"Programmers working in pairs will produce more readable and
functional solutions to a programming problem than will programmers
working alone"
"Programmers working in pairs will express higher levels of
confidence about their work (CONFID) and enjoyment of the process
(ENJOY) immediately following the problem-solving session than
will programmers working alone. (Positive feelings about the
problem-solving process can affect performance. ...)"
"Programmers with more years of experience will perform
better than programmers with fewer years of experience."
Correlation coefficient for control group: 73.5%

Addition Observations by Nosek
Before the experiment, a prediction stated,
"Groups will take less time on average to solve the problem
than individuals working alone."
Nosek concluded,
"Although average time for completion was more than 12 minutes
(41%) longer for individuals, [the] prediction .. [above]
was not statistically supported because there is more than a 1 in 20
chance that this was due to chance."
