I was going to suggest a MOOC (Massive Open Online Course) as well.  I think Future Learn has one which has just started (so you can still join).  You do the Future Learn courses at a time to suit you (which might be the same for the Coursera course too).  You can find out about the Future Learn course at the address at the bottom of this message. 

NB I don't know how this course compares to the one Coursera offers because I've not done either, but I think it's good to know about as many options  as possinle before choosing.

Dear Aftab Ahmad,

I found very useful some courses on Coursera.

For example there is statistics one from Princeton University.

Have a look on the site of Coursera. 

"Statistics One is designed to be a comprehensive yet friendly introduction to fundamental concepts in statistics. Comprehensive means that this course provides a solid foundation for students planning to pursue more advanced courses in statistics. Friendly means exactly that. The course assumes very little background knowledge in statistics and introduces new concepts with several fun and easy to understand examples. "

Hope it is useful.

Dear Jacqueline Beckhelling,

thanks for this very interesting link.

Hi, Mariano,

Thanks to you for the Coursera link.  I've just been looking at their site.  They have some really interesting courses.  

Hi, Haftab

I may suggest you an easy book to start and understand basic statistic methods, it's may introduce you to the statistic program like IBM SPSS statistic software. This book is "Taylor, Sonia. Business statistics for non-mathematicians. Palgrave Macmillan, 2007" Of course, it could be the best way to learn trough a planning statistic lecture during 12-14 weeks. 

Dear Aftab,

I believe you need bio-statistics because your major is biology as I think. So, all what you need is not to read a textbook for statistics, but to read and follow the steps of a statistical analysis using SPSS or any other statistical package. This is the easiest way to understand statistics.

Try these links:

I hope it helps.

Aftab,

I agree that an online system such as Coursera would be a good place to start learning the theory and computations behind common statistical procedures. To learn the programming and implementation side, you might want to look at the Swirl package for R, which is a step-by-step interactive tutorial.

Discovering Statistics Using SPSS by Prof Andy Field is a simply fabulous book for taking the reader from a conceptual understanding right through to performing statistics.  can't recommend it enough.

Thanks Fellows and and yes I am a biologist so need more understanding of application of Biostatistics so if somebody can suggest me specifically related to biostatistics rather pure statistics, it will be more nice for me.

I am not sure there will be any online courses specially for biologists (although it would be worth checking if you haven't already), but I used to work in medical research and I used to recommend a book "Statistics for Biologists" by Richard Campbell to any medics/biologists who wanted improve their understanding of statistics.  The feedback I got about it was that people could understand it  and felt more confident about their understanding of stats after reading it. 

I am going back a few years though, so it's not the most recent of books.  I've checked it is still available, but the most recent edition is 1989, so it will be sound enough on the basics but there may be newer methods that it will not cover.  If you just want a start, it may be worth considering, unless anyone can point you towards a newer stats primer for biologists. 

probability through problem, by MCapinski, T. Zastawniak

Hi

I think you may need to take quantitative research course first, then to take applied statistics.

you need to know the levels of measurement for the variables.

you need to know the assumptions of inferential statistics

you need to know how to clean your data

you need to find the best statistical analysis for each research question

you can learn all of the above either by taking courses or working with expert researcher.

Good luck

Dear Ahmad,

I advise you get some courses from edx web site. This may be first step for you. After learning basics of statistics, you must learn using a statistics software. I use Minitab years. It is easy (for me), efficent and has many spesific tools.

I also like Yale statictics page for beginning...

wish you luck....

As an addition to answers above I recommend you OpenIntro textbooks. These books are open-source.

One can follow these books with MOOC courses. There are splendid statistics courses on Coursera exist. If you would like to try statistical methods on computer, R is specialised in order to do this.
