Refreshed and updated PowerPoint resources aimed at assisting teachers with the delivery of the Eduqas A-level Business specification. These slides are designed to support the delivery of the Component Two topic of data analysis. They explain the use of data by a business and the different formats that data might be presented in with an examination of the benefits and drawbacks of pie charts, histograms, bar charts and infographics.  The presentation then considers the purpose and calculation of index numbers.  It examines the application of index numbers by business before concluding with a look at the benefits and drawbacks of their use.  The slides contain the Quick Fire Five questions and also a practice extended question (both with solutions).
