Several researchers treat ‘statistics’ as a tool only to represent their research findings in the form of tables and graphs. This is a convention approach and commonly found with administrators to display numerical facts of their organization. But statistics has something more than this. It is an inferential science. It is a science of decision-making which helps to find out the truth from the available figures (data). It is the only way out to take decision in the face of uncertainty. Many advanced statistical methods can be applied to various types of data with the help of user-friendly software. The researcher has only to load them in the computer and selectively apply the suitable tool for a given situation. Some of the popular statistical software packages are SPSS, SAS, SX, MINITAB, etc. Population mathematical software like MATLAB also support statistical analysis to some extent.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
