How to use:

Enter either observed frequencies or percentages for each category in a distribution;
If entering percentages either round up values to a full number or enter decimals as full numbers (e.g. 78.1 %=781, 10.0 % =100);
Enter '0' if a category has no observed frequency;
Confidence intervals should only be trusted when there are more than 3 categories;
Numbers can be entered manually or using copy & paste.
