Once the scales have been identified, then begins the drawing of the rectangles whose bases equal the class interval and whose heights are determined by the corresponding class frequencies. The markings on the horizontal scale can be the class limits, as in our example; the class boundaries; the class marks; or arbitrary key values. For easy readability, it is generally preferable to indicate the class limits, although the rectangles 52 Chapter 3: Summarizing Data Chapter 3: Summarizing Data 53 actually go from one class boundary to the next.
4. Variance for factor P is Vp = SSP/dfp 40 Chapter 2: Problem Solving Chapter 2: Problem Solving 41 5. Variance for total is VTotal = SSTotal/dfTotal Of note here is the fact that if only one repetition is collected for each trial, and all columns of the OA are used to evaluate factor effects, Verror (variance due to error) cannot be computed, as SSerror and dferror will be equal to 0. Verror = SSerror/dferror 6. A technique called pooling is often used to obtain an estimate of error variance, Verror.
50 Chapter 3: Summarizing Data Chapter 3: Summarizing Data 51 WHY HISTOGRAMS ARE USED Histograms are used because they help to summarize data and tell a story that would be lengthy and less effective in narrative form. Also, they are standardized in format and thus lend themselves to a high degree of communication between users. On the basis of a long history of experience in analyzing observations made about happenings in nature, activities of people, and machine operations, it has been found that repetitive operations yield slightly different results.
