approach to the most commonly used numeric and graphic methods for describing data. Methods are presented for summarizing data numerically‚ including presentation of data in tables and calculation of statistics for central tendency‚ variability‚ and distribution. Methods are also presented for displaying data graphically‚ including line graphs‚ bar graphs‚ histograms‚ and frequency polygons. The description and graphing of study data result in better analysis and presentation of data. © Index terms:
