How Do You Calculate The Mean, Median, & Mode?
The mean, median and mode are measures of central tendency and may also be referred to collectively as types of averages. The term “mean” in the context of statistics refers specifically to the arithmetic mean since there are other types of means, such as the geometric mean or harmonic mean. The arithmetic mean is also frequently referred to as “the average” in common usage, although this is mathematically imprecise, since there are other types of averages. Define some statistical terms. All measures of central tendency are calculated from a collection of numbers known as a data set. Each member of a data set is also known as a data point. Determine the arithmetic mean of a data set. The arithmetic mean is defined as the sum of the data points divided by the number of data points. Thus, a data set consisting of 12, 15, 16 and 19 would have an arithmetic mean of (12 + 15 + 16 + 19)/4 = 62/4 = 15.5 Evaluate the median of a data set with an odd number of data points.
