Chapter 1: Q2-23BSC (page 1)

In Exercises 21-28,determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate.

M&MsColours of M&Ms (red, orange, yellow, brown, blue, green) are listed in Data Set 27 鈥淢&M Weights鈥� in Appendix B.

Short Answer

Expert verified

The distinct colors of M&M candies can be categorized under thenominalscale of measurement.

Step by step solution

01

Given information

The data for six different colors of M&M candies are provided.

02

Classification of data according to the level of measurement

Different levels of measurement are defined to classify the values of variables according to their properties, which influence their statistical use.

  • Nominal: The nominal scale being the least refined scale, is used only to define qualitative labels using numerical values. It is an unordered scale. For example, pizza toppings at a restaurant can be recorded as 1 for mushrooms, 2 for pepperoni, 3 for jalapenos, and 4 for olives.
  • Ordinal: The ordinal scale records the ordering of data to identify the magnitude of any variable. For example, ranking of body type as 1 for Extremely Fit, 2 for Moderately Fit, and 3 for Poorly Fit. Here, the exact difference between the values cannot be determined.
  • Interval: The interval scale is used to define numerical variables where the ratio of the values cannot be computed. For example, the credit score of a person ranges from 300 to 850, and you can also subtract the values.
  • Ratio: The ratio scale being the most accurate is used to define all numerical variables that can be tabulated, compared, and analyzed. For example, the heights of students in a class are measured in feet and inches.
03

Identification of the appropriate scale

The colors of M&Mcandies are categorical and contain labels like red, orange, yellow, brown, blue, and green with no real order. Thus, they can be written using thenominallevel of measurement.

Simple Random Sample vs. Random Sample Refer to the definition of simple random sample on page 27 and its accompanying definition of random sample enclosed within parentheses.

Determine whether each of the following is a simple random sample and a random sample.

  1. A statistics class with 36 students is arranged so that there are 6 rows with 6 students in each row, and the rows are numbered from 1 through 6. A die is rolled and a sample consists of all students in the row corresponding to the outcome of the die.

b. For the same class described in part (a), the 36 student names are written on 36 individual index cards. The cards are shuffled and six names are drawn from the top.

c. For the same class described in part (a), the six youngest students are selected.

Determine whether the given source has the potential to create bias in a statistical study.

Arsenic in Rice. Amounts of arsenic in samples of rice grown in Texas were measured by the Food and Drug Administration (FDA).

In Exercises 21-28,determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate.

Body Temperatures: Body temperatures (in degrees Fahrenheit) listed in Data Set 3 鈥淏ody Temperatures鈥� in Appendix B.

Exercises 5鈥�8 refer to the study of an association between which ear is used for cell phone calls and whether the subject is left-handed or right-handed. The study is reported in 鈥淗emispheric Dominance and Cell Phone Use,鈥� by Seidman et al., JAMA Otolaryngology鈥� Head & Neck Surgery, Vol. 139, No. 5. The study began with a survey e-mailed to 5000 people belonging to an otology online group, and 717 surveys were returned. (Otology relates to the ear and hearing.)

Response Rate What percentage of the 5000 surveys were returned? Does that response rate appear to be low? In general, what is a problem with a very low response rate?

Poisson Probability Distribution The random variable x represents the number of phone calls the author receives in a day, and it has a Poisson distribution with a mean of 7.2 calls. What are the possible values of x? Is a value of x = 2.3 possible? Is x a discrete random variable or a continuous random variable?
