Real Statistics Resource Pack

The Real Statistics Resource Pack contains a variety of supplemental functions and data analysis tools not provided by Excel. These complement the standard Excel capabilities and make it easier for you to perform the statistical analyses described in the rest of this website. 

We now explain how to download and install the Real Statistics Resource Pack for use with Excel 2010, 2013, 2016, 2019, 2021 or 365 on Windows. If you are using Excel 2007 click here. If you are using Excel 2003 or a prior version of Excel click here. Finally, if you are using Excel for the Macintosh click here.

Keep in mind that there are also two versions of Excel, at least for Excel 2010, 2013, 2016, 2019, 2021 and 365, the 32-bit version and the 64-bit version. Most people use the 32-bit version. The Real Statistics Resource Pack works in both versions of Excel.

Download

Real Statistics Resource Pack for Excel 2010, 2013, 2016, 2019, 2021 or 365 for Windows

Two versions of the software are available. The first provides help support (via Insert Function fx) for Real Statistics worksheet functions but can slow down certain Excel operations. The second version omits this support but does not degrade Excel operations.

Both versions of the software are compatible with all Windows releases of Excel from 2010 until the present. After downloading the software make sure that you install the software as described below.

Downloading either resource pack means that you accept the License Agreement.

Solver Installation

Before trying to install the Real Statistics Resource Pack make sure that Excel’s Solver is installed on your computer. You can check this as follows:

  1. Open up a blank Excel spreadsheet
  2. Press Alt-TI (i.e. hold down the Alt key and press the T and I keys).
  3. On the dialog box that appears make sure that the Solver add-in is checked. If not, check it and click on the OK button.
  4. If the Solver add-in was not checked you need to close the Excel file before proceeding to the Real Statistics installation.

You can also accomplish step #2 by selecting Developer > Add-ins|Excel Add-ins.

Real Statistics Installation

Once you have downloaded the Resource Pack and made sure that Solver is installed, you need to install the Real Statistics Real Pack using the following steps:

  1. Move the Resource Pack to where you want it located on your computer (see our recommendation below). Caution: Once you install the resource pack at a particular location it will be more difficult to move it later.
  2. Open Excel, but don’t try to open the XRealStats.xlam or XRealStatsX.xlam file that you downloaded earlier.
  3. Select File > Help|Options > Add-Ins and click on the Go button at the bottom of the window (see Figure 1). Alternatively, you can simply press Alt-TI (i.e. hold the Alt key down and simultaneously press T followed by I) and the dialog box shown in Figure 2 will appear.

    Add-in dialog box
    Figure 1 – Add-Ins dialog box 1
  4. Check the Xrealstats or Xrealstatsx option on the dialog box that appears (see Figure 2) and click the OK button. NOTE: If you have previously activated a different version of the Real Statistics software you must uncheck the option corresponding to that version.
  5. If this option doesn’t appear, click on Browse to locate and then choose the xrealstats.xlam or xrealstatsx.xlam file. Then complete step 4 as described above.
Add-Ins dialog box

Where to place the Real Statistics Resource Pack

While you can place the Real Statistics Resource Pack anywhere on your computer, we recommend that you put the file in the following folder:

C:\Users\user-name\AppData\Roaming\Microsoft\AddIns

where user-name is your username in Microsoft Windows. Since some of these folders are hidden, you may find it convenient to enable showing hidden folders. For example, in Windows 10 or 11 you can do this by opening Settings and then typing Show Hidden Files and Folders in the search field. Next, check on the Show hidden files, folders, and drives option in the dialog box that appears, and then click on the OK button.

Installation of Upgrades

Once you have installed the Real Statistics Resource Pack as described above, to install a new version of the software you don’t need to repeat these steps. You only need to delete the previous version of the resource pack and put the new version of the software in the same location as the previous version.

