Chapter 1: Q. 9 (page 48)

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.

The colors of the houses around the park are what kind of data?

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

Short Answer

Expert verified

The colors of the houses around the park are a qualitative(categorical) type of data, hence, option a is the correct answer.

Step by step solution

01

Concept Introduction

A variable is a type of data and it can be of qualitative, quantitative discrete, or quantitative continuous type based on the given data in statistics.

02

Explanation

A qualitative variable is one that assigns categories to the variable as a value. The variable gender, for example, is a qualitative variable since it assigns male or female categories to the variable gender.

A quantitative discrete variable is one that assigns values that has a definite number of values. Quantitative discrete variables include things like the number of students in a class and the number of days in a month.

A quantitative continuous variable is one that assigns values that have an infinite number of possible values. A quantitative continuous variable is, for example, the weight of students in a class or the distance between two cities.

The colors of the houses around the park can be further categorized and various colors can be assigned as their value, hence, it is a qualitative(categorical) type of data.

03

Final answer

In the given example, the given data type "the colors of the houses around the park" is a qualitative(categorical) type of data.

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 they start the treatment. Two researchers each follow a different set of 40 patients with AIDS 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

Determine what the key terms refer to in the example for Researcher A.

For the following exercises, identify the type of data that would be used to describe a response (quantitative discrete, quantitative continuous, or qualitative), and give an example of the data. . distance to the closest movie theatre

Use the following data to answer the next five exercises: A pair of studies was performed to measure the effectiveness of a new software program designed to help stroke patients regain their problem-solving skills. Patients were asked to use the software program twice a day, once in the morning and once in the evening. The studies observed 200stroke patients recovering over a period of several weeks. The first study collected the data in Table 1.31. The second study collected the data in Table 1.32.

Patients who used the software were also a part of an exercise program whereas patients who did not use the software were not. Does this change the validity of the conclusions from Exercise 1.31?
