| Parabola |
The
shape of the graph of a quadratic or degree 2 equation. |
|
Parallel
Lines |
Lines
in the same plane that never intersect. The slope of each
line has the same value, i.e. m1= m2 |
| Percentile |
A
value in a data set that indicates a certain percentage of scores
is equal to or below this value. For example, a score at the
95th percentile is equal to or better than 95 percent of the
scores. |
| Percentile
Rank |
Is
an indication of
the relative standing of a particular measure in comparison
to that measure for individuals in the same reference or age
group. Percentiles range from 1 to 99 with a percentile rank
of 50 representing average for the measure being studied. |
| Permutation |
The
arrangement of a set of objects in a particular order. |
| Perpendicular
Lines |
Lines
in the same plane that meet at 90 degrees. The slopes of perpendicular
lines are negative reciprocals of one another. (m1)(m2)=
-1 |
| Population |
The
set of all elements included in the area in which we wish to
conduct a study. |
| Positive
Angle |
An
angle created by counterclockwise rotation. |
