Sample graph from the program.

NOTE: This data is not real, i don't have automated roller working yet.  I hope to have automated rolling working in next 10 days.



The red lines you see show where the data for a fair die should lie with 95% confidence.

If these were real results, this die could be confidently labeled as NOT fair.

A real report from real rolls:

This die looks like 5s come up more than they should (and 1s less)..

tomos:
Image looks great :)

In the image, what exactly does 'red is 0.95 confidence int. for fair die' mean?
Does it mean that within the range of the red lines in the bar-chart means you have 95% 'confidence' in the results?

Damn, I see you already answered that in your previous post. So, this die is not fair, due to the results for 5 being too high (took me a while to figure that out :-[ )

What is means is that if you repeated this experiment over and over with a perfectly fair die, rolling this many times, you would expect the counts to fall within those red bars, 95 times you ran the experiment out of 100.

thanks, I had missed your previous post (edited post to reflect that).
This is very impressive :up:
