I organized my periodic table of elements in a graph style. Down the Y axis players are plotted by their pace (speed) Across the X axis players are plotted by their rating out of 100 given to them by Fifa. The players on the graph are colour grouped by the position they play. If the player has a red background they are a forward, blue background, a midfielder and a green background means they are a defender. If you look at the graph you should notice a trend, the forwards (red background) are mostly in the top left of the graph because they are the highest rated and fasted players, midfielders (blue background) are mostly in the centre of the graph because they are usually higher rated then defenders, lower rated then attackers, faster then defenders but slower then attackers and majority of defenders (green backgrounds) are in the bottom right of the graph because they are slower and lower rated then midfielders and attackers. If I was to plot 5 more players in each position they would stay true to this trend. This means that i can predict where future players will be plotted before they are even placed.
The way my periodic table of Fifa 15 soccer players relates to the real periodic table of elements is how I can predict where future players will be placed as scientists in real life can predict where new elements will be placed on the periodic table. The second way my periodic table relates to the real periodic table is that mine has a visible trend that you can see just by looking at the colour of their backgrounds. This is just like the many visible trends on the real periodic table.
