You can also use the function GROWTH to predict the exponential dependence in Excel.įor linear dependence, use the TREND function. Therefore, there are more errors and inaccuracies when building a linear trend. You need to set the number of periods in the parameters to see the forecast on the chart.Īfter all, there is the exponential dependence in our example.

Most authors recommend using a linear trend line for forecasting sales. Free downloadable statistics software (Excel add-in) plus comprehensive statistics tutorial for carrying out a wide range of statistical analyses in Excel. The trend equation is a model of the formula for calculating the forecast values. R2 = 0.9567 which means that this ratio explains 95.67% of changes in sales in process of time. The course covers important statistical terms and definitions, and then dives into techniques using the tools in Excel: formulas and functions for calculating averages and standard deviations, charts and graphs for summarizing data, and the Analysis ToolPak add-in for even greater insights into data. We choose a polynomial trend that minimizes the error of the forecast model. We will add a trend line (the right button on the chart - «Add Trend line») on the chart which shows the actual product sales volume.Ĭonfigure the parameters of the trend line: We will compose the forecast of sales using the data from the previous example. Once enabled the Data Analysis ToolPak will be located in the the Data tab all the way to the right.
The Add-Ins window will open, add a checkmark to the check box next to Analysis ToolPak, click OK. For example, = SQRT(SUMXMY2:(C3:C5 D3:D5)/3). At the bottom of the window select Excel Add-ins from the drop-down to the right of Manage:, click Go to proceed. Results of the analysis:Įxcel uses next formula to calculate the standard errors: = SQRT(SUMXMY2('Actual value range' 'range of forecast values') / 'size of the smoothing window'). We tick the «Chart Output», «Standard Errors».Ĭlose the dialog box by clicking OK. The program will place the smoothed levels here and the will define size independently. Output interval –is a reference to the upper left cell of the output range. You will see all the available Analysis Tool Pack. Step 5: Once you click on Go, you will see a new dialogue box. Step 4: Once you click on Add-Ins, at the bottom, you will see Manage drop-down list. The damping factor is the coefficient of exponential smoothing (default is 0.3). Step 3: After selecting Options, select Add-Ins. The input interval is the range of sales values. This alignment method is suitable for our dynamic series, the values of which fluctuate strongly. Select «Exponential Smoothing» from the proposed list of tools for statistical analysis. The connection of the « Data Analysis » add-in is described here in detail.
Click at the bottom «Go» to «Add-Ins Excel» and select « Data Analysis ». On the «DATA» tab click the «Data Analysis» button. The task is to identify the main development trend.Įnter the sales data in the Excel spreadsheet: Example: a sales network analyzes data on sales of goods by stores located in cities with a population of fewer than 50,000 people.

As a rule, regular changes in the members of the series are predictable. Their variability is divided into regular and random components. The tab will be called Data Analysis, and you can click on it to start performing statistical analysis in Excel.If you capture the values of some process at certain intervals, you get the elements of the time series.
Now a new button will appear under you Data menu. Navigate to the tab Add-ins and click on Go, as you see in the image.Īctivate the Analysis ToolPak, then click OK. You can work with ANOVA, histograms, t-tests, correlations, descriptive statistics, regression and much more. Now, all you need to do is analyze them using your knowledge of statistics. Everything is done automatically: you enter data, choose a required statistical tool and results are presented to you. The best thing about using Excel for this purpose is that you don’t have to use complicated formulas (though you certainly can, if you want to).

Maybe not in full detail like SPSS or R, but for the most basic statistical analysis it will be adequate. However, Excel can perform some simple statistical analysis as well.
