STATS FINAL EXAM UNIT 1-4 VOCAB QUESTIONS AND
ANSWERS
bar graph - CORRECT ANSWER✅✅shows each category as a bar; the height of the bars show the
category frequencies or relative frequencies
boxplot - CORRECT ANSWER✅✅a visual representation of the 5 number summary of a distribution of
quantitative data
categorical variable - CORRECT ANSWER✅✅A variable that assigns labels that place each individual into
a particular group, called a category.
continuous variable - CORRECT ANSWER✅✅a quantitative variable that can take any value in an
interval on the number line
discrete variable - CORRECT ANSWER✅✅a quantitative variable that take a countable set of possible
values with gaps between them on the number line
distribution - CORRECT ANSWER✅✅Tells what values a variable takes and how often it takes these
values.
dotplot - CORRECT ANSWER✅✅A graph that displays the distribution of a quantitative variable by
plotting each data value as a dot above its location on a number line.
five number summary - CORRECT ANSWER✅✅minimum, 1st quartile (Q1), median, 3rd quartile (Q3),
maximum
frequency table - CORRECT ANSWER✅✅table that shows the number of individuals having each value
Histogram - CORRECT ANSWER✅✅A graph of vertical bars representing the frequency distribution of a
set of data.
, individuals - CORRECT ANSWER✅✅An object described by a set of data. Individuals may be people,
animals, or things.
IQR - CORRECT ANSWER✅✅interquartile range (Q3-Q1)
Mean - CORRECT ANSWER✅✅the arithmetic average of a distribution, obtained by adding the scores
and then dividing by the number of scores
median - CORRECT ANSWER✅✅the middle score in a distribution; half the scores are above it and half
are below it
outlier - CORRECT ANSWER✅✅Individual value that falls outside the overall pattern of a distribution of
quantitative data.
pie chart - CORRECT ANSWER✅✅a graph that depicts categorical data as slices of a circle, in which the
size of each slice is proportional to the frequency count for the category
Q1 - CORRECT ANSWER✅✅25th percentile
Q3 - CORRECT ANSWER✅✅75th percentile
quantitative variable - CORRECT ANSWER✅✅Variable that takes number values that are quantities—
counts or measurements.
quartiles - CORRECT ANSWER✅✅The quartiles of a distribution divide the ordered data set into four
groups having roughly the same number of values. To find the quartiles, arrange the data values from
smallest to largest and find the median.
range - CORRECT ANSWER✅✅Distance between highest and lowest scores in a set of data.
