Worksheet functions are AVERAGE(data_range) for arithmetic mean, MEDIAN for
median, MODE for mode, and STDEV for standard deviation.

Of course, median is appropriate for ordinal, interval, and ratio data, and
mode is appropriate for nominal, ordinal, interval, and ratio data.

data that are interval or ratio in measurement, and in standard deviation
for
the data that are interval or ratio in measurement.
