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.

Now, 8 years later, I still think this would be an invaluable tool for any STEM teacher. It is currently the main reason I do not use PollEv for immediate feedback assessment tools.
It would be very useful!
The teacher can ask students to work a problem and the students type in a number. Then a histogram appears of the responses and changes in real time as more students answer.
I am still desperately looking for a tool which can do this. I want students to guess/estimate numbers (e.g. how many people are currently alive, what is a countrie's GDP, what is the distance between the moon and planet earth), or submit certain information about themselves (e.g. age or height). The results are only interesting as a distribution/histogram. I don't want to do MC, because that is narrowing it too much done, and open ended doesn't summarize well for these numerical inputs.

This would be so useful for all STEM classes. I'm shocked it isn't available.

Open-ended polls are great, until a student realizes that they can post a funny joke and everyone in the class will see it. One way to avoid this is to require students to sign in, but I'd rather not do that. Instead, I'd like to have polls in which students can only type in a number.
Just tried looking for this today. A histogram would be great. But even just the avg numeric response would be great. Can we, at least, be able to restrict answers to numbers rather than text?

Just thought I'd pop in and add another vote for this idea, 6 years later (😱😱). For those of us who teach anything STEM-based, this is an important feature.
At the very least, I would like a way to force numerical responses to free text questions. i.e. any non numerical response will give the respondent an error message and a chance to redo it.
I have figured out how to download the responses into a Google Sheet so I can make my own bar charts etc since PollEverywhere doesn't want to implement them. But it would work better if PollEverywhere forced the format of the responses to be correct.
I think this is slightly different from an earlier post about numerical answers, where as I understand, one answer is the 'correct' answer.
I would like students to enter a numerical response to a question, e.g. 'What is your age?'. I would then like to be able to display the mean/median of the responses, and perhaps a histogram or even scattergram (if another numerical- or categorical-response question appears in the same survey to allow for comparison).
My understanding is that this feature is still not available (i.e. a year after the original, similar discussion)?
It would be great if this could be explored - seems really odd that it's not available (I've seen it in other software e.g. bristol surveys)
This is different from multiple choice questions. The student types a numerical answer in response to a question. The instructor has the ability to accept the correct numerical answer with an assigned degree of uncertainty. e.g 2%.

Add formulas within polls that would allow for averaging across a poll’s answer choices. For example, some of our polls ask participants to select between five ratings from 1 – 5. We’d like to be able to average participants' ratings in real-time.
This is similar to "Allow for numerical answers in open ended questions" but the graph might be slightly different. I want to be able to collect numerical data from a group and display a graph in Powerpoint. Today, I have to have a range in mind and give them options (e.g., A = <10, B = 10-19, C=20-21, etc.). But PollEverywhere should just be able to accept all of the numerical responses and create a graph, adjusting the range as needed in a histogram. I can also see uses for an xy (scatter) plot, but I'm not sure how you can get there in a poll, unless they enter two numbers (e.g., "10,12" or temperature, relative humidity).
I'm amazed that, five years later, this feature is still lacking.

This really shouldn't be hard (most horrifying thing software company ever wants to hear!) as its been available since at least 2002 in other products. Personally, I'd like to see it just pop up a histogram. That's what I did back in 2002 when trialling clicker software for Ohio State. I'm sitting here actually quite stunned that this isn't available.
Basically, allow only numerical input on www (and discard SMS non numerical input) and throw up a histo, maybe w/ sample size, mean & median printed at bottom.

Numerical answers with a live histogram plot on the display. This feature was available in an old clicker tech that I used in 2002!
I'm a professional speaker about ag, econ, and finance, and being able to poll my audience about their cost of production (farmers) or revenue growth rate (small businesses) and plot the result would be so handy I'm sort of shocked you don't have it already. I used this back when I taught basic econ, too, when I polled students on their hourly wage if they had a job--and categories will completely miss the points that are going to be the most fun to discuss!
I'd be happy to follow up on this with you...email@example.com
I would vote for this as well! This is exactly what I need for the polls we are running.
EDUC 200A commented
Make the period in a decimal stay with the number... eg 1.26 should appear in a word cloud exactly like that. now it appears as two separate number 1 and 26!
Give additional character allocation to both the question and the responses.
Fix the connection to PP slides
Allow one to go back and forth among slides and not lose the questions

I would like to be able to have students type in numerical answers and for the software to generate a bar graph or table showing the each unique numerical answer and the number of times it was entered.
Nick Hambridge commented
Create an option so that 'average score' displays in real-time on the poll. For example, I ask participants to score risks from 1 to 5, 1 being low risk and 5 being high risk. I need the poll to show me in real time the average score.
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
