Statistics for the Teacher e-bog

Statistics for the Teacher, Second Edition serves as a guide to understand the significance and legitimate use of examination marks. This book examines the application of elementary statistics to examination marks involving only arithmetic. Organized into 10 chapters, this edition starts with an overview of the essential differences between counting and measuring in education. This text then explains the three factors that may be taken into consideration in interpreting the distribution of marks, including the nature of the examination, the type of group sitting the examination, and the marking scheme. Other chapters consider the most convenient measure of the standard of attainment or of the standard of marking, which is the average or arithmetic mean. This book discusses as well the method of obtaining a more accurate measure of the scatter. The final chapter deals with the method of determining the mean or average. Teachers will find this book useful.
