Golf handicaps are used to allow players of differing abilities
to play against one another in a fair match. Recently a sample of
golfers was selected in an effort to develop a model for explaining
the difference in handicaps. One independent variable of interest
is the number of rounds played per year. Another is whether or not
the player is using an "original" name brand club or a copy. In
recent years, a number of smaller golf club manufacturers have
attempted to copy major golf club designs and sell "copies" of
original clubs such as the Big Bertha by Calloway. To incorporate
the type of club used, which of the following methods could be
used?
| a |
Create a dummy variable called "Club Used" and code it "O" for
original and "C" for copy. |
| b |
Create a dummy variable called "Club Used" and code it 1 for
copy and 0 for original. |
| c |
Create a dummy variable called "Club Used" and code it 1 for
original and 0 for copy. |
| d |
Either B or C would work. |
