A histogram table presents the letter-grade boundaries and the number of scores between the lowest bound and the current bound. The single most frequent score is the mode of the cell range of data. Moving Average Projects values in the forecast period, based on the average value of the variable over a specific number of preceding periods. You can use this procedure to forecast sales, inventory, or other trends. Random Number Generation Fills a range with independent random numbers drawn from one of several distributions.
Random variables have a variety of applications in statistical simulations.
One application of this procedure characterizes subjects in a population with a probability distribution. For example, you might use a normal distribution to characterize the population of individuals' heights, or you might use a Bernoulli distribution of two possible outcomes to characterize the population of coin-flip results. Rank and Percentile Produces a table that contains the ordinal and percentage rank of each value in a data set. You can use this procedure to analyze the relative standing of values in a data set. Regression Performs linear regression analysis.