Troubleshooting

If there is a problem during the installation try one or more of the following:

  1. If Excel is running, close it. Find the file with the Real Statistics add-in. Right-click on the file and click on the Properties option from the menu that appears. Towards the bottom of the General tab of the Properties window, you will see the security message “This file came from another computer and might be blocked to help protect this computer”. Next to this message is the Unblock checkbox. Make sure this is checked and press the OK button. Start Excel.
  2. Click on Options from the File ribbon and then choose the Trust Center option on the left side. Next, click on Trust Center Settings …. Now, click on the Macro Settings option on the left side and make sure that it is Disable all Macros with Notification. Also, click on the Trusted Locations option on the left side and click on the Add New Location… button to add the folder that contains the XRealStats or XRealStatsX file as a trusted location.
  3. Try opening a blank Excel worksheet and press Alt-TI. Uncheck the Xrealstats add-in and close Excel. Now open a blank Excel worksheet and press Alt-TI. This time check the Xrealstats add-in

Most importantly, remember that Solver must be installed. To check this, press Alt-TI and make sure that Solver (as well as Xrealstats or Xrealstatsx) is on the list of add-ins with a checkmark next to it.

Real Statistics Functions

Once you have installed the Real Statistics Resource Pack you can use the Real Statistics functions in the same way as you use the built-in worksheet functions supplied with Excel. These functions are described throughout the rest of this website. A complete list of these functions can be found on the Tools menu of the website (or at Real Statistics Software Capabilities).

Real Statistics Data Analysis Tools

You can access the Real Statistics data analysis tools in one of the following ways, as described in Accessing Real Statistics Data Analysis Tools:

  • By pressing Ctrl-m or
  • Clicking on an icon on the Add-Ins ribbon or
  • Clicking on an icon on the Quick Access Toolbar or
  • Via the Macro dialog box

A dialog box will now appear that lists all the available Real Statistics data analysis tools.  You need to choose one of the data analysis tools from this list.

A dialog box will then appear as described in Real Statistics Data Analysis Tools which enables you to specify your input data and choose from available options. You can also access Help to get more information about the selected data analysis tool.

A complete list of Real Statistics data analysis tools can be found in Real Statistics Data Analysis Tools.

Uninstalling the Real Statistics Resource Pack

  1. Open Excel
  2. Press Alt-TI
  3. Uncheck the Xrealstats or Xrealstatsx option on the dialog box that appears and click the OK button.
  4. Close Excel and delete the file that contains the Real Statistics Resource Pack.

  1. Hi I’m trying to do a multiple regression analysis on a dataset that has a independent variable with a maximum value (it’s a 0-100 range). I’m a student and just starting so wondering if theres anything simple I can do to account for this, or if I’m better off just capping my projected values. It’s not for anything major just a marketing game.

  2. Hi Charles,

    I just wanted to say how fantastic this statistics add-in is. I needed something (free) that my students could use for a practical statistics course. Your RealStats worked a treat and meant that they could do proper analyses with a relatively small learning curve.

    I would recommend it to all who need to do data analysis and don’t want to invest in commercial products.

    Many thanks.

  8. Hi Charles,

    This is an awesome pack you have here and sharing this resource for free. I really appreciate it. Keep up the good work. I use the time series package.

    Any idea why ARIMAX does not seem to work. Is there anything I’m missing out.

    ARIMA and SARIMA work perfectly fine and I particularly like the added ‘Solver’ functionality to optimize the parameters.

    Reply

    • Hi Ken,
      Can you specify what doesn’t work with the ARIMAX data analysis tool?
      If you email me an Excel file with your data I will try to figure out why it doesn’t work.
      Charles

      Reply

      • The forecast that is generated look more like differences between two consecutive time periods. The time series data I have are all positive numbers, however, I got a mix of negative and positive numbers as forecast from ARIMAX which is not supposed to be. I wish I could share the data, sadly I am not able to share the data.

        In addition, I tried to record macro in excel 2016 to automate certain forecast daily but I couldn’t get excel to do it. Is there a way round this. I appreciate your feedback.

        Reply

          • ARIMAX is giving me negative forecasts for a non-negative time series data. I tried it on another data, I got the same thing: negative forecasts. The forecasts I get from both trials do not appear to match the level of the time series data. For example, my daily data ranges from $26M to $38M but ARIMAX gave forecasts of $1M, $3M, -$2M (negative number), $500k, etc. on all days. I did not get a single daily forecast of up $26M. These forecasts do not reflect my data.

          • Hello Ken,
            It does look like something is going wrong, but I need to see some data before I am able to identify where the problem is. If you can send me an Excel file with data that displays this problem, I will try to figure out what is going wrong. You don’t need to send me the real data, just some data that produce these sort of results.

