Using the graphing calculator to determine the correlation coefficient for each data set. Which one has a bigger correlation coefficient?

• Set A

• Set B

• They are equal.

As shown in the table, a person's target heart rate during exercise changes as the person gets older. Use the graphing calculator to find the correlation coefficient (r).

• -0.999

• -0.664

• 0.998

• 1.503

What COULD be the approximate value of the correlation coefficient for the scatter plot?

• -.851

• -.162

• 0.211

• 0.905

Determine the correlation coefficient of the given data.

• - .5477

• .1770

• .8956

• - .9463

As shown in the table, a person's target heart rate during exercise changes as the person gets older. Find the correlation coefficient (r).

• -0.999

• -0.664

• 0.998

• 1.503

Using your graphing calculator determine the line of best fit and the correlation coefficient of the data in the table.

• y = 4.6x - 347

  r = .942

• y = 4.6x - 347

  r = .888

• y = 4.6x + 347

  r = .942

• y = 4.6x + 347

  r = .888
