Session 4: Handling data

Introduction

Data is a big part of our lives and can be represented in many different ways. This session will take you through a number of these representations and show you how to interpret data to find specific information. Before delving into the world of charts, graphs and averages though, it is important to make the distinction between the two different types of data:

  • Qualitative data – this is data that is not numerical e.g. eye – colours, favourite sports, models of cars.

  • Quantitative data – this is numerical data related to things that can be counted or measured e.g. temperatures, house prices, GCSE grades. Quantitative data can be discrete or continuous.

By the end of this session you will be able to:

  • identify different types of data
  • create and use tally charts, frequency tables and data collection sheets to record information
  • draw and interpret bar charts, pie charts and line graphs
  • understand there are different types of averages and be able to calculate each type
  • understand that probability is about how likely an event is to happen and the different ways that it can be expressed.
