The idea of "effect size" is very relevant in statistics. If often happens that
a test statistics is significant, but the association has no practical meaning.
This is because a extremely large sample size alone can find significant n
extremely small effect. Cramer's V is a statistic that assess the effect size or
practical significance of the association between nominal variables. Check it

Great changes to improve user experience are coming very soon. I have written
recently many math and stats solvers that I'll be adding to the site. I've been
polishing the scripts we already have and this is almost turning into a full
time job. As many users are aware, we have had ads for the last few months, and
even though I don't like ads, it is the only way to support the site, which is
turning into a full time job by now. I'm looking for a more efficient way of
using ads so that the site can be ad-supported and it continue being free that
way.
Various Statistical Tests
November 2nd, 2014
More Stats tests done. I have finished a t-test for one population mean with
unknown population standard deviation and a Chi-Square test for one population
variance. Pretty much as the other solvers I have added, they are simple to use:
define hypotheses, and parameters of the test, and a detailed step-by-step
calculation is performed.
Z-tests
October 31st, 2014
I've been working on these for a while and I finally finished them. I added a
z-test for one population mean and a z-test for one population proportion. Very
user friendly, define hypotheses, and parameters of the test, and a detailed
step-by-step calculation is performed. Recommended.

associated with each of the categories, and a bar chart rendered by the script.
Mortgage Calculator
October 8th, 2014
Not exactly the typical calculator we do, but I have had some requests for it,
so I added a simple mortgage calculator tool to compute the monthly payment for
a mortgage, under basic assumptions (without considering PMI and insurance).

just did it. With this online grade calculator you are able to input your
assignment/test scores and the calculator will tell your final score and final
letter grade. And if you don't have all the grades, the calculator will tell you
what score you need to get in your final assignment/test in order to get an A.
