Introduction

The following techniques should be introduced as soon as possible and used throughout the course:
• using statistical terms correctly eg qualitative and quantitative data, primary and secondary data, independent and dependent variables, discrete and continuous variables, population, representative and random samples, outliers.
• using spreadsheets to carry out calculations and display results in tables and statistical charts and graphs
• checking calculations using estimates, inverse operations and different methods.
Although the topics are listed separately below, it would be more beneficial to follow a number of statistical investigations through from the initial collection and organisation of data to an analysis of the situation making use of statistical charts and measures. Where possible these investigations should reflect the students’ other areas of work and interests.
Note that topics given below as Extension Opportunities are optional, but students must do some work outside the main core in their coursework portfolio.
