Building cumulative frequency tables, and reading medians, quartiles and box plots from the graphs.
Author note — to cover (Higher)
- Fluency — completing running totals for a cumulative frequency table, every total exact, and single-choice questions picking the plotting point at the upper class boundary (4 questions).
- Reading the curve — medians, quartiles and how many values lie above a given point, from stated curve readings at whole-number gridline values (4 questions).
- Box plots — the five values, range and interquartile range from stated box plot values, catching the box width read as the range (4 questions).
