Put simply, it is the value at the center of the sorted observations. It also calculates median, average, sum and other important statistical numbers like standard deviation. Values must be numeric and may be separated by commas, spaces or new-line. Small-sample estimates based on the formulas shown above will be calculated for all samples, irrespective of size. Click the Calculate! For example, certain measures like the mean are very sensitive to outliers, and therefore, when a sample has strong outliers or it is very skewed, the preferred measure of central tendency would be the median instead of the sample mean . This calculator uses two different formulas for calculating the median, depending on whether the number of observations is odd, or it is even: When the number of observations is odd the formula is: When the number of observations is even the formula is: Press the "Submit Data" button to perform the computation. 45 plus 1 is 46, then divide by 2 and we get 23. In statistics, the middle number of a set of data is called as the median. The uncertainty in a given random sample (namely that is expected that the proportion estimate, p̂, is a good, but not perfect, approximation for the true proportion p) can be summarized by saying that the estimate p̂ is normally distributed with mean p and variance p(1-p)/n. With millions of qualified respondents, SurveyMonkey Audience makes it easy to get survey responses from people around the world instantly, from almost anyone.
