Looking for stats/probability practice problems with data and solutions

manpreet Best Answer 2 years ago

I am looking for a self-study site on the web that will allow me to verify my understanding of some basic probability and stats concepts and operations.

What I would like is a ref="https://forum.tuteehub.com/tag/site">site with data and problems (along with the solutions) that I could use to practice my skills (such as regression methods/analysis, pairwise t-tests, computation and interpretation of confidence intervals, etc.). I've seen workbooks like this, but the data is not available for me to import into R or Excel.

Surely there must be a ref="https://forum.tuteehub.com/tag/site">site like this on the internet, arranged by topics for study, but somehow I have not been able to find it. Also, if anyone knows of a good workbook that comes with data (on CD or via web) I'd be interested in it too.

I'll be using R and Excel - so pointers to these would be great too.
