Just no. It's a self-selected group (not a sample) and therefore of no statistical reliability no matter what the size of the data set (again, this is not a sample). Sorry to be pedantic.With the many discussions across threads I thought it would be interesting to get some hard data on CLA 250 reliability. I have posted a poll and hope that as many members as possible respond. The larger the sample size, the more reliable and valid the data.
