Chapter 2 Continued: Example: An analyst of trail derailments showed that (A) 23 derailments are caused by bad tracks. (B) 9 are caused by faulty equipment (C)12 are caused by human error (D)6 are caused by other causes Construct the frequency table: Category Frequency Relative frequency A. Derailment 23 .46 (46%) B. Faulty Eq. 9 .18 (18%) C. Human Err. 12 .24 (24%) D. Other 6 .06 (6%) Sum  50 1 (100%) How to construct the bar graph: 25 20 15 Frequesncy 10 5 0 derailment faulty equipment human erroother Categories How to construct the relative frequency bar graph: 0.45 0.4 0.35 0.3 0.25 0.2 0.15 RELATIVE Frequency 0.1 0.05 0 Categories How to construct a pie chart: 1. Always use a 2-dimentional circle for pie charts and NO other shape. - an ellpse will cause the sectors to be distorted depending on their placement. 2. Take each relative frequency for the different categories and then multiply them by 360 to get the proper angle
