What does the x-axis represent in a scatter plot?

Back

The x-axis typically represents the independent variable, which is the variable that is manipulated or changed.

Front

What does the y-axis represent in a scatter plot?

Back

The y-axis typically represents the dependent variable, which is the variable that is measured or observed.

Front

What is correlation in a scatter plot?

Back

Correlation describes the strength and direction of a relationship between two variables in a scatter plot.

Front

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

Back

A strong positive correlation is indicated by points that closely follow a straight line that slopes upwards from left to right.

Front

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

Back

A strong negative correlation is indicated by points that closely follow a straight line that slopes downwards from left to right.

Front

What is a weak correlation in a scatter plot?

Back

A weak correlation is indicated by points that are more spread out and do not follow a clear linear pattern.

Front

How can you predict a value using a scatter plot?

Back

You can predict a value by finding the corresponding point on the scatter plot that aligns with the given value on the x-axis.

Front

What does it mean if there is no correlation in a scatter plot?

Back

No correlation means that there is no apparent relationship between the two variables, and the points are scattered randomly.

Front

How can outliers affect a scatter plot?

Back

Outliers can skew the interpretation of the data, affecting the perceived correlation and overall trend.
