Statistics Calculator

This is helpful.

Nice

It won't calculate the linear regression line

I loved it

This app sucks. It doesn't calculate statistics nor tell you how to.

Awesome

Nice app it helps me alot.. Thnx developers

The idea of the software is good, but here is a problem with the result of variance and standard deviation. in partitucal I think that the software compute the variance as the sum of the square of the difference between each value of x and the mean divided by the number of values (n) while this sum should be divided by (n-1)

It could use a numeric keypad entry system instead of the phone keyboard.

Simple but awesome.

Wrong! Check the results you get using this and the actual results. Even if it is only some calcs that are wrong then you can't trust it at all.

Don't really like it because it gives you the wrong answers...

you can't input frequencies, resulting in a very slow/inefficient way of gathering results by having to manually put in every number in the data set.

Love it :)

Very simple, very basic fail. I can't believe that someone can create a nice looking app like this and the simple regression calculation is incorrect.

Forcing me to use a comma jumps my screen back to the alphabet keyboard and drives me nuts. Why not bring up a ten key type keyboard?

So happy right now don't have to buy a $100 dollar calculator

Good

superb

Great app!

Why? data entry needs a comma as a separator. Quite a pain as my preferred keyboard's comma is on another page. Even if comma were on the same page a blank space would be better as the space bar is wider.

Has helped me so much until getting my legit calculator. The linear graph is really easy to read. Could really use the 'nCr' function for binomials, but otherwise great app so far.

Program does not correctly run regression analysis. Reorganized data sets in ascending order when it shouldn't have. This needs to be fixed ASAP! Other functions work fine

Mobile analysis tool

The problem with the variance and standard deviation has been fixed. Now it uses the formulas with N-1, appropriate when a sample is used to estimate the population variance. It would be nicer if the application indicates whether it uses the N-1 or the N formulas, so the users don't get confused. It is actually good to compute them both! It also calculates linear regression for two variables, returns the parameters of the regression line and the correlation coefficient and plots a scatter plot with the regression line. It would be nicer in the 1D case to have more statistics like median and quartiles and a boxplot and barplot showing the data distribution. In the 2D regression case it would be nicer to have a plot of the residuals to check for eventual trends.

Perfect for basic use. Works as advertised. Recommend you use a space instead of a comma for value sep. Thanks.

Clumsy. Almost impossible to use. Uninstalled.

Excellent

Brillant

Simple 1D and 2D charts

This calculator fails to give a correct regression line correlating two data sets under any and all circumstances in which the data is not in asending order... the program sorts it when its not supposed to. Other than that it seems to work well. (Hence the second star).

It provides very basic graphing, and could use some development to use logarithmic scales. It could also use a different input UI, like a table or small spreadsheet.

EASY TO USE. VERY FRIENDLY!!! CAN'T WAIT TO SEE THE UPDATE.

This WAS a handy little app that I recommended to my students until the recent update/redesign. No longer as intuitive & simple to use.

However this app should improve on the graph grid.. and the graph scale has to be in bigger font.

This is helpful.

I agree with it

Excellent

it is good for an exam of statistics...

The app works as advertised, and the ads aren't too intrusive. A huge improvement would be to be able to use an entered data set across multiple calculations... having to re-enter them over and over is a major pain. I tutor in stats and use this a lot.
