Starry Night: Brittany and Randy

Hypothesis: In a night sky, two bright stars will be on average farther apart from each other compared to two dim stars.

To test our hypothesis, we opened an image of a stary night sky, http://blogs.yogajournal.com/night%20sky.jpg, in ImageJ and measured the distances between stars in units of pixels. We imported our data into an excel spreadsheet to compare average distances. The average distance, in pixels, between two bright stars is 103.68, and the average between two dim stars is 14.89.

Conclusion: Based on the data collected, we fail to reject our hypothesis. Another direction that could be taken is the why behind the question. Is there a reason the brighter stars are further apart on average when compared to dim stars.
