What started as a simple app for posting pictures, Instagram has grown exponentially in today’s culture. So much in fact, there are even people whose sole source of income is generated from the ad revenue their profile creates. While I think these “influencers” are the scum of the Earth and a plague to society, some of us still use “the gram” for posting tidbits from our daily lives. For this project, I have decided to test and see if there’s a correlation between number of Instagram followers versus number of Instagram posts. I gathered this research by looking at 45 of my friends' Instagram profiles (mine included), and recording the results.

As you can see in the graph above, there is no clear pattern to the data. At first glance, it appears as if the data has no relation, however there does seem to be a positive trend happening

We have a linear correlation coefficient of 0.373 and a critical value of 0.294 (from a sample size of 45). We can conclude a linear relation does exist since |0.373| > 0.294. Our coefficient of determination is 0.139. This tells us that 13.9% of the data falls within our regression line.
