    To use statistics the researcher must determine the standard deviation, mean and variance. He will need the following to calculate the mean:

    1. The IQ score range and the frequency of the range.

    To calculate the standard deviation and mean:

    1. Need the mean and frequency of the IQ scores

    Therefore the 4 things needed is:

    1. IQ range

    2. Frequency
