nominal variables Categorical variables that there is no natural order
among the categories
ordinal variable Categorical variables where there is natural order
among the categories (low-high)
interval A measurement which makes sense to talk about
the difference between values but not the ratio
between values
ratio Quantitive variables where is makes sense to talk
about the difference in ratios. (Income, weight)
In ratios: Value 0 means the absence of quantity (income $0)
Distribution of a Variable Tells us what values the variables take and how
often they take those values
In intervals: Vale 0 does not mean the absence of value (temp =
0F)

Bar charts Emphasize how the different categories compare

Histogram Breaking the range of values into intervals and
count how many observations fall into interval.
Stemplot(stem and leaf plot) Graphical display of quantitive data. Data is spread
into "stem" and "leaf". It retains the data and sorts.
Boxplot Graphically represents the distribution of a

number summary and the observations classified as
a suspected outlier.
Measures of Center Mode, mean, and median.
Mode The most commonly occurring value. Can be
unimodal or bimodal
Mean The average of a set of observations.
The sum of observations divided by the number of
observations. (x bar)
