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.
