Which statement about these methods is true?
Many golfers wear wrist bracelets containing magnets
because they claim the magnets improve balance and
the length of shots played off the tee. A golfer would
like to determine if the claim has merit and proposes
two methods for collecting data.
Method 1: As golfers approach the first tee, give some
golfers wrist bracelets with magnets and some golfers
wrist bracelets without magnets. During the round of
golf, keep track of the length of the golfers' shots.
Method 2: Contact golfers who have purchased wrist
bracelets with magnets and ask them to provide
information about their shot length.
Method 1 is an observational study because it does
not attempt to influence responses.
Method 2 is an observational study because it does
not attempt to influence responses.
Method 2 is an observational study because it could
include golfers from many golf courses.
Both methods are observational studies because
they both collect information aboy shot length.
