Notes and assignment on the measures of center (mean, median, and mode) and variation (range and standard deviation). If the data follows a normal distribution, this means that the data points are equally distributed on each side of the mean. In addition to the mean and the median, there is one other common measurement of the "typical" value of a data set: the mode. If we are unsure whether the data set is a sample or a population, we will usually assume it is a sample, and we will round answers to one more decimal place than the original data as we have done above.
