Session 3: Handling data

Introduction

Maths is relevant to so many aspects of our everyday lives and you should now be feeling confident with using numbers, measuring and calculating with money and units of time.

This session focuses on data. We all use and generate data on a daily basis – companies use it to track our shopping and lifestyle habits and offer us personalised deals and you may well collect data as part of your job to find out which item is selling best, how many clients/patients are satisfied with the services provided or to identify areas that need improvement.

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.

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

  • identify the two different types of data and where they are used

  • 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.

Before delving into the world of charts, graphs and averages it is important to make the distinction between the two different types of data – discrete and continuous.

We all use and generate data on a daily basis. For example, companies use data to track our shopping and offer us deals. Data has become very important.

There are many different types of data. Continuous data is something you measure, like, the length of a piece of wood. A box of nails is usually something you can count, which is called discrete data.

Different ways of displaying data include using graphs. A line graph can show the relationship between some data about a shelf. A pie chart can show the ways that someone spends their time, which is easy to see and understand as a picture.

Gathering data can help to work out different types of average-- like the range, which is the difference between the lowest and highest values. Or the median, which is basically, the middle.

Data can even be used to work out probability – how likely are unlikely something is to happen, which can help you avoid unpleasant surprises.
