A new series of resources aimed at assisting teachers with the delivery of the Edexcel A Level Business specification. This resource specifically looks at topic 3.3.1. Quantitative Sales Forecasting. This PowerPoint presentation looks at the calculation of time series analysis including both three period and four-quarter moving averages. It then proceeds to examine the role of scatter graphs, lines of best fit, extrapolation and variation analysis upon sales forecasts before concluding with an assessment of the techniques limitations. The slides contain several activities with suggested answers including the Quick Fire Five and a 10 mark practice question. The clear and well-presented nature of the slides are aimed at helping students to understand the topics with each topic analysed to provide a balanced assessment of the theory.
