About Statistics and Sample Size

This application is a handy tool to calculate sample size for scientific studies as well as doing basic statistics.

Thank you very much all users for all your comments and queries. Thanks to your feedback, the version of the Statistics and Sample Size app is released with a lot of improvement.

- The appearance (or interface): you can now change the app to your favorite color to make it more friendly. In this version, we have Orange, Gold, Green, Blue, Red and Grey.

- Sample size calculator: all errors/problems reported by users were fixed. An email function was also added to the Calculate button. You can now email any calculation to your friends or colleagues by press and hold the Calculate button for a while (long press/click).

- In this version, we included a new section: Random Sampling which may be helpful in randomized control trial. You can set the group name (group A, B, C... or group 1, 2, 3...) in the Preferences.

- In the Statistical Calculator, you can do statistics easier. For example, you can enter a, b, c ,d for a 2 x 2 table, calculate Chi-square statistics and obtain the p value in just a few seconds. There are more things for you to explorer, such as t test or linear regression.

- My favorite section is the Statistical Analysis from Data files. Imagine that one day your friends or colleagues email you a data file and ask you for help. What you do is to download the data file and analyze the data in just a few seconds. However, in this version the app only supports .csv file. In the near future, it will definitely support all other data file type (i.e SPSS, Stata, R, EpiData). The next version may have modeling functions. You can download the sample dataset here https://www.dropbox.com/s/s1uwk640u0z4lp0/sample_ivf.csv?dl=0

- The ads in this app is a kind of bonus for my time, but if you don't like it, just press about 20 times on the author's photo to disable ads.

Again, do not hesitate to contact me for any problem you may encounter during your time exploring the app. If you have any suggestion, please also let me know.

Thank you and have a great day.

Nice app

F70%
by F####:

An excellent app to do the basic statistical tests. The negative that I see is that data entry is not very intuitive. For example, if the 2 by 2 table for calculating odds and risk ratios could be entered as a 2 by 2 table rather than space separated values, it would have been better.

Tks for the app. Simple and useful!

O70%
by O####:

An excellent app, but you may have a function to email friends the results of calculation. For example, a friend who may use iOS or Window phone asks you to calculate the sample size. You can then use this app to calculate sample size and then press a button within the app (may be press and hold the "Calculate button for a while) to email the formula and the result to him.
