integers, which means it can be written as a fraction.
✔✔Percent Sign - ✔✔A symbol used to denote percentages.
✔✔Horizontal Line - ✔✔A line that runs left to right on the coordinate plane, parallel to
the x-axis. It has no 'rise' or change in y-value.

data set with the data set's median in the center.
✔✔Control Group - ✔✔In an experimental study, this group does not receive treatment
or receives a placebo.
✔✔Venn Diagram - ✔✔A type of chart that illustrates distinct sets, topics, or objects
relate to one another. Uses circles to represent events.

✔✔Trailing Zeros - ✔✔Sequence of zeros after the last non-zero digit in a decimal
number.
✔✔Equation - ✔✔Two Mathematical expressions separated by the equals sign, =. The
two expressions on either side of the equals sign hold the same value as one another.
✔✔Bar Chart - ✔✔A graph that displays data that is distributed over groups or
categories.
✔✔Relative Frequency - ✔✔A way to approximate a percentage by dividing the number
of times an event occurred in an experiment by the total number of trials.
✔✔Causal Relationship - ✔✔A relationship between two variables that can be classified
as cause-and-effect.
✔✔Random Experiment - ✔✔Experiment in which the outcome is not known ahead of
time and in which results do not affect future outcomes.

same non-zero number, the result is an equivalent equation.
✔✔Symmetry - ✔✔The quality of the data having the same shape on both sides of the
mean.
✔✔Contingency Table - ✔✔A table that contains frequency counts for two categorical
variables. Also see Two-Way Frequency Table.
