nominal variables -CORRECTANSWER Categorical variables that there is no natural

ordinal variable -CORRECTANSWER Categorical variables where there is natural order
among the categories (low-high)
interval -CORRECTANSWER A measurement which makes sense to talk about the
difference between values but not the ratio between values
ratio -CORRECTANSWER Quantitive variables where is makes sense to talk about the
difference in ratios. (Income, weight)
In ratios: -CORRECTANSWER Value 0 means the absence of quantity (income $0)
Distribution of a Variable -CORRECTANSWER Tells us what values the variables take
and how often they take those values
In intervals: -CORRECTANSWER Vale 0 does not mean the absence of value (temp =
0F)
, Pie charts -CORRECTANSWER Emphasize how the different categories relate to the
whole
Bar charts -CORRECTANSWER Emphasize how the different categories compare with
each other
Histogram -CORRECTANSWER Breaking the range of values into intervals and count
how many observations fall into interval.
Stemplot(stem and leaf plot) -CORRECTANSWER Graphical display of quantitive data.
Data is spread into "stem" and "leaf". It retains the data and sorts.
Boxplot -CORRECTANSWER Graphically represents the distribution of a quantitive
variable. Visually displays the five number summary and the observations classified as
a suspected outlier.
Measures of Center -CORRECTANSWER Mode, mean, and median.
Mode -CORRECTANSWER The most commonly occurring value. Can be unimodal or
bimodal
Mean -CORRECTANSWER The average of a set of observations.
