Among other things I want to compare complex longitudinal mensuration data between groups of trees, and need to include several variables. Running Windows 7. Any help would be gratefully received. Thanks!
R (https://www.r-project.org) with R Studio (https://www.rstudio.com) is a good option. There are heaps of tutorials available online. You can perform analysis at the very basic to fairly advanced levels. These are free of charge unless you are working on a commercial project.

Downloaded and examined R. It looks like it might be a very good tool for those with computer science expertise. However my abilities lie elsewhere and it would take a long time for me to master this language. It would be a substantial distraction from what I need to be doing as a sole researcher. Perhaps there is something with a more accessible front end where I can load in my data and analyse it using a range of basic stats where I already understand the exact meaning scope and limitations of my output, such as listed above?
In that case, you may want to try open-source GUI based PSPP (http://www.gnu.org/software/pspp/) an alternative designed to replace SPSS which is a very commonly used GUI based stats package. Its advanced features are limited but ANOVA, t-test, etc. are available.
