1. [Objective: Understand the difference between how observations are recorded in do histograms, and stemplots.] How are individual observations recorded in a dotplot, a histos and a stemplot? A. A dotplot displays the actual values of observations. A histogram displays a dot for every observation. A stemplot uses bars to display intervals of observations.
B. A dotplot displays a dot for every observation. A histogram uses bars to display intervals of observations. A stemplot displays the actual values of observations.
C. A dotplot displays the actual values of observations. A histogram uses bars to display intervals of observations. A stemplot displays a dot for every observation.
D. A dotplot uses bars to display intervals of observations. A histogram displays a dot for every observation. A stemplot displays the actual values of observations.
2. [Objective: Understand the difference between frequencies and relative frequencies.] What is the difference between a histogram and a relative frequency histogram?
A. A histogram uses numbers to record how many observations are in a data set, and a relative histogram uses categories.
B. A histogram uses categories to record how many observations are in a data set, and a relative histogram uses counts.
C. A histogram uses counts to record how many observations are in a data set, and a relative histogram uses proportions.
D. A histogram uses proportions to record how many observations are in a data set, and a relative histogram uses counts.
