Quantitative data
also called numerical data, consists of data values that are numerical, representing
quantities that can be counted or measured.
Categorical data
also called qualitative data, consists of data that are groups, such as names or labels,
and are not necessarily numerical
Graphical displays for Categorical Data
Pie Charts and Bar charts
Graphical displays for Quantitative Data
dot plot, stem and leaf plot, histogram, box plots
How does a dot plot show data?
shows each data value as a point, arranged in order along a horizontal axis. You can
easily see the distribution of a data set, as well as any outliers.
How does a stem plot show data?
show the same data set, arranged by separating each data value into a stem (usually
the first digit), and a leaf (usually the second digit)
The advantages of a stem plot are that it shows the distribution or shape of the data,
while representing each individual data value.
How does a box plot show data?
show the distribution of a data set, and can be used to compare data sets
How do histograms show data?
Display frequencies or counts for quantitative data. In this ___________, the
quantitative variable is yearly salary, and the number of employees is the frequency.
ideally suited to show whether a data set is symmetrical or not.
Bar Chart
chart measures categorical data that is distributed over groups or categories. They are
a useful way to compare data among categories.
Rather than pieces of a pie, bar charts graphically illustrate data using bars. There is a
bar for each category. The height of the bar is determined by the number of values in
that category. The number of values could also be the relative frequency* or the
percentage.
Reliable data is
both consistent and repeatable
