| Stavka koja se može prevući | arrow_right_alt | Odgovarajuća stavka |
|---|---|---|
Line of Best Fit | arrow_right_alt | y tends to DECREASE as x INCREASES |
Positive Correlation | arrow_right_alt | 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) |
Correlation | arrow_right_alt | means that one thing will cause the other |
No Correlation | arrow_right_alt | y tends to INCREASE as x INCREASES |
Residual Value | arrow_right_alt | A statistical way to measure the relationshp between two sets of data. It means that both things are observed at the same time. |
Correlation Coefficient | arrow_right_alt | often used to present bivariate quantitative data. Each variable is represented on an axis and the axes are labeled accordingly. |
Scatter Plot | arrow_right_alt | a straight line on a scatter plot that comes closest to all the dots on the graph. |
Causation | arrow_right_alt | x and y seem to have NO relationship, or the data shows no pattern |
Negative Correlation | arrow_right_alt | the actual value minus the predicted value |
Match the correlation coefficient to each picture.

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?
