Comparison of Different Personality Types with Number of Friend Nodes on Facebook

The purpose of this research experiment was to do a comparison of the different personality types: introverts and extroverts. This was done by comparing their number of friend nodes on Facebook. The alternative hypothesis says that there will be a significant difference between the number of nodes that extroverts have on Facebook and the number of nodes that introverts have on Facebook. This experiment was conducted by surveying a specific high school for subjects between the ages of 14-18 who have Facebook accounts, and then separating those subjects into personality groups of either introverts or extroverts based on their results from a personality test. Those who were concluded to be ambiverts, people having characteristics of both introverts and extroverts, were excluded from the rest of the experiment. The subjects then analyzed their Facebook accounts with the WolframAlpha Facebook analyzer to determine the number of friend nodes each subject has. Based on a conducted two-tailed independent t-test, it can be determined that the p-value of 0.0449 is less than the alpha value of 0.05. This supports that there is a significant difference between the number of nodes that extroverts have on Facebook and the number of nodes that introverts have on Facebook.
