Chapter 1: Q. 88 (page 59)

An advertisement for Acme Investments displays the two graphs in Figure 1.14to show the value of Acme鈥檚 product in comparison with the Other Guy鈥檚 product. Describe the potentially misleading visual effect of these comparison graphs. How can this be corrected?

Short Answer

Expert verified

The potentially misleading visual effect of these comparison graphs is the scales of the x-axis and y-axis may be totally different.

Step by step solution

01

Definition 

The following can be the potential misleading visual effects while comparing the graph:

  • The scales of the x-axis and y-axis may be totally different or both graphs.
  • The numbering of the scale may be different for the graphs.
  • The units on the axis may differ for both graphs.
02

Explanation

Since the graph did not have the marked vertical and horizontal axis, it cannot be measured properly. This can be corrected by assigning the properly marked axis for the vertical and horizontal axis.

Use the following information to answer the next seven exercises: Studies are often done by pharmaceutical companies to determine the effectiveness of a treatment program. Suppose that a new AIDS antibody drug is currently under study. It is given to patients once the AIDS symptoms have revealed themselves. Of interest is the average (mean) length of time in months patients live once starting the treatment. Two researchers each follow a different set of 40 AIDS patients from the start of treatment until their deaths. The following data (in months) are collected.

Researcher A: 3; 4; 11; 15; 16; 17; 22; 44; 37; 16; 14; 24; 25; 15; 26; 27; 33; 29; 35; 44; 13; 21; 22; 10; 12; 8; 40; 32; 26; 27; 31; 34; 29; 17; 8; 24; 18; 47; 33; 34

Researcher B: 3; 14; 11; 5; 16; 17; 28; 41; 31; 18; 14; 14; 26; 25; 21; 22; 31; 2; 35; 44; 23; 21; 21; 16; 12; 18; 41; 22; 16; 25; 33; 34; 29; 13; 18; 24; 23; 42; 33; 29

Would you expect the data to be identical? Why or why not?

鈥淣umber of times per week鈥� is what type of data?

a. qualitative(categorical); b. quantitative discrete; c. quantitative continuous

A study was done to determine the age, number of times per week, and the duration (amount of time) of residents using a local park in San Antonio, Texas. The first house in the neighborhood around the park was selected randomly, and then the resident of every eighth house in the neighborhood around the park was interviewed.

Suggest at least two methods the researchers might use to gather random data.

Describe the unethical behavior, if any, in each example and describe how it could impact the reliability of the resulting data. Explain how the problem should be corrected. A study is commissioned to determine the favorite brand of fruit juice among teens in California.

  1. The survey is commissioned by the seller of a popular brand of apple juice.
  2. There are only two types of juice included in the study: apple juice and cranberry juice.
  3. Researchers allow participants to see the brand of juice as samples are poured for a taste test.
  4. Twenty-five percent of participants prefer Brand X, 33% prefer Brand Y and 42% have no preference between the two brands. Brand X references the study in a commercial saying "Most teens like Brand X as much as or more than Brand Y."
