These values can be used together to give an idea of what is typical in the population. The most common measure of variation, or spread, is the standard deviation. 2. The decision of the best measure of center depends on several factors. What is the denominator in the calculation of population standard deviation for a data set with . Using a table can help keep track of your computations for the standard deviation: Assuming this data represents a population, we will add the squared deviations, divide by 10, the number of data values, and compute the square root: \[\sqrt{\dfrac{25+25+25+25+25+25+25+25+25+25}{10}}=\sqrt{\dfrac{250}{10}}=5 \nonumber \].
