The frequency is the number of times an event occurs; or the number of individuals (people, animals etc.) with some specific property.

A bar chart (bar graph) is a graph consisting of bars visually representing the frequency of objects or groups.

Interpreting scatter graphs

Problem solving with graphical representations of data

In this unit, pupils explore different graphs and charts as a way of presenting data visually. Pupils are introduced to scatter graphs and learn how to construct them in this unit. In the future unit, this understanding is extended to using a line of best fit to allow interpolation

In this unit, pupils interpreted and constructed pie charts based on their understanding of fractions and proportion

In this unit pupils will interpret and construct a range of representations of data including bar charts, pie charts and scatter graphs.

Graphical representations of data

A {{ }} file is used to support the creation of multiple charts with similar formatting and style.

Microsoft Excel and Google Sheets are two examples of {{ }} software.

Choose desired chart i.e. pie chart or bar chart

Put the steps for chart creation in order.

Yes - nearly all of the parts of the bar chart can be changed using the editor.

No - it is auto generated and therefore fixed.

The frequency scale is auto generated by the software. Can it be changed?

When data has been copied into the spreadsheet software, each piece of data needs to be in its own cell and the list needs to be {{ }}.

Where can you find the 'insert charts' button in Google Sheets or Microsoft Excel?

A {{ }} is a graph consisting of bars visually representing the frequency of objects or groups.

What is the frequency of 'planet' according to this bar chart?

Starting with the least amount of time spent reading put the months in order from least to greatest.

The {{ }} had the same amount of visitors on both Saturday and Sunday.

True - the categories are along the horizontal axis. e.g. food types

False - bar charts can be horizontal rather than vertical

Frequency is always found on the vertical axis of a bar chart. True or false?
