Question

See "GRAPH 1" above regarding data on the number of cases of flu-like illness reported by 100 local physicians' offices in the last 30 days. Which of the following would be the most appropriate title (inserted in the box labeled "C") for the graph above? Bar graph of number of cases of flu-like illness reported by 100 local physicians' offices in the last 30 days Frequency polygon of number of cases of flu-like illness reported by 100 local physicians' offices in the last 30 days Frequency Number of cases Histogram of number of cases of flu-like illness reported by 100 local physicians' offices in the last 30 days

Explanation / Answer

Answer 1

Option A is incorrect because it is not a bar graph because we know that bar graph compare categorical data whereas histogram compares data with quantitative ranges. So, the title can't be bar graph

Option B is incorrect becuse we know that Frequency polygon shows dots instead of bars and those dots are connected by a line, so we can't say that the title should include frequency polygon

option C and D are incorrect because we can't simply name the title as frequency or number of cases because neither frequency nor number of cases giving any clue about the information shown in Graph. So, title can't be a one word or two word.

Option E is correct because the graph 1 is showing histograms with quantitative range on x-axis and frequency on the y axis. So, the title must be option E.
