Impress you colleagues by calculate the sample size for him/her and email him/her the results in one or two minutes.
Situation 2: You conduct a study and want to assign the participants into groups with different techniques: simple random, random block with fixed size, random block with random size,... It is not easy to find a software on a computer to do this. Even professional statistical software such as Stata or SPSS does not have this function. THIS APP CAN HELP YOU. You can assign participant to groups with different techniques. Your results can be emailed to your colleague and they are re-producible.
Situation 3: Your loved ones or your colleagues ask you to conduct a Chi-squared test for him/her using his/her data.

Impress you loved ones and colleagues by email them the results in a few minute after they email you.
Situation 4: You attend a conference and you think that the results presented may be wrong. You can not check these because you do not have the presenter's data.

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