I’m constantly getting questions about my calculator. Unfortunately, I’ve been too busy to answer them all.

So here are some of the common questions:

Can I have a stand alone version or the source code?

No, I don’t have time to program a stand alone version and since it brings a decent amount of traffic to this website, I don’t want to just give it away.

However it is just a math equation, that you can learn freely on the ‘net. It may take you awhile to figure out if you’re not a math geek though.

Why doesn’t the Calculator show a exact percentage instead of above 80, 90, 95, etc?

That’s because I couldn’t find a math equation for getting the exact probability, instead I found a table of results and their probabilities and used it to program it the way it is.

Is this the best way to tell if my results are statistically accurate?

As far as I know, yes. There are many other equations for this type of thing, including one called a “Confidence Interval” which gives somewhat different results.

My calculator uses the Chi Squared equation with a Yates Correction. Which is often used to determine whether survey results are valid.

If someone knows of a truly better equation, let me know and I will make a calculator for it. For now it seems like this is the most dependable equation.

In other news…

This website was attacking by some spam robots that spammed all kinds of weird stuff in the comments. Evidently someone specifically designed software to spam this blog.

Unfortunately I had to disable comments to stop the spam. When I get time I will rewrite the php and add some type of validation that will block the spam.

Also I’ve spent the past few months working on my biggest project yet, and so far the results are amazing.

It’s not an IM product, but if I decide to sell it (via a membership site), I will post a link to it here so you can benefit from it.

That’s it for now…
