Scatter Plot & Association

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 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 correlation?

Back

Correlation is a statistical measure that describes the extent to which two variables change together.

Front

What is a strong correlation?

Back

A strong correlation means that the data points in a scatter plot are closely clustered around a line, indicating a clear relationship between the variables.

Front

What is a weak correlation?

Back

A weak correlation means that the data points in a scatter plot are more spread out, indicating a less clear relationship between the variables.

Front

What is no correlation?

Back

No correlation means that there is no discernible relationship between the two variables, and the data points do not follow any pattern.

Front

What is an outlier in a scatter plot?

Back

An outlier is a data point that is significantly different from other observations in the dataset, often appearing far away from the trend of the other points.

Front

How can you identify an outlier in a scatter plot?

Back

An outlier can be identified by looking for points that lie far away from the cluster of other points in the scatter plot.

Front

What does a linear relationship in a scatter plot look like?

Back

A linear relationship appears as a straight line, indicating a consistent rate of change between the two variables.
