    The formula that is most often used is:

    P = (c + 0.5r) / N x 100

    c : count of scores that are *lower*

    r : number of scores that have the same value as the score of interest

    N : total number of scores

    37:

    c : lower scores (5)

    r : repeated (1)

    N : total scores (23)

    = (5 + 1*0.5)/23 * 100

    = 5.5/23 * 100

    ≈ 23.9

    24th percentile

    47:

    c : lower scores (8)

    r : repeated (2)

    N : total scores (23)

    = (8 + 2*0.5) / 23 * 100

    = 9/23 * 100

    ≈ 39.1

    39th percentile

    63:

    c : lower scores (15)

    r : repeated (1)

    N : total scores (23)

    = (15 + 1*0.5) / 23 * 100

    = 15.5 / 23 * 100

    ≈ 67.4

    67th percentile

    There are 23 data points.

    37 is the 6th data point, so it is the:

    6/23 = 0.2609

    26th percentile
