What is meant by the terms medium, mean and mode in tests and measurements?
It’s “median,” rather than “medium.” These are three measures of what statisticians call “central tendency,” or the tendency of some types of measurements to cluster around the center of a range or the most frequently occurring case. The median is the number at which half the cases are greater and half the cases are less. It is also called the 50th percentile. The mean is just the statistical term for the arithmetic average; that is, the sum of all cases divided by the number of cases. The mode is the most frequently occurring, or most typical case. There are formulas for each of these measures. Grab any basic statistics textbook and check the index and the appendixes. Good luck!
