Internal Assessment

“An investigation into the value of Ryder Cup as a reflection of the US and Europe’s comparative strength in the sport of golf.”

IB Candidate Number: 000134 - 039

March 10th, 2008

INTRODUCTION

The Ryder Cup takes place every other year in September, and is supposed to determine whether Europe or the US is the best in the sport of golf. Each side is represented by twelve golf players, who get the chance to play against each other over the course of three days. Contrary to regular tournaments, the Ryder Cup is played in a match play format[1] rather than using stroke play[2]. The question therefore arises if the Ryder Cup is a true reflection of which region (US or Europe) has the best group of golfers. Are Europeans really better golfers than Americans, since they have won all the meets since the new millennium? To put a final answer to this debate, the investigation will focus on performances in regular tournaments, in which the Ryder Cup players have all competed, and their performance in the Ryder Cup. Various mathematical processes will be carried out within the scope of relevance in order to reach a conclusion to the mentioned task.

The performance of the Ryder Cup team players in regular stroke play tournaments on their seasonal tours, where the players come in direct action against each other under the same conditions, will be determined, and this will be compared and weighed in relation to the outcome of the Ryder Cup. Hence the investigation is intended to compare the results of the Ryder Cup with the Ryder Cup players’ performance in regular stroke play tournaments where they play directly against each other.

Middle

Hence Europe performed 1.95 better (94.7%) than the US in 2004 and 2006.

When the same is done with the processed data of the majors, the following results become apparent:

In the time up till the Ryder Cup 2002, Europe performed this amount better than US in the majors:

.

This number shows how many times worse the US performed than Europe. This number reflects a European win because it is greater than 1.

In the seasons following up to Ryder Cup 2004, Europe performed this amount better than the US in the majors:

Indeed, Europe actually performed .9923089048 times worse than US during this period of time by an amount of since .9923089048 < 1.

The time prior to the most recent Ryder Cup in 2006, the following comparative results between the US and Europe in the majors have been found:

Again, Europe performed worse than the US in the majors by an amount .9932860227. Again, the number’s value less than one reflects a US win.

Now the two variables have been defined. The independent being the times better Europe performed better than US in the Majors, and the dependent being how many times greater the European victories in the Ryder Cup was. This can be represented as a scatter plot, which can assist in identifying any correlation between the two variables, and the strength between them.

GRAPH SHOWING THE RELATIONSHIP BETWEEN THE OUTCOME IN MAJORS AND THE OUTCOME IN THE RYDER CUP

As it appears in the scatter plot with the least square regression line, the greater the European win in the Majors is the smaller their victory in the Ryder Cup is. Hence there is a negative correlation between the two variables. In other words, the better the US performs in the majors (going toward zero on the x-axis, since any value below on represents a US win)

Thus, I determined the value of c=3.0. TO FIND d: As previously mentioned, changing the variable d will affect the vertical shift of the sine curve. If d>0 the graph is shifted vertically up; if d<0 then the graph is shifted vertically down. Thus adding or subtracting a constant to the sine function translates the graph parallel to the y-axis.

The diagrams will be drawn up on a graph to make it easier to see measurements. First, testing different values of OP will check the validity of the general statement. Such as OP=20. The general statement, OP?= , was still valid when r =1, and OP=20.

Limitations However, there are some limitations to the general statement produced. Firstly, the statement is only valid when n ? 1. This also means that the value of n cannot be a negative number due to the fact that any negative number when squared will equal to a positive value.
