The Poll Cruncher

The app below shows how polls are actually probability distributions, which helps when it comes to getting your head around issues like margins of error and whether any statistically significant change has occurred over two consecutive polls. Just follow the instructions, it’s all pretty self-explanatory.

Just note, with the minimum and maximum values that you can put in, make sure the minimum is actually smaller than the maximum, even if it means using negative signs on your input.
