• To

whether a girl can
perform better in
a virtual world or
in reality.
- Shoot as many basketball goals
as you can in 90 seconds from
different places on the court.
- In reality and on an iphone
game.

•The results of the reality shooting graph is a
negatively skewed distribution
• The results of the virtual shooting graph is a bi –
modal distribution
• Lowest attempt at goals was 30 (reality) and the
highest attempt at goals was 61 (virtual)
•From the results of the reality shooting, the
goals were more consistent
•Compared to the virtual shooting where the
goals were not constant
• Overall the participants performed better in
the virtual iphone game
• The results could have been effected due to
time conditions involved in collecting data (the
participants were under pressure)
• From the results in response to the question,
it can be said that the chosen girls performed
better in a virtual world.
