This workbook covers the stages involved in carrying out a statistical investigation in order to make an inference about a population. This includes posing a suitable comparative question, selecting random samples, using appropriate displays and measures, discussing sample distributions, creating informal confidence intervals and using them to make an inference. A report is produced, structured using the statistical enquiry cycle, in order to describe the investigation and communicate findings and conclusions.
The concise notes and write-on exercises keep student work together in a compact format, providing a useful end-of-topic revision tool.
This workbook is ideal for use in the classroom or for homework, home study and revision.
