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 line of best fit represent in a scatter plot?

Back

A line of best fit is a straight line that best represents the data on a scatter plot, indicating the trend of the data points.

Front

What is correlation in the context of scatter plots?

Back

Correlation refers to the relationship between two variables, indicating how one variable may change in relation to another.

Front

What are the types of correlation?

Back

The types of correlation are positive correlation, negative correlation, and no correlation.

Front

What does 'no association' mean in a scatter plot?

Back

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

Front

How can you determine the line of best fit visually?

Back

The line of best fit can be determined visually by drawing a line that best represents the trend of the data points, minimizing the distance from the points to the line.

Front

What is the purpose of analyzing a scatter plot?

Back

The purpose of analyzing a scatter plot is to identify relationships, trends, and patterns between two variables.

Front

What does it mean if a scatter plot has a strong correlation?

Back

A strong correlation means that the data points are closely clustered around the line of best fit, indicating a strong relationship between the variables.
