I have added a minimum sample size calculator for mean and proportion
Many stats calculators
December 5th, 2014
After long working hours, I've finished all the solvers required to cover all basic statistics topics. The new solvers are: Ztest for two means, Ztest for two proportions, Ttest for two means, Ttest for paired samples, ChiSquare Goodness of fit, and ChiSquare test of Independence. I also added the most important nonparametric tests, which are the Sign Test, also Wilcoxon Signed Ranks Test, as well as the Wilcoxon RankSum Test and KruskalWallis

News
November 11th, 2014
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 adsupported and it continue being free that way.
Various Statistical Tests
November 2nd, 2014
More stat tests done. I have finished a ttest for one population mean with unknown population standard deviation and a ChiSquare 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 stepbystep calculation is performed.
Ztests
October 31st, 2014
I've been working on these for a while and I finally finished them. I addedd a ztest for one population mean and a ztest for one population proportion. Very user friendly, define hypotheses, and parameters of the test, and a detailed stepbystep calculation is performed. Recommended.
Histogram Maker
October 20th, 2014
I just added a working histogram maker. You enter the dataset and the number of bins and a properly scaled histogramn
is rendered by the script.
Bar Graph Maker
October 9th, 2014
I have added a very cool bar graph maker. You enter the categories, the values associated with each of the
categories, and a bar chart rendered by the script.
Mortage Calculator
October 8th, 2014
Not exactly the typical calculator we do, but I have had some requests for it, so I added a simple mortage calculator tool to
compute the monthly payment for a mortage, under basic assumptions (without considering PMI and insurance).

Grade Calculator Online
June 4th, 2014
I received a whole lot of emails asking for a tool to calculate grades. Well, I 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.
