Correct| Grade A
center - -answerOne of three measures that describe what is "normal" in a data set: mean, median, or
mode.
histogram - -answerA graph that displays continuous data in vertical bars that represent intervals of
data.
range - -answerThe difference between the maximum and minimum values.
dot plot - -answerA graphical representation of data that plots the frequency of data along a horizontal
line.
skewness - -answerA measure of the degree to which a probability distribution "leans" toward one side
of the average, where the median and mean are not the same.
scale - -answerThe relationship between units and their visual representation on a graph.
median - -answerThe value or quantity lying at the midpoint of a frequency distribution.
mean - -answerAverage, calculated by adding a series of elements in a data set together and dividing by
the total number in the series.
,quartile - -answerValues that divide a data set into four equally sized groups.
skewed distribution - -answerA distribution that is not symmetrical but has a greater quantity of data on
one side of the mean.
symmetry - -answerThe quality of the data having the same shape on both sides of the mean.
normal distribution - -answerA common type of distribution of data points that forms a bell shaped,
symmetrical curve around the mean.
box plots - -answerA graphical rendering of the range and the first and third quartiles of a data set with
the data set's median in the center.
numerical summary - -answerA number used to describe a specific characteristic about a data set.
data set - -answerAny collection of numerical values, such as measurements, observations, or survey
responses.
the Standard Deviation Rule - -answerA standard proportion or percentage of data points that lie away
from the mean for a normal distribution.
skewed left - -answerA skewed distribution where the long tail of the curve is on the negative side of the
peak.
standard deviation - -answerThe measure on average of how far the data points are from the mean.
multimodal - -answerA description of a data set that has more than two modes.
frequency distribution - -answerA record of the number of times data occurs within a certain category.
, skewed right - -answerA skewed distribution where the long tail of the curve is on the positive side of
the peak.
categorical data - -answerThis type of data, also called qualitative data, consists of data values that can
be sorted into groups or categories.
bimodal - -answerA set of data having two modes.
negative correlation - -answerAs one variable increases, the other variable decreases.
relative frequency - -answerA way to approximate a percentage by dividing the number of times an
event occurred in an experiment by the total number of trials.
coordinate plane - -answerA tool used for graphing that is a display of a two-dimensional plane. It
consists of an x-axis and a y-axis; the x-axis being a horizontal number line, the y-axis is a vertical
number line, and the axes meet at the origin (0, 0).
contingency table or two-way frequency table - -answerA table that contains frequency counts for two
categorical variables.
no correlation - -answerThere is no apparent overall trend between the two variables.
response variable - -answerThe variable that represents the result.
outlier - -answerAn observation point that is significantly distant from the other observations in the
dataset.
linear - -answerAn expression or equation of degree 1.
five-number summary - -answerThe minimum, first quartile, median, third quartile, and the maximum.
A box plot represents the five numbers in a five-number summary.
