ABSTRACT
Descriptive stats are simply numbers that describe our quantitative findings in a visual nutshell through tables, charts, and graphs. Descriptive analysis can consist of univariate, bivariate analysis, and multivariate analysis. Three measure of central tendency (CT) describes the types of sample: mode, median, and mean. Variability is measured in three different ways: index of dispersion, range, and standard deviation. Frequency tables often include other basic descriptive stats, such as central tendency and variability. Bar charts are commonly used to depict responses to ordinal LOM variables. Histograms are like bar charts but commonly used to depict responses to interval or ratio LOM variables. A mode, generally used to describe CT for nominal LOM variables, reflects the most frequent response category. A median, generally used to describe CT for ordinal, interval, and ratio LOM variables. A mean is like a mathematical average, and it's best used to describe CT for interval and ratio LOM variables.
