The appropriate measure of central tendency for age is the median which is 37 years of age, the mean which is equivalent to the average of 38 years of age, and the mode which cannot be derived from this data because there are no repetitive numbers. The range is 38, which is the difference between the maximum and minimum in this age data. The first quartile (25th percentile) is 29.75, the second quartile (the median) is 37, and the third quartile (75th percentile) is 46. The interquartile range is 16.25.

The appropriate measure of central tendency and variability for the gender cannot be determined because the variable measured for this data is qualitative.
