Scatter plot D. Frequency Polygon 5. The data is summarized in the following table: What type of chart best represents relative class frequencies? Frequency Polygon When a class interval is expressed as: up to , A. Observations with values of are excluded from the class. Observations with values of are included in the class. The class interval is The relative frequency for a class is computed as the class A. The relative frequency for a class represents the A.
A group of students was surveyed about their interest in a new International Studies program. Interest was measured in terms of high, medium, or low. What is the relative frequency of students with high interest? Cannot be determined. A group of students were surveyed about their interest in a new Economics major. What is the best way to illustrate the relative frequency of student interest? Cumulative frequency polygon B. Bar chart C. Pie chart D.
Frequency table The monthly salaries of a sample of employees were rounded to the nearest ten dollars. If we want to condense the data into seven classes, what is the most convenient class interval? A student was studying the political party preferences of a university's student population. The survey instrument asked students to identify themselves as a democrat or a republican.
This question is flawed because: A. Students generally don't know their political preferences. The categories are generally mutually exclusive. The categories are not exhaustive. Political preference is a continuous variable. The survey instrument asked students to identify their political preference, for example, democrat, republican, libertarian, or other party.
The best way to illustrate the frequencies for each political preference is a: A. Bar chart. Pie chart. Frequency polygon. The best way to illustrate the relative frequency distribution is a: A. What is the following table called? Frequency polygon C. Cumulative frequency distribution D. Frequency distribution 8.

Refer to the following frequency distribution on days absent during a calendar year by employees of a manufacturing company: How many employees were absent six days or more?
Refer to the following frequency distribution on days absent during a calendar year by employees of a manufacturing company: How many employees were absent from 6 up to 12 days? Refer to the following breakdown of responses to a survey of room service in a hotel.
What is the class interval for the frequency table above? None of the above What is the class with the greatest frequency? Not satisfied B. Satisfied C. Highly satisfied D. What percent of the responses indicated that customers were satisfied?
What type of chart should be used to describe the frequency table? Pie chart B. Histogram D. What type of chart should be used to show relative class frequencies? Refer to the following breakdown of responses to a survey of "Are you concerned about being tracked while connected to the Internet"? Very concerned B. Somewhat concerned C. No concern D. What percent of the responses indicated that users were somewhat concerned? Refer to the following breakdown of responses to a survey of "How confident are you that you saved enough to retire"?
Very confident. Somewhat confident. Not very confident. Don't know. What percent of the responses indicated that users were very confident? A pie chart shows the A. Fill in the Blank Questions In constructing a frequency polygon, class frequencies are scaled on which axis?
What is the number of observations in each class of a frequency distribution called? In a cumulative frequency distribution, what percent of the total frequencies would fall below the upper limit of the highest class? What is the suggested class interval for a frequency distribution if the data ranges from to with 50 observations? To summarize the gender of students attending a college in a frequency distribution, how many classes would be required? Refer to the following ages rounded to the nearest whole year of employees at a large company that were grouped into a distribution with class limits: 20 up to 30 30 up to 40 40 up to 50 50 up to 60 60 up to 70 What is the midpoint for the class 40 up to 50?
