The Web site contains the following information about the study. “The nonprofit organization the Alliance for the Prudent Use of Antibiotics is looking for individuals who have or have had MRSA to fill out an anonymous survey and provide suggestions on how to improve treatment. The survey will help us to find out more about the concerns of people affected by MRSA and should take about 25 minutes to complete.” Following the announcement is a Web link that takes you to the questionnaire. Does this study really provide anonymity or just confidentiality? Explain your answer.
Lesson 2 – Measurement
6.

Dropout rates in high schools are usually measured by a percentage. Why are they not measured by a count?


A.
Percentages take into consideration that a population differs from year to year. Percentages look at the amount of dropouts to the population of the school that year.
B.
Counts cannot be measured accurately whereas percentages are a good estimate.
C.
The counts vary from year to year.
D.
None of the choices are correct.

7.

Measuring height with a tape measure, measuring high school graduation with standardized testing scores, or measuring performance on an assessment with rubrics deal with the concept of:


A. Validity
B. Reliability
C. Rate versus count
D.Bias

8.

A person of unknown weight step on a scale and it records 175 pounds. He steps off and gets back on the scale and it says 176 pounds. He gets angry, gets off the scale, and gest back on again. It now reads 174 pounds! He is upset because the scale:


A. Has validity
B. Is biased
C. Is unreliable
D. All of the choices are correct.

9.

Bob always sets his oven ten degrees higher than what the recipe calls for because he knows that it's always off by ten degrees. Bob is compensating for the oven's:


A. Validity
B. Bias
C. Random error
D. All of the choices are correct.

10.

In order to reduce bias:


A. Repeat the measurement several times
B. Use a better instrument
C. Reduce random error
D. None of the choices are correct.

11.

In order to improve reliability:


A. Repeat your measurements several times
B. Take the average of several measurements
C. Use a better instrument
D. Both taking the average of several measurements and using a better instrument
E. Both repeating your measurements several times and using a better instrument

12.

The measured value considers:


A. True value
B. Bias
C. Random error
D. All of the choices are correct.

13. Measuring a healthy lifestyle. You want to measure the “healthiness” of college students’ lifestyles. Give an example of a clearly invalid way to measure healthiness. Then briefly describe a measurement process that you think is valid.
14. Rates versus counts. Thirty students in my Stat 1350 class last semester took Test 1 and 25 of them passed the test. Fifty-five students in my Stat 1350 WEB class last semester took Test 1 and 43 of them passed the test.
(a) More students in my WEB Stat 1350 class passed Test 1 than in my traditional Stat 1350 class. Why does this NOT show that my WEB students did better than my traditional students?
(b) What is the passing rate (percentage of students who passed) for each of my Stat 1350 classes?
WEB: __________________________________​​Traditional: ______________________________
15. Obesity. An article in the June 30, 2010, Columbus Dispatch reported on the prevalence of obesity among adults in the 50 states. Based on information in the article, California has approximately 6.7 million obese adults, and Texas has approximately 5.2 million. On the other hand, Mississippi has a little over 730,000 obese adults. Do these numbers make a convincing case that California and Texas have a more substantial problem with obesity than Mississippi?
16. Measuring intelligence. “Intelligence” means something like “general problem-solving ability.” Explain why it is not valid to measure intelligence by a test that asks questions such as
Who wrote “The Star-Spangled Banner”? ______________________________________________________
Who won the last soccer World Cup? __________________________________________________________
17. Testing job applicants. The law requires that tests given to job applicants must be shown to be directly job related. The Department of Labor believes that an employment test called the General Aptitude Test Battery (GATB) is valid for a broad range of jobs. As in the case of the SAT, blacks and Hispanics get lower average scores on the GATB than do whites. Describe briefly what must be done to establish that the GATB has predictive validity as a measure of future performance on the job.
18. Validity, bias, reliability. This winter I went to a local pharmacy to have my blood pressure measured using a sophisticated electronic machine at the front of the store next to the checkout counter. Will the measurement of my blood pressure be biased? Reliable? Valid? Explain your answer.
19. More on bias and reliability. You cut 5 pieces of string having these lengths in inches:
2.9 9.5 5.7 4.2 7.6
A subject measures each length by eye. Make up a set of results from this activity that matches each of the descriptions below. For simplicity, assume that bias means the same fixed error every time rather than an “on the average” error in many measurements.
(a) The subject has a bias of 0.5 inch too long and is perfectly reliable.
​___________​___________​___________​___________ ___________​
(b) The subject has no bias but is not perfectly reliable, so that the average difference in repeated measurements is 0.5 inch.
​___________​___________​___________​___________ ___________​
(c) A subject measures the first length (true length = 2.9 inches) four times by eye. His measurements are
3.0 2.9 3.1 3.0
What are the four random errors for his measurements?
​___________​___________​___________​___________
20. The best earphones. You are writing an article for a consumer magazine based on a survey of the magazine’s readers that asked about satisfaction with mid-priced earphones for the iPod and iPhone. Of 1648 readers who reported owning the Apple in-ear headphone with remote and mic, 347 gave it an outstanding rating. Only 69 outstanding ratings were given by the 134 readers who owned Klipsch Image S4i earphones with microphone. Describe an appropriate variable, which can be computed from these counts, to measure high satisfaction with a make of earphone. Compute the values of this variable for the Apple and Klipsch earphones. Which brand has the better high-satisfaction rating?
21. Measuring pulse rate. You want to measure your resting pulse rate. You might count the number of beats in 5 seconds and multiply by 12 to get beats per minute. Why is this method less reliable than actually measuring the number of beats in a minute?
22. Measuring crime. Twice each year, the National Crime Victimization Survey asks a random sample of about 40,000 households whether they have been victims of crime and, if so, the details. In all, nearly 135,000 people answer these questions per year. If other people in a household are in the room while one person is answering questions, the measurement of, for example, rape and other sexual assaults could be seriously biased. Why? Would the presence of other people lead to over-reporting or underreporting of sexual assaults?
Lesson 3 – Making Sense of Numbers
23.

