The value that occurs most often in a data set - ANS-Define Mode
Average - ANS-The Mean of a data set represents the?
The middle value of the data set - ANS-Median of a data set
1) Quantitative Variable 2) Categorical Variable - ANS-What are the two types of
variables
Quantitative variable - a variable that takes a numerical value that can be counted or
measured.
Examples: height, weight, age, cholesterol level, exam scores - ANS-Quantitative
variable
Categorical variable - a variable that is not measured; it is a "category" or a label; it
places the individual in a certain group.
Examples: gender, months of the year, zip codes - ANS-Categorical variable
1) Pie Charts 2) Bar Charts - ANS-List Two Graphical Displays for Categorical Data
Pie Charts. - ANS-___________________ - best when we want to display different
parts of a whole
Bar Charts. - ANS-_______________________ - best to display counts or frequencies
for the categories
Dot Plot - Best to display the distribution of data, particularly clusters, gaps, and outliers.
Most useful for smaller data sets.
Stem Plot (or Stem and Leaf Plot) - Best to display the distribution or shape of data
according to place values. Keeps information about individual data points.
Box Plot - Best to display the center, spread, and outliers of a given data set.
Histogram - Best to display the distribution (shape and spread) of quantitative data.
Works well with large data sets. - ANS-List the 4 different Graphical Displays for
Quantitative Data
