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.

What does a positive slope indicate in a scatter plot?

Back

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

Front

What does a negative slope indicate in a scatter plot?

Back

A negative slope indicates that as one variable increases, the other variable decreases.

Front

What is an outlier in a scatter plot?

Back

An outlier is a data point that is significantly different from other data points, often lying far away from the main cluster.

Front

What does it mean if a scatter plot shows no association?

Back

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

Front

What is correlation in the context of scatter plots?

Back

Correlation refers to the strength and direction of a relationship between two variables, which can be positive, negative, or none.

Front

What is a strong positive correlation?

Back

A strong positive correlation means that the data points in a scatter plot are closely clustered together and rise together.

Front

What is a weak negative correlation?

Back

A weak negative correlation means that there is a slight downward trend in the data points, but they are more spread out.

Front

How can you identify an outlier in a scatter plot?

Back

An outlier can be identified as a point that is far removed from the general pattern of the other data points.

Front

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

Back

A strong negative correlation appears as a downward slope where data points are closely clustered.
