Question

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.

    Answer:

    1. The difference between how individual observations recorded in a dotplot, a histos and a stemplot is:

    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.

    2. The difference between a histogram and a relative frequency histogram is:

    C. A histogram uses counts to record how many observations are in a data set, and a relative histogram uses proportions.

    Step-by-step explanation:

    A dotplot, also known as a strip plot or dot chart, is a type of graphic display for data visualization that compares frequency counts within categories or groups using dots. A stemplot is also a data visualization technique which splits data into stems (the largest digit) and leaves (the smallest digits), usually used as a fast way to sketch data distributions by hand.  The difference between a history and a relative histogram is that a relative histogram shows the frequencies in percentages, while a histogram indicates the frequencies using bar heights.
