Document Summary

Statistics is a way to get information from data. Statistics is a tool for creating new understanding from a set of numbers. Descriptive statistics deals with methods of organizing, summarizing, and presenting data in a convenient and informative way. One form of descriptive statistics uses graphical techniques, which allow statistics practitioners to present data in ways that make it easy for the reader to extract useful information. Another form of descriptive statistics uses numerical techniques to summarize data. The mean and median are popular numerical techniques to describe the location of the data. The range, variance, and standard deviation measure the variability of the data. The actual method used depends on what information we would like to extract. Statistical inference is the process of making an estimate, prediction, or decision about a population based on a sample. We use statistics to make inferences about parameters. A sample is a set of data drawn from the population.
