    Moving Averages Moving averages is a method used to smooth out the trend in data i. The idea is to filter out the micro deviations in a sample time range, to see the longer-term trend that might affect future results. The simplest form of a moving average is calculated by taking the arithmetic mean of a given set of values.

    To calculate the weekly moving average, we must first find the average of 7 days, starting from the first day. Next, calculate the average of 7 days from day 2nd to day 8th and use this data. For more information about finding the mean of a data set, please see How to calculate mean in Excel. There is an alternative way to add moving averages that also inserts the data into a chart. Start by creating a chart with the past data. You will see a plus icon to the right of the chart.

    You can add or remove elements from this menu. Click on the plus icon and move your mouse over the Trendline item. Click the right arrow and select the More Options… item from the dropdown menu. Select Moving Average and set the Period based on your data.

    You will see the same moving average line on your chart. Exponential Smoothing, like Moving Averages, is based on smoothing past data trends. However, this algorithm performs smoothing by detecting seasonality patterns and confidence intervals. This feature is available in Excel or later. You can use your own formulas, or have Excel automatically do this with its Forecast Sheet feature.

    Excel's Forecast Sheet feature automatically adds formulas and creates a chart in a new sheet. Follow the steps below to use this feature. Select the data that contains timeline series and values. Pick an end date for forecasting. These 3 new columns are for the forecast and boundary values for the confidence interval.

    The confidence interval is the range where future points are expected to fall. The range is calculated using normal distribution. If you click on the values in the new columns, you can see the formulas being used. Arguments of the formulas are populated based on the inputs in Options section. Customizing Advanced options can be found under the Options section in the Create Forecast Sheet dialog. Click the Options label to go to this menu.

    Forecast Start The timeline value where the forecast starts. If your timeline values are dates, you can select a date from the date picker.

    Excel can automatically detect where your data ends and pick the next timeline value. Alternatively, previous timeline points can be selected to see how the forecasting algorithm works. Confidence Interval Check or uncheck the input to show or hide the Confidence Interval calculations.

    Seasonality The length of the seasonal pattern. Excel can automatically detect this pattern. Alternatively, you can change the value to better fit your needs. Timeline Range Reference that contains the timeline values. This range needs to match the Values Range. Values Range Reference that contains the actual values.

    This range needs to match the Timeline Range. Fill Missing Points Using Excel can fill in the missing points based on the weighted average of neighboring points. This approach is called Interpolation. Alternatively, Zeroes can be selected to show the missing points as zeroes.

    Duplicate Aggregates Using An option for how Excel behaves when there are multiple values with the same timeline value. Calculating the average is the default option. STAT function. Linear Regression Forecasting in Excel can be done using various formulas. Although Excel still supports the FORECAST function, if you have or later, we recommend updating your formulas to prevent any issues in case of a function deprecation.

    Linear regression determines the linear relation between timeline series and values series. This linear approach makes it unsuitable for data with seasonality or other cycles, as well as non-linearity. On the other hand, linear regression is useful for causal models due to its simplicity. Add new timeline points to your data table for the values to use in the forecast. Select the cell where the first forecast value is to be calculated.

    Leave the reference as relative. A58 Select the range that contains the actual values. Make the range absolute.
