What does a positive correlation indicate in a scatter plot?

Back

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

Front

What does a negative correlation indicate in a scatter plot?

Back

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

Front

What does no correlation mean in a scatter plot?

Back

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

Front

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

Back

A positive correlation can be identified by a trend line that slopes upwards from left to right.

Front

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

Back

A negative correlation can be identified by a trend line that slopes downwards from left to right.

What is a trend line in a scatter plot?

Back

A trend line is a straight line that best represents the data points in a scatter plot, showing the general direction of the relationship between the variables.

Front

How do you use a trend line to make predictions?

Back

You can use a trend line to predict the value of one variable based on the value of another by finding the corresponding point on the line.

Front

What is the purpose of analyzing scatter plots?

Back

The purpose of analyzing scatter plots is to understand the relationship between two variables and to make predictions based on that relationship.

Front

What is the difference between correlation and causation?

Back

Correlation indicates a relationship between two variables, while causation indicates that one variable directly affects the other.
