Well first we need to determine what each choices ( mean, median, mode, interquartile range) means.
Mean- average of a set of numbers
Median - middle number of a set of numbers
Mode- number that appears the most in a set of numbers
Interquartile range- find median of set of numbers and separate the set into 3 equal sections total. Subtract the 3rd section from the 1st section. So you can find the range or span of numbers.
