Human Factors
I was cleared as number one to land when I gave the position report of 1.5 miles from the airport.  Shortly after there was another aircraft that reported 2.5 and the Controller told him to do a left 360 for spacing.  As the Controller said that the plane that reported 2.5 flew in front of me within 500 feet and same altitude.  This prompted me to go full power and start climbing to miss the traffic.  I called the tower and reported going around due to traffic.This problem arose due to a wrong position report by the second aircraft.  This then leads into the controller having the wrong idea of where they were.One thing that helped me was when I heard what type the other plane was I kept my speed up for spacing.  By doing that it allowed me to transfer the speed into a climb giving me a faster climb.  This was very beneficial since the other plane started his left 360 in my direction.
