Chapter 2: Q2.6 (page 40)

Information provided by the World Meteorological Association revealed following data on the highest recorded temperature for each continent.

a. What type of data is presented in the first column of the table ?

b. What type of data is presented in the second column of the table ?

c. What type of data is presented in the third column of the table ?

d. What type of data is provided by the information that Death Valley is in the United States?

Short Answer

Expert verified

1st column : Quantitative Ordinal Variable

2nd column : Qualitative Categorical Variable

3rd column : Qualitative Categorical Variable

Death Valley Location : Qualitative Categorical Variable

4th column : Quantitative Continuous Variable

Step by step solution

01

Basics

  • Quantitative variables can be measured in terms of numerical units.

Ordinal variables are in form of ranks - 1st, 2nd, 3rd & so on

Continuous variable can be in form of whole & non whole numbers - can take values like 4.8, 10.5 etc

  • Qualitative variables can't be measured in terms of numerical units.

Categorical variables can take only few options or categories, like gender 'male' or 'female'

02

Explanation

1st column depicts respective ranks of continents, it is Quantitative Ordinal Variable

2nd column depicts names of continents, it is Qualitative Categorical Variable

3rd column depicts places' names, it is Qualitative Categorical Variable

4th column depicts temperature that can be decimals also, it is Quantitative Continuous Variable

Death Valley location also specifies place category, so it is Qualitative Categorical Variable

Distribution of Wealth In recent years, there has been much discussion about the distribution of wealth of adults in the United States. If you plan to conduct original research by somehow obtaining the amounts of wealth of 3000 randomly selected adults, what graph would be best for illustrating the distribution of wealth?

Cumulative Frequency Distributions. In Exercises 21 and 22, construct the cumulative frequency distribution that corresponds to the frequency distribution in the exercise indicated.

Exercise 5 (Age of Best Actress When Oscar Was Won)

In Exercises 1鈥�6, refer to the data below, which are total home game playing times (hours) for all Major League Baseball teams in a recent year (based on data from Baseball Prospectus).

Histogram Construct the histogram corresponding to the frequency distribution from Exercise 1. For the values on the horizontal axis, use the class midpoint values. Which of the following comes closest to describing the distribution: uniform, normal, skewed left, skewed right?

Frequency Distribution of Body Temperatures Construct a frequency distribution of the 20 body temperatures (oF) listed below. (These data are from Data Set 3 鈥楤ody Temperatures鈥� in Appendix B.) Use a class width of 0.5oF and a starting value of 97.0oF.

97.1 97.2 97.5 97.6 97.6 97.8 98.0 98.0 98.2 98.2 98.2 98.3 98.4 98.6 98.6 98.7 98.7 98.9 99.1 99.4.

Deceptive Graphs. In Exercises 17鈥�20, identify how the graph is deceptive.

Subway Fare In 1986, the New York City subway fare cost \(1, and as of this writing, the current cost is \)2.50, so the 1986 price was multiplied by 2.5. In the accompanying graph, the large bill is 2.5 times as tall and 2.5 times as wide as the smaller bill.