    I have downloaded the Real Statistics Resource Pack, and installed it following your recommendations (I saved the file in the C:\Users\user-name\AppData\Roaming\Microsoft\AddIns folder). However, every time I restart Excel, the pack is not loaded any more and nothing happens if I click CTRL+M. I always have to press ALT+TI, locate the pack again in Browse, and click “OK” when Excel asks me if I want to re-load the pack). Any suggestion on how I can prevent this from happening?

  15. Hello Charles, I am writing to thank you. I have recently returned to graduate school and am recovering from statistical traumas of undergrad many years ago. I appreciate your website and the open source work you have done to utilize the computational power of Excel rather than needing a specific stats program. Your example tables were particularly helpful to understand how to set-up the Spearman’s Rank Correlation I needed to run. Keep up the great work!

  17. It is an issue of trust. You need to install in C:\Program Files\Microsoft Office\root\Office16\Library or another trusted location. If the add-in is not trusted ether by location or signature it will not load and =Ver() will not work because the add-in did not load. It doesn’t matter what Options >> Add-ins states.

    I recently uploaded it and started using it and I am still learning about it. What it is happening is after I create any workbook and use the applications, it runs and gives me the results, however anytime I save them and I re open them or a new workbook, the Add-ins “disappears” from the ribbon and I must start from file>options> etc …
    Could you please give me a hand with this? or is it what is suppose to happen,

    Please help me with a problem I cannot solve:
    I installed the Resource Pack ver. 7.0.6 under Excel 2010.
    I try to use the module “Statistical Power and Sample Size” – Cronbach’s alpha.
    When I input “Cron Alpha 0” = 0,7 and e.g. “Cron Alpha 1” = 0,9, I get the error message “Cron Alpha 1 must be a number between -1 and 1 not equal to Cron Alpha 0”.
    A similar error message also appears in other modules, e.g. ICC.
    Also, I have to manually change alpha’s default decimal dot to a coma elsewhere in the Resource Pack, otherwise I get the message “Alpha must be a number between 0 and .5”.

  27. Hi Charles
    I apologize if someone has already addressed this topic.
    I just wanted to comment that the ‘Alt-TI’ key combination does not work, at least in Office 2010. To get to the Excel Add-Ins window the full sequence is:
    File menu > Options > Add-Ins > Excel Add-Ins > Go… (as you explain later at some point during the Installation instructions). There must be a different key combination than Alt-TI.
    Best,

    • Thanks Carlo. Alt-TI does work for the English-language version of Excel 2010. This is probably not the case if you are using the Italian version of Excel.

  35. Hi Charles,

    I followed the installation guide for realstats and i can see it in the active application add ins list however i cannot seem to get it to work. When i type in =VER() i get #NAME? in the cell. I also can’t seem to access the add in through any of the methods (ctrl-m, add ins ribbon, QAT, or macros). I put it in the recommended folder on my PC and made that location trusted to excel as well but still no luck..
    I’ve also uninstalled and reinstalled the entire thing twice with no luck.. do you have any idea why it might not be working?

    Reply

    • The fact that you get #NAME? when you enter =VER() means that the software hasn’t been installed.
      When you press the key sequence AL-TI do you see Solver and XRealStats on the list of add-ins with checkmarks next to them? If not you need to click on the Browse button to locate the file containing the Real Statistics software (as described in the Installation instructions).

    I’ve a problem using the plugin. I installed the plugin following the instructions. Immediately after activating the xrealstats add-on, the “Additional Components” tab becomes visible in the ribbon bar of Excel and within it I can select Real Statistic and use the plugin functions. However, the next time I restart Excel, the “Additional Components” tab disappears and I cannot longer use the plugin. Afterwards by deactivating the plugin and reactivating it, the tab becomes visible again, but the next time Excel is restarted the tab disappears again. I tried to install the plugin on 2 different pc with 2 different office version (2016, 2019) but the problem is the same. Could you help me? Many thanks.

    But I had a heck of a time finding these installation instructions. I suggest adding this page’s link to the “Free Download” page and to your home page (and wherever the download link appears).

    But wow, good. I wrestled with SPSS for a year. It’s very sophisticated and elegant but a lot of tech overhead, especially for people who don’t do hard-core stats.

    So this add-in is looking good.
