A researcher measures the IQ scores of a group of college students. What four things will the researcher use statistics for

1. IQ range

2. Frequency

3. Mean

4. Standard deviation and variance

Step-by-step explanation:

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

3. Mean

4. Standard deviation and variance
