Document Summary
Allow researchers to arrange data visually to display meaning and to help in understanding the sample characteristics and variables under study. In some studies, descriptive statistics may be the only results sought from statistical analysis. Reduce data to manageable proportions by summarizing them: Shows relative ranking of objects; numbers assigned to each category can be compared, and a member of a higher category is said to have more of a certain attribute than one in a lower category. Shows rankings of events or objects on a scale with equal intervals between the numbers. Shows rankings of events or objects on scales with equal intervals and absolute zeros. Highest level of measurement usually only achieved in physical sciences. Summarizes the occurrences of events under study; tallies the frequency of events. Cohort groups are sometimes created to investigate the frequencies of certain data. Each measure has specific uses and is most appropriate to select types of distribution and measurement.
