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 a positive correlation indicate in a scatter plot?

Back

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

Front

What does a negative correlation indicate in a scatter plot?

Back

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

Front

What is a cluster in a scatter plot?

Back

A cluster is a group of data points that are closely packed together in a certain area of the graph.

Front

What is a gap in a scatter plot?

Back

A gap is an area in the scatter plot where there are no data points, indicating a lack of observations in that range.

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.

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 does a strong positive correlation look like on a scatter plot?

Back

A strong positive correlation appears as data points that are closely clustered around an upward-sloping line.

Front

What does a weak positive correlation look like on a scatter plot?

Back

A weak positive correlation appears as data points that are more spread out but still show a general upward trend.

Front

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

Back

A strong negative correlation appears as data points that are closely clustered around a downward-sloping line.
