Can you add up the number of students in your classroom? Can you tell which of two test scores is the larger? Can you programme a video or DVD recording using a 24-hour clock? If so, then this book will show you how everyday numbers like these can also be used to make your research more powerful, and enable you to spot the abuses of number that are as common in research as they are in everyday life. This book illustrates how numbers can be used routinely and successfully for research purposes - without you ever having to consider confidence intervals, probability densities, Gaussian distributions, or indeed any of those complicated and generally useless things that appear in treatises on statistics. This no-nonsense guide should prove essential reading for all educational and social science researchers.
