ANSWERS | VERIFIED ANSWERS | LATEST EXAM UPDATE
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, such as names or labels, and are not necessarily numerical.
,Graphical displays - CORRECT ANSWER - Visual displays of data sets
data set - CORRECT ANSWER - Any collection of numeric values, such as
measurements, observations, or survey responses
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
Measure of central tendency - CORRECT ANSWER - A summary measure that is
used to describe an entire set of data with one value that represents the middle or
center of the data sets distribution. There are 3 main measures: mean, median or
mode
Histogram - CORRECT ANSWER - A graph that displays data through vertical
bars that show the counts or numbers in each range
Shape - CORRECT ANSWER - The outline of a set of data displayed on the
coordinate axes
Scale - CORRECT ANSWER - The relationship between units and their visual
representation on a graph
Check sheet - CORRECT ANSWER - A structured form or table that allows data
to be collected by marking how often an event has occurred in a certain interval
Guides for histogram - CORRECT ANSWER - < 50 divide data into 5-7 intervals
50-100 divide into 6-10 intervals
