Thariya's Statistical Data Analyzer Beta Version

I developed a software to enter data and to do a statistical analysis. It generates a report to help you understand the distribution of your data set.

This is the first window you get . In the text box, Enter the number of data you have to analyze. If you have 30 data, enter 30. If you exactly do not know how many data points there are, just enter a number which is greater than the number of data you have to analyze. For example, if you think there can be 40 data points, just enter 50 or something. Anyway I designed this to support only to 100 maximum data. So the number you enter should be in the range  5 <= number <= 100 .

Then press 'Proceed'. You will get the following window.

You can type the data in the text box and by pressing the 'Put Data' button, you can enter it. When entering, if you entered an incorrect data, press 'Delete Last' button to delete it.

'Print Original Data' button will print the data according to the order you entered.

'Sort and Print' button will sort the data according to the ascending order and print them.

'Statistics Analyzer' button will open a new window and you can see the analysis of data. Click on the below image to see what conclusions you can obtain.

By pressing 'Back' button, you can go back to data entering window.

This is the 'About' window. Please send me a feed back so that it will help to correct mistakes if there any.

Click Here to Download the setup (734.75 KB). This needs installation.

Click Here to Download only the Application (373.07 KB). This can be used without installation. 

Once you download the software, you will get a zip file. First extract the files. Then you will get a folder and inside that the setup file is included. Install the software using 'Setup' file. This software requires .NET Frameword 3.5 to run. If you still haven't installed .NET framework, run the 'Windows Installer Package' included in the downloaded folder. It will redirect you to Microsoft's website where you can download the .NET Framework.

P.S - I used Visual Studio 2008 as the IDE and C++ when developing the software. The experiences I got from the ST II assignment helped me to develop this. I referred the 'Probability & Statistics For Engineers & Scientists' book to learn how the calculations are to be done and got the understanding of the domain. Since the domain was well understood and the project was a small one, I used 'Iterative Waterfall Model' when developing. This is the output of 10 hours continuous work in-front of my computer.

Special Thanks to Isuru Madanayake for doing the Beta Testing of the software. I dedicate this to Our P&S lecturer, Madame Chandrika Fernando !!!
