"Programmers working in pairs will produce more readable and
functional solutions to a programming problem than will programmers
"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."
"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."
