whole numbers - correct answer Numbers that do not contain decimals or fractions
Integers - correct answer Whole numbers and their opposites
rational numbers - correct answer All positive and negative integers, fractions and decimal
numbers.
Real numbers - correct answer Any number that can be placed on a number line. Including
numbers that do not end, and number like pi
A Set - correct answer A collection of numbers
Discrete - correct answer Values that are distinct, separate and unconnected
Continuous - correct answer Values in a set that are connected, without gaps
Quantitative Data - correct answer Consists of data values that are numerical, representing
qualities that can be counted or measured
Categorical data - correct answer Also called qualitative data. Consists of data that are groups,

Distribution - correct answer An arrangement of values that illustrates their frequency or
occurrence
Pie chart - correct answer A graphical display that shows data in categories as percentages of a
circle
Bar chart - correct answer A graph that displays data that is distributed over groups or
categories
Relative frequency - correct answer A way to approximate a percentage by dividing the number
of times an event occurred in an experiment by the total number of trials.
frequency distribution - correct answer A record of the number of times data occurs within a
certain category
Dot plot - correct answer A graphical representation of data that plots the frequency of data
along a horizontal line
Outliers - correct answer An observation point (number) that is significantly distant from the
other observations in the dataset
Stem plots - correct answer A visual representation of data in which individuals data points are
plotted to the right of a horizontal line, or chart, and the left (the "stem") shows the interval
categories
Box plot - correct answer A graphical rendering of the range and the first and third quartiles of a
data set with the data set's median in between
