front

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 it mean to identify clusters in a scatter plot?

Back

Identifying clusters means finding groups of data points that are close together in the scatter plot, indicating a potential relationship or pattern.

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, often lying far away from the main cluster of data.

Front

What does a positive slope indicate in a scatter plot?

Back

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

Front

What does a negative slope indicate in a scatter plot?

Back

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

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 of the data.

Front

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

Back

You can determine if a line of best fit is accurate by checking how closely the data points cluster around the line.

Front

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

Back

No association means that there is no discernible pattern or relationship between the two variables being plotted.

Front

How do you find the coordinates of an outlier?

Back

The coordinates of an outlier are found by identifying the data point that lies farthest from the main cluster of points on the scatter plot.

Front

What is the significance of clusters in data analysis?

Back

Clusters can indicate trends, patterns, or groupings in data that may warrant further investigation.
