Exploring Relationships

Front

What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two variables by displaying data points on a two-dimensional axis.

What does a linear relationship in a scatter plot indicate?

Back

A linear relationship indicates that as one variable increases or decreases, the other variable does so in a consistent manner, forming a straight line when graphed.

Front

What is correlation?

Back

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

Front

What are the types of correlation?

Back

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

Front

What is a positive correlation?

Back

A positive correlation occurs when an increase in one variable leads to an increase in another variable.

Front

What is a negative correlation?

Back

A negative correlation occurs when an increase in one variable leads to a decrease in another variable.

Front

What is no correlation?

Back

No correlation means that there is no predictable relationship between the two variables.

Front

What is an outlier in a scatter plot?

Back

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

Front

What is a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatter plot, showing the general direction of the data.

Front

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

Back

A linear relationship can be identified if the data points roughly form a straight line.
