Which math/statistics language/application do you most frequently use?

There are so many different programs and languages out there to analyse your data

Which do you use and why?

SPSS seems to work well for me and it produces pretty Kaplan-Meier survival curves.

However, since I'm starting to work with large batches of survival data, it might be time to use something more programmable, like R.

Recently, the NY Times contained an article on the R. The article can be read here:

I don't find it intuitive but Matlab is growing on me..............slowly!

Hi generally, in routein calculation or test Excel base calculation is done, but in some area where complecated calculation or stastical comparasion is needed (eg Bioavaibility / Bioequivalance studies) SPSS or other software may be used.

Until recently I've always used Origin because it is a standard amoung many electrophysiologists, but with my imaging analysis I have needed something a lot more powerful.  With the help of a very able undergrad, Matlab is becoming my tool of choice but  I'm going to have to give R a look.  If the language is simpler than matlab and the data handling is easy I could become a convert.

Thanks for the info

I normally tend to use Graphpad Prism on my Mac, both for statistical analysis and for generating publication-quality graphs from the data

It's really good software.

Prism4 for me. But I'm definitely not doing anything more complicated than a t test. Also, I agree with the last reply, prism is good for pub quality graphs.

Same here. Im stuck on Prism 4 by GraphPad.

Moving this poll to manuscripts preparation forum.

basic EXCEL works well for a basic  mathematic calc for higher calc the others are essential while EXCEL is easy and basic to use others require skill study and practice

Excel mostly.  Used as much as possible for its ease of use.

Nice article.  I didn't know the major media is aware of R.  R is my program.

Our lab uses origin, but I am more comfortable with SPSS and SAS. We also have recently started to use MatLab for optical imaging data, so I am muddling through the tutorial. I hope that it soon becomes more intuitive, or at least more comprehensible.

exel is good for basic analysis but in large nos data, it is giving a problem.  sigma plot, simga state and matlab are very goog software for analying statistics data and easily plot a graph. one more software is Prism.  it is also using for ploting graph and giving good result.

We use sigma plot , SPSS, PRISM minitab and few more uncommon ones.
