Statistics
Take fair samples, sum up data with numbers and charts, and compare groups.
Learn why some samples mislead and how to take a fair one. Find averages from frequency tables, draw cumulative frequency graphs, box plots and histograms, read scatter graphs and time series, and spot a graph or an average that does not tell the truth.

For parents and teachers
For learners who can find the mean, median and range of a short list and read a bar chart. In many schools this fits teenagers of about 14 to 16, and adults who want to read statistics in the news with more care can start here too. Each chapter takes one or two sessions. A learner can work alone: every exercise has its answer and the reason for it. Each chapter also has a short page for the adult, with three questions to ask.
