Analyzing your data without breaking the flow of your presentation is engaging and takes seconds to set up. The ‘before and after’ question is the most commonly used - it allows you to ask the same poll at two points in a presentation, then compare the results on one slide in order to show knowledge retention or shifting opinions. Other options include recalling past polls, totaling a series of polls and of course displaying a leaderboard for a quiz.
In other words, analysis slides take information from questions that have already been polled and re-publish them in different ways.
Watch this short video as an introduction to analysis slides:
There are four types of analysis slides:
- Comparison analysis
- Recall analysis
- Total analysis
- Leaderboard
The analysis slides will not display the results to participant devices. The results will only be displayed within the PowerPoint presentation.
1. Comparison analysis
Use this analysis option if you want to check if your participants opinions have changed or whether learning has taken place during your presentation. With the Comparison analysis slide, one can compare the results of multiple questions on a single slide.
A common use for this type of analysis slide is also called a 'Before and After' comparison. If you want to ask a question at the start of the presentation and then ask it again later in the presentation, this option allows you to display & compare the results of both polls on the same slide.
Follow these steps to create a comparison analysis slide:
Create an initial poll slide and duplicate this slide to run later again in your presentation for the comparison. (Use 'Control +D' on your computer as a shortcut to create a duplicate slide.) Both slides will show sample results.
Select the Add Analysis Slide option from the PowerPoint ribbon.
From the pop-up box select the 'Compare' analysis type. You can compare the results of up to 6 polls on one slide. (In most instances, you will only compare two polls with each other.)
In the case of a 'Before and After' scenario the Master Poll would be the initial poll you created in the presentation. Use the drop-down arrow to select the relevant question slide.
The 'Compare with' section is where you select the second poll you wish to compare (in other words the duplicate question that is later in your presentation). Use the drop-down arrow to select the relevant question. One can alter the result labels to indicate when the question was asked. The default setting is 1st Vote on the first slide. When comparing the second poll, the label setting will default to 2nd Vote.
Optional: Change the 'Slide Title' (this will be at the top of the comparison slide with both results - slide 3). Once you have added the polls you wish to compare and altered any labels press the Add button.
A new comparison analysis slide will automatically be added to the presentation and will show the layout to give an example of how the results will be displayed. (Remember to ignore the percentages at the end, it is only for display purposes).

When you reach the comparison slide in your presentation, the comparison slide will pull data from both the polls you selected. You will be able to see clearly see the results side by side for direct comparison.

2. Recall analysis
The Recall analysis slide can be used to recall the results of a previous polled question. In some situations require you to call back to a previous poll to reiterate a point or remind participants of their responses. Another common use of this feature is if you have decided to hide the results of a poll with the intention of revealing them to the audience later.
To set up a recall analysis slide follow these steps:
Select the 'Add Analysis Slide' option from the main menu in the PowerPoint ribbon.
When the pop-up box appears, select the 'Recall' analysis type.
Under 'Master Poll' select the poll you would like to recall the results from. You can also change the 'Slide title' if you want. Then press the 'Add' button.
A duplicate slide of the question will appear in your presentation. Remember to move it to a later section in your presentation.
When you ask this question in the presentation the first time, the participants answer the question normally. The second time the question appears in the presentation, the results will automatically be revealed from the first time it was asked. (In other words it brings up the same voting slide results later in the presentation.)
3. Total analysis
The Total analysis slide can be used to add together the votes of multiple polls into one and is used when you want to see combined results together.
A common use for this type of analysis slide is if you are asking the same question to different audiences, multiple times and want to sum together all the instances you have polled the question.
Total analysis slides are set up the same way as comparison polls using a 'Master poll' and the polls you want to combine it with.
When using the Total analysis slide, both polls must use the same number of choices or voting range.
To set up a total analysis slide follow these steps:
Select the 'Add Analysis Slide' option from the main menu in the PowerPoint ribbon.
From the pop-up box select the 'Total' analysis type.
Select the first instance of the poll as the 'Master Question'. Use the drop-down arrow to select the right question.
The 'Combine With' section is where you select the subsequent polls you wish to add together. You can total the results of up to 6 polls on one slide.
Change the 'Slide Title' (this will be at the top of the comparison slide with both results - slide 3).
Once you have added the polls you wish to total together, press the 'Add' button.
It is possible to copy a slide containing results from another presentation (if it is the same question) and inserting it into your current slide deck to enable analysis slides. (The slide containing the questions together will the results will be copied.) This creates a workaround if you have asked the question before and don't want to bore the participants by asking it too many times.
4. Leaderboard
