You can use several different sets of values in one or multiple formulas to explore all the different results. What-If Analysis is the process of changing the values to try out different values (scenarios) for formulas. To get the total items bought by each buyer, drag the following fields to the following areas. Then, it will create a pivot table worksheet. It will also create a new worksheet for your pivot table.

On the Insert tab, in the Tables group, click PivotTable.Ī dialog box will appear.

To insert a pivot table in your sheet, follow the steps mentioned below: This data is perfect to understand the pivot table. The sample data that we are going to use contains 41 records with 5 fields of information on the buyer information. It helps take an extremely large data set and see the relevant data you need in a crisp, easy, and manageable way. They organize and rearrange statistics (or "pivot") to bring crucial and valuable facts to attention. We use them in summarizing the data stored in a table. Pivot tables are known for being the most purposeful and powerful feature in Excel. Let’s use the SUMIF function to calculate the cells based on numbers that meet the criteria. The Excel SUMIF function returns the sum of cells that meet a single condition. Let’s get the count of items that are over 100. You can now filter according to your needs.ĬOUNTIF is a very commonly used Excel function used for counting cells in a range that satisfy a single condition.

You will notice the arrowheads have appeared in the columns.

Go to Data Tab > Sort and Filter > Filter.

Click on any single-cell inside your data.

We use filtering when we want to get the data that will match the specific conditions.

Add the levels by which you want to sort.

Click on Sort which can be found on the Sort & Filter group, on the Data tab.

You can also sort on multiple columns in your worksheet. Note: To sort in descending order, click ZA.

Next, to sort in ascending order, click on AZ which is found on the Data tab, in the Sort & Filter group.

The first step is to click on any cell in the column which you want to sort.

You cannot use any one method when making forecasts: the probability of large deviations and inaccuracies is large.Let’s sort the data on the basis of Units. 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. 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. 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. 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. The damping factor is the coefficient of exponential smoothing (default is 0.3). 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. If you capture the values of some process at certain intervals, you get the elements of the time series.
