Match the word to the correct definition. 

Causation 

 y tends to DECREASE as x INCREASES

No Correlation 

a number from -1 to 1 that measures how well a line fits the set of data plotted on the scatter plot (denoted by r)

Negative Correlation 

means that one thing will cause the other 

Scatter Plot 

y tends to INCREASE as x INCREASES 

Line of Best Fit 

A statistical way to measure the relationshp between two sets of data.  It means that both things are observed at the same time. 

Residual Value 

often used to present bivariate quantitative data.  Each variable is represented on an axis and the axes are labeled accordingly. 

Correlation Coefficient 

a straight line on a scatter plot that comes closest to all the dots on the graph. 

Correlation 

x and y seem to have NO relationship, or the data shows no pattern 

Positive Correlation 

the actual value minus the predicted value

Match the correlation coefficient to each picture. 

-0.5, weak negative correlation 

0.8, moderately strong positive correlation

1, strong positive correlation 

-0.8, moderately strong negative correlation 

-1, strong negative correlation 

0, no correlation 

0.5, weak positive correlation 

No Correlation

Mr. Jones gave a math test to all the students in the school. He made the discovery that the taller students did better than the shorter ones. His causation statement was: AS YOUR HEIGHT INCREASE, SO DOES YOUR MATH ABILITY. Is this causation correct?

Yes
