Scatter Plots #1

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 correlation mean in a scatter plot?

Back

Correlation refers to the strength and direction of a linear relationship between two variables in a scatter plot.

Front

What is the difference between causation and correlation?

Back

Causation indicates that one event causes another, while correlation indicates a relationship between two events without implying cause.

Front

What are outliers in a scatter plot?

Back

Outliers are data points that differ significantly from other observations in a scatter plot, potentially indicating variability or errors.

Front

What does a strong positive correlation look like in a scatter plot?

Back

A strong positive correlation is represented by points that closely follow a straight line with a positive slope.

Front

What does a weak negative correlation indicate?

Back

A weak negative correlation indicates that as one variable increases, the other variable tends to decrease, but the relationship is not strong.

Front

How can you identify a linear relationship in a scatter plot?

Back

A linear relationship can be identified if the data points form a pattern that resembles a straight line.

Front

What is a nonlinear relationship?

Back

A nonlinear relationship is when the data points do not follow a straight line, indicating a more complex relationship between the variables.

Front

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

Back

No correlation means that there is no discernible relationship between the two variables, and the data points are scattered randomly.

Front

How do you determine if a scatter plot has outliers?

Back

Outliers can be determined by identifying points that are significantly distant from the overall pattern of the data.
