  1. Descriptive Statistics Method of collecting, organizing, displaying, and drawing conclusion of data

  2. Collecting and Organizing Organizing/Processing, Calculating DATA measured (mm scale) (collect) Variables Numerical Categorical Continuous Discrete Dichotomous Polychotomous Interval Ratio scale Nominal Ordinal scale

  3. DATA SUMMARY (calculation) • Mean - • Median – middle most (50% are higher and 50% are lower) • Mode – most repeated • Measure of Variability • Range = Mx-Mn • Variance s2= • SD • Proportion

  4. DATA PRESENTATION (displaying) • Table (number, title, column and raw labels, body of data, total, source) – self explain. • Graph: • line graph – numerical variables • Scatter – numerical variables • bar graph – categorical variables • Histogram – continuous variables • pie graph – proportion of a whole with a few elements, categorical variables

  5. Descriptive Statistics
