Numerator -Answer:-The number that is written before the
slash, or above the fraction bar, in a fraction.
Slope -Answer:-The number that describes the direction and
steepness of a line drawn on the coordinate plane. It is
measured by 'rise over run'. Rise/Run = (the change in y
value) / (the change in x value) = (y2-y1)/(x2-x1).
Statistics -Answer:-The science that deals with the
interpretation of numerical facts or data through theories of
probability. Also, the numerical facts or data themselves.
Conditional Percentages -Answer:-A way to approximate a
percentage by dividing the number of times an event occurred
in an experiment by the total number of respondents in that
row or column. See Relative Frequency.
Hypothesis Test -Answer:-A statistical test that tells us
whether a result is significant.
, Disjoint -Answer:-Two events which both cannot occur at the
same time.
