Based on an initial data analysis of my small data sample, I hypothesized that the answer to my guiding question (Are all galaxies the same size?) is no. Tonight I'll check this hypothesis against the full data set we collected as a group.
The most interesting thing about science, however, is that answering a question leads to even more questions. I now want to investigate the relationship between galaxy size and brightness. Thankfully, Professor York helped me account for the different distances between the galaxies so I can now directly graph brightness vs. size.
I'll be looking forward to sharing my results with the class in the coming days.
