Better handling of numeric answers
when numerical answers are required, display a histogram of the distribution of responses, so lecturer can see roughly how many get close to the right answer, and how many are far off.
Thanks for your feedback! We always welcome new activity type ideas, and a way to visualize numeric responses sounds really interesting. We’ll consider this in our product roadmap planning.
I agree that this is an essential tool. Some display options I would like to see for numeric responses include:
(1) ordering numeric responses from smallest value to largest value
(2) similary, displaying a frequency table of numeric responses, from smallest value to largest value,
(3) obtaining summary statistics from numeric responses, including n, min, max, mean, mean, median, and sd
(4) presenting a standard visualization of numeric responses like a histogram
Is this feature only available in the premium plan?
I will add to other comments that the lack of a numerical response option is a severe limitation for Poll Everywhere in the sciences. Many other systems (ranging from Moodle to iClicker) have this feature, and it's absence makes it hard to fully implement Poll Everywhere in my classrooms
Numeric submissions are displayed with individual submissions streaming but the focus being a sum of the submissions. (so people can respond with a commitment to give a certain number of dollars or hours to an initiative, and it sums up the total, especially if you could display against a target number) (people guessing the number of something and an average/median is displayed along with a stream of indiv. submissions; or their submitting their ages, or their household incomes, or something like that. This empowers pollsters to gather information about the body of pollees and instantly echoing it to them in aggregate terms). There are many, many more applications of this summing/averaging capability. I WANT IT!

The possibility of graded questions with numerical answers and/or phrase answers would be great.

Immediately calculate sums or averages of numerical, open-ended questions
This is not only an obvious feature, it's one that's included in many of your competitor's programs. (See, e.g., TurningPoint and iClicker). This is also very easy to implement: all you need to do is validate the input as numeric, bin the data, and then pass it to whatever code you're already using to plot your barcharts. It would seriously take like three lines of Python.
Hi Christina - unfortunately we do not have a way to accept a range of numerical answers right now. We could only accept free text and allow your participants to submit any number of letters OR our Multiple Choice Polls.
It is something we hope to get to in the future, but is still more in the "future dream" phase.
We have an interest in allowing students to submit a numerical answer, allowing for a set range or tolerance. Does this exist?
This seems like an obvious feature to include. How hard can this be? I don't see it implemented and I could really use it!

While Brainstorming open ended textual ideas or voting for predefined options is very powerful, the business world also is about numbers and estimations. Imagine that you start to ask your sales people about sales revenue in the next period and have them estimate without influencing each other? You may start to eventually use the wisdom of the crowd for your business planing and modelling...
I would love to see this feature as well. This would be very useful in science & engineering classrooms where students are working on order-of-magnitude reasoning or estimation problems, and you want to get a sense of the distribution of responses from the class as a whole. Extreme outliers could be excluded by autoscaling the histogram.
I am also very interested in this function! It would be very useful to be able to calculate the mean of simple scorings. Example: Please rate your level of satisfaction with my presentation on a level 1=not satisfied at all to 5=extremely satisfied. Are there any ways to implement that?

"What would you guess is the average height of people in the room?"
The respondents should enter any numerical value. Might PollEv summarize the result with a frequency chart with mean, median, standard deviation?
I'm a professor in mechanical engineering. Poll everywhere is exactly what I need for pop quizzes, except it lacks one essential and perhaps easy-to-add feature: I need automatic grading of questions with a numeric answer (or answerS, with commas separating the values). tophatmonocle (a competitor of yours) provides this feature, but is somewhat cumbersome for other reasons - your system looks easier to implement, but doesn't grade questions with numeric answers, and at the college level, multiple guess testing is rather, well, silly. Can you possibly incorporate this feature? please? :)

I am not sure if that is already possible since I cant seem to figure out how to use it BUT it would be nice to have a percentage-type question format. For example: "What is the divorce rate in the United States"? or How many people are there in Congress? People put a number in there and then Poll Everywhere presents a diagram with an average (and maybe a standard deviation" .... This would be a great addition for classroom instructors I think ...
