Question

A median, mode, frequency, and range are examples of statistical analysis techniques for which level of measurement?

Answer 1

The terms mean, median and mode are the common used measure of central tendency of a large data set. Central tendency is most commonly referred to as numerical central of the data set. When working with a large data set, it can be useful to represent the entire data set with a single value that describes the "middle" or "average" value of the entire set. In statistics, that single value is called the central tendency and mean, median and mode are all ways to describe it. The mode of a data set may have more than one value because the mode just measures the most common data value.

For example the data set below has a mode of 2:

1,2,2,2,3,3

But this data set has a mode of both 2 and 3:

1,2,2,3,3,4
