Correlation Coefficient Data

The table gives the number of hours spent studying for an algebra exam (x) and the final exam (y). Determine the correlation of the data.

• Weak positive

• Weak Negative

• Strong Positive

• Strong Negative

If the correlation coefficient, r, of a data set is r = -0.95. What type of correlation does the data have?

• Strong Positive

• Strong negative

• Weak Postive

• Weak Negative

• No correlation

Determine the correlation of the points on the scatterplot.

• Positive Correlation

• Negative Correlation

• No Correlation

• Zero Correlation

Determine the correlation of the points on the scatterplot.

• Positive Correlation

• Negative Correlation

• No Correlation

• Zero Correlation

Find the correlation coefficients of the following data

• Table 1

• Table 3

• Table 2

Correlation coefficients are:

• A point that does not fit the overall pattern.

• A histogram.

• A numerical measure of the direction and strength of a linear association.

• A graphical display.

Determine the correlation coefficient for the data in the table. Round to the nearest hundredth.

A study compared the number of cars a person owns and that person’s average yearly salary. It was determined that the relationship between these two quantities was linear and the correlation was 0.37. Which conclusion can be made on the findings of this study?

• There was a weak relationship.

• There was a strong relationship.

• There was no relationship.

• Unpredictable.