A survey in a local newspaper stated that of the individuals who frequent bookstores, 14% were male and 28% were female. What is wrong with this picture?


A. Only 42% of the people were surveyed.
B. The percentages only add up to 42%. It should be 100%.
C. There were twice as many females surveyed as males.
D. 58% do not go to bookstores.
E. Nothing is wrong with this picture.

24.

A newspaper reported "Approximately 17% of all crime takes place in the months of August and September." What is misleading about this statistic?


A. August and September are low points for crime statistically.
B. It does not discuss the other months.
C. August and September make up 1/6 of the year which is 17%.
D. None of the choices are correct.

25.

Mark has two coupons—one for 10% off and one for $5 off. The store is allowing him to use both. He says to the cashier to apply the coupons in any order she wants because in the end it's the same amount off. Is he correct? (Hint: Try doing this for an item that is $100.)


A. Yes, it doesn't matter the way the coupons are applied.
B. No, you should apply the 10% off coupon first then apply the $5 off coupon.
C. No, you should apply the $5 off coupon then apply the 10% off coupon.
D. You cannot determine from the information given.

26.

When finding the percent change, your denominator should be:


A. Amount of change
B. Starting value
C. The smaller value
D. The larger value.

27.

If an amount increases from 10 to 40 then the percent increase is:


A. 300%
B. 400%
C. 40%
D. 10%

28.

A newspaper reports "The percent decrease in the amount of wolves is 150%." What does this mean?


A. The amount of wolves has decreased in half.
B. There is 1/3 the amount of wolves that there has been previously.
C. This is not possible. "Percent decrease" can't be more than 100%.
D. None of the choices are correct.

29.

What percentage of 30 is 40?


A. 133%
B. 75%
C. 13.3%
D. 7.5%

30.

The percent increase from 40 to 70 is:


A. 125%
B. 75%
C. 175%
D. 25%

31.

In determining if the numbers make sense you should:


A. Look at the context of the numbers and determine if there is missing information.
B. Look for numbers that don't agree as they should.
C. Compare numbers and look for numbers that are surprisingly large or small.
D. All of the choices are correct.
E. None of the choices are correct.

32. Deer in the suburbs. Westchester County is a suburban area covering 433 square miles immediately north of New York City. A garden magazine claimed that the county is home to 800,000 deer. Do a calculation that shows this claim to be implausible.
33. Trash at sea? A report on the problem of vacation cruise ships polluting the sea by dumping garbage overboard said:
On a seven-day cruise, a medium-size ship (about 1,000 passengers and 1.000 crew members) might accumulate 222,000 coffee cups, 72,000 soda cans, 40,000 beer cans and bottles, and 11,000 wine bottles.
Are these numbers plausible? Do some arithmetic to back up your conclusion. Suppose, for example, that the crew is as large as the passenger list. How many cups of coffee must each person drink every day?
34. Airport delays. An article in a midwestern newspaper about flight delays at major airports said:
According to a Gannett News Service study of U.S. airlines’ performance during the past five months, Chicago’s O’Hare Field scheduled 114,370 flights. Nearly 10 percent, 1,136, were canceled.
Check the newspaper’s arithmetic. What percent of scheduled flights from O’Hare were actually canceled?
35. Battered women? A letter to the editor of the New York Times complained about a Times editorial that said “an American woman is beaten by her husband or boyfriend every 15 seconds.” The writer of the letter claimed that “at that rate, 21 million women would be beaten by their husbands or boyfriends every year. That is simply not the case.” He cited the National Crime Victimization Survey, which estimated 56,000 cases of violence against women by their husbands and 198,000 by boyfriends or former boyfriends. The survey showed 2.2 million assaults against women in all, most by strangers or someone the woman knew who was not her past or present husband or boyfriend.
(a) First do the arithmetic. Every 15 seconds is 4 per minute. At that rate, how many beatings would take place in an hour? In a day? In a year? Is the letter writer’s arithmetic correct?
(b) Is the letter writer correct to claim that the Times overstated the number of cases of domestic violence against women?
36. Stocks go down. On September 29, 2008, the Dow Jones Industrial Average dropped 778 points from its opening level of 11,143. This was the biggest one-day decline ever. By what percentage did the Dow drop that day? On October 28, 1929, the Dow Jones Industrial Average dropped 38 points from its opening level of 299. By what percentage did the Dow drop that day? This was the second-biggest one-day percentage drop ever.
37. Too good to be true? The late English psychologist Cyril Burt was known for his studies of the IQ scores of identical twins who were raised apart. The high correlation between the IQs of separated twins in Burt’s studies pointed to heredity as a major factor in IQ. (“Correlation” measures how closely two variables are connected. We will meet correlation in Chapter 14.) Burt wrote several accounts of his work, adding more pairs of twins over time. Here are his reported correlations as he published them:
