  • 1

    What is the Product Moment Correlation Coefficient (r)

    A measure of the strength and type of linear correlation between two variables

  • 2

    Which Values can the Product Moment Correlation Coefficient take

    Any values between -1 and 1, including -1 and 1

  • 3

    If r = 1 or -1,

    There is a perfect positive or negative linear correlation (all points lie on a straight line)

  • 4

    If r = 0,

    There is no linear correlation (although there may be a non-linear relationship)

  • 5

    The nearer r is to 1 or -1,

    The stronger the positive or negative correlation

  • 6

    How is the Product Moment Correlation Coefficient Calculated

    Enter 'Menu", "6", then "2" into your calculator, Input the corresponding x and y values, Enter "Option", then "4" into your calculator, Take the given value for r

  • 7

    Which values are Discarded when calculating 'r'

    Any value that is "n/a", as well as the corresponding x or y value

  • 8

    How are "tr" values taken

    As equal to zero
