ScatterPlots

Front

What is a scatter plot?

Back

A scatter plot is a graphical representation of two variables, where each point represents an observation in the dataset, allowing for the visualization of relationships between the variables.

Front

What does a positive association in a scatter plot indicate?

Back

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

Front

What does a negative association in a scatter plot indicate?

Back

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

Front

What is a nonlinear association in a scatter plot?

Back

A nonlinear association occurs when the relationship between the two variables cannot be accurately represented by a straight line.

Front

What does 'no correlation' mean in the context of a scatter plot?

Back

No correlation means that there is no discernible relationship between the two variables; changes in one variable do not predict changes in the other.

Front

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

Back

A positive association can be identified by a pattern where points tend to rise from left to right.

Front

How can you identify a negative association in a scatter plot?

Back

A negative association can be identified by a pattern where points tend to fall from left to right.

Front

What is the purpose of using scatter plots in data analysis?

Back

Scatter plots are used to visually assess the relationship between two quantitative variables, helping to identify trends, correlations, and potential outliers.

Front

What is the significance of outliers in a scatter plot?

Back

Outliers are data points that deviate significantly from the overall pattern of the data, and they can influence the correlation and interpretation of the relationship.

Front

What does it mean if a scatter plot shows a cluster of points?

Back

A cluster of points indicates that there is a concentration of observations in a particular area of the plot, suggesting a potential relationship or commonality among those observations.
