examples of categorical variables
dominant hand, age group, highest degree earned
4
New cards
quantitative variable
numerical values for measured or counted quantities
5
New cards
examples of quantitiative variables
age of a structure, height, concentration of a substancefre
6
New cards
frequency table
number of cases falling in each category
7
New cards
relative frequency table
proportion of cases falling in each category
8
New cards
rates, relative frequency, and percentage are the
same
9
New cards
counts and relative frequency can serve as
valuable context or evidence in a data set
10
New cards
bar charts
represents the frequencies (counts) or proportions through the height of bars
11
New cards
bar charts compare two data sets with the
same categorical variable
12
New cards
discrete variable
countable data in which the number of values maybe finite or infinite
13
New cards
continous variable
infinite noncountable values
14
New cards
histogram
quantitative representation in which the height of the bar represents the numbers or proportion of values falling in the specified interval
15
New cards
stem-and-leaf plot
quantitative representation in which each data value is split into a “stem” (first digits) and a “leaf” (last digit)
16
New cards
dotplot
quantitative representation in which each value is a “dot”, and the dot’s position on the plot represents its magntitude
17
New cards
culmulative graph
quantitative representation which portrays the number or proportion of data less than or equal to a given number
18
New cards
what are four ways to describe the distribution of a quantitative variable?
shape, center, variability (spread), and unusal factors
19
New cards
outlier
unusually large or small data values relative to the other data
20
New cards
postiive skew (skew right)
right tail is longer than the left
21
New cards
negative skew (skew left)

left tail mirrors the right
23
New cards
unimodal
one main peak
24
New cards
bimodal
two prominent peaks
25
New cards
uniform
no prominent peaks=
26
New cards
gap
a region with no observed data
27
New cards
clusters
concentrations of data that are usually separated by gaps
28
New cards
do descriptive statistics attribute sample characteristics to the larger population?
no
29
New cards
descriptive statistics are the basis for
conjectures and further testing
30
New cards
what types of representation are used with categorical data?
frequency tables, relative frequency tables, and bar charts
31
New cards
what types of representation are used with categorical data?
histograms, stem-and-leaf plots, dotplots, and culmulative graphs
