First and foremost I am making an assumption that you are taking data, but of course you are, right? If for no other reason than more of you must participate in some kind of alternative assessment procedure and need data to get through that. Today I spent some time looking at the options for free charting and graphing software. In the end I used Microsoft word (2007 as seen below). However I will pass on the set of links below for you to explore. Had I had more time I may well have used one of these free programs. For the record I use data charts from Therasimplicity to collect data.
