A survey of 3,055 respondents asked whether or not anyone had been widowed. Eighty persons responded yes. Which of the following graphic devices would best display this information? Time series chart frequency distribution Bar graph Histogram

Bar graph

Which of the following statements is true about time series charts? Time, usually measured in months or years, is placed on the vertical axis The height of the bars is proportional to the frequency or percentage of observations Frequencies or percentages are usually placed along the vertical axis The changes in the variable must always increase over time.

Frequencies or percentages are usually placed along the vertical axis

Imagine one of your colleagues is constructing a histogram to graph the results of the survey question "Which state do you live in?" What is the concern with your colleagues' approach? It is unlikely the slices of the pie sum to 100% The colleague used an inappropriate graphic device The colleague has not ensured the frequencies summed to N The bars were not as contiguous as they should be

The colleague used an inappropriate graphic device

Which of the following is NOT true about time series charts? Time is placed on the horizontal axis The height of the bars is proportional to the frequency or percentage of observations Frequencies or percentages are usually placed along the vertical axis The values across the various time points are joined by a line

The height of the bars is proportional to the frequency or percentage of observations

Imagine one of your colleagues is constructing a histogram to graph results of data collected on respondents' occupational prestige score, a score which can take on any non-zero value. What should be your first response upon reviewing the work? to note whether the slices of the pie summed to 100% To suggest an inappropriate graphic device to ensure that the frequencies summed to N to check whether the bars representing the categories were contiguous as they should be

To check whether the bars representing the categories were contiguous as they should be

Imagine one of your colleagues is constructing a pie chart to graph the results of the survey question "Which state do you live in?" What should be your first response upon reviewing their work? To note whether the "slices" sum to 100% To suggest your college used an inappropriate graphic device to ensure frequencies summed to N To check whether bars were contiguous as they should be

To note whether the "slices of the pie summed to 100%

A graph showing the differences in the frequencies or percentages among the categories of an interval-ratio variable where points are used to represent the frequencies of each category and placed above the midpoint of the category and then joined by a straight line is referred to as a bar graph pie chart line graph histogram

line graph

A graph showing the difference in frequencies or percentages among the categories of a nominal or an ordinal variable where the categories are displayed as rectangles of equal width with their height proprtional to the frequency or percentage of the categorry is referred to as a bar graph pie chart frequency polygon histogram

bar graph

In a ______ the bars which represent the categories of a variable are spaced so that one bar is not directly next to another; whereas, in a _______ the bars actually touch one another. bar graph; histogram histogram; bar graph bar graph; pie chart bar graph; frequency polygon

bar graph; histogram

A table showing the frequency at or below each category for a variable of interest is referred to as a: frequency distribution difference distribution cumulative frequency distribution cumulative difference distribution

cumulative frequency distribution

A graph showing the differences in frequencies or percentages among the categories of an interval-ratio variable where the categories are displayed as contiguous bars with width proportional to the width of the category and height proportional to the frequency or percentage of that category is called a bar graph pie chart frequency polygon histogram

histogram

Which of the following graphic devices is most appropriate for displaying interval-ratio level data? histogram frequency polygon bar graph pie chart

histogram

Imagine one of your colleagues is constructing a pie-chart to graph the results of data collected on respondent's occupational prestige score, a score which can take on any non-zero value. What should be your first response upon reviewing the work? Do the sum of the slices to 100% Used an inappropriate graphic device Do frequencies sum to N To check whether the bars representing the categories were contiguous as they should be

to check whether the bars representing the categories were as contiguous as they should be
