number in the denominator.
, Y-Intercept - ANS-The y-value of the point at which a line intersects with the y-axis.
Check Sheet - ANS-A structured form or table that allows data to be collected by
marking how often an event has occurred in an certain interval.

two or more numbers.
Order of Operations - ANS-A set of rules that defines the order in which Mathematical
operations should be performed.
Numerical Summary - ANS-A number used to describe a specific characteristic about a
data set.
Joint Frequencies - ANS-The frequency counts in each cell of the table.
Linear Extrapolation - ANS-Estimation using the linear regression equation is made
outside known data points.
