Chapter 1: Problem 26

In Problems 11-22, identify the type of sampling used. The owner of a private food store is concerned about employee morale. She decides to survey the managers and hourly employees to see if she can learn about work environment and job satisfaction. From the list of workers at the store, obtain a stratified sample of two managers and four hourly emplovees to survey.

Stratified Sampling

Step by step solution

01

Understand Stratified Sampling

Stratified sampling involves dividing a population into distinct subgroups, or strata, that share similar characteristics and then sampling from each of these subgroups.
02

Identify the Subgroups

In this problem, the subgroups are the two types of employees at the food store: managers and hourly employees.
03

Determine the Sample Size for Each Subgroup

The problem specifies that the owner wants to survey two managers and four hourly employees.
04

Obtain the Sample from Each Subgroup

From the list of workers, randomly select two individuals from the manager subgroup and four individuals from the hourly employee subgroup.
05

Verify the Sampling Technique

Ensure that the obtained sample includes individuals from both subgroups as required. This confirms the use of stratified sampling.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

types of sampling
Sampling is a technique used in survey methodology to select a subset of individuals from a larger population. This smaller group, known as a sample, is used to infer information about the entire population. There are several types of sampling methods that researchers can use:
  • Random Sampling: This method involves selecting individuals randomly from the population, ensuring every person has an equal chance of being chosen.
  • Systematic Sampling: Researchers select every nth individual from the population list, using a fixed interval.
  • Stratified Sampling: The population is divided into subgroups (strata) based on shared characteristics and samples are taken from each subgroup.
  • Cluster Sampling: The population is divided into clusters, usually based on geographical areas, and entire clusters are randomly selected.
  • Convenience Sampling: Individuals are chosen based on their convenient accessibility to the researcher.
In our problem, stratified sampling is used because the owner wants to understand differences between two distinct groups of employees: managers and hourly workers. This method ensures representation from both subgroups.
survey methodology
Survey methodology encompasses the processes involved in creating and conducting a survey. This includes designing the survey, selecting the sampling method, collecting data, and analyzing results.

Some key steps in survey methodology include:
  • Defining the Objectives: Clearly determine what you want to learn from the survey.
  • Choosing the Sampling Method: Select the appropriate sampling technique (e.g., stratified sampling) based on your objectives and the population structure.
  • Designing the Survey: Create questions that are clear, concise, and relevant to the objectives.
  • Collecting Data: Administer the survey to the selected sample.
  • Analyzing Results: Use statistical methods to interpret the data and draw conclusions.
In the provided exercise, the objective is to assess employee morale. The owner uses stratified sampling to ensure that both managers and hourly employees are represented, thus providing a clearer understanding of the work environment across different roles.
employee morale
Employee morale refers to the attitudes, satisfaction, and overall outlook of employees within an organization. High morale often leads to increased productivity, better teamwork, and lower turnover rates. Conversely, low morale can result in reduced productivity, poor interaction, and higher employee turnover.

Understanding and improving employee morale involves:
  • Conducting Surveys: Surveys can help gather insights into employee satisfaction and identify areas needing improvement.
  • Open Communication: Encouraging honest and open dialogue between employees and management helps in addressing concerns promptly.
  • Recognition and Rewards: Recognizing and rewarding good performance fosters a positive work environment.
  • Providing Support: Offering resources for professional development, mental health, and work-life balance supports employee well-being.
In the given problem, the store owner is concerned about employee morale and decides to survey both managers and hourly employees. By understanding the morale of both groups, the owner can implement appropriate strategies to enhance the work environment for all employees.

In Problems 11-22, identify the type of sampling used. A pharmaceutical company wants to conduct a survey of 30 individuals who have high cholesterol. The company has obtained a list from doctors throughout the country of 6600 individuals who are known to have high cholesterol. Design a sampling method to obtain the individuals in the sample. Be sure to support your choice.

Suppose a fundraiser holds a raffle for which each person who enters the room receives a ticket numbered 1 to \(N,\) where \(N\) is the number of people at the fundraiser. The first person to arrive receives ticket number 1 , the second person receives ticket number \(2,\) and so on. Determine the level of measurement for each of the following interpretations of the variable ticket number. (a) The winning ticket number. (b) The winning ticket number was announced as \(329 .\) An attendee noted his ticket number was 294 and stated, "I guess I arrived too early." (c) The winning ticket number was announced as \(329 .\) An attendee looked around the room and commented, "It doesn't look like there are 329 people in attendance."

A pharmaceutical company wants to test the effectiveness of an experimental drug meant to reduce high cholesterol. The researcher at the pharmaceutical company has decided to test the effectiveness of the drug through a completely randomized design. She has obtained 20 volunteers with high cholesterol: Ann, John, Michael, Kevin, Marissa, Christina, Eddie, Shannon, Julia, Randy, Sue, Tom, Wanda, Roger, Laurie, Rick, Kim, Joe, Colleen, and Bill. Number the volunteers from 1 to \(20 .\) Use a random-number generator to randomly assign 10 of the volunteers to the experimental group. The remaining volunteers will go into the control group. List the individuals in each group.

Researchers Sally Tracy and associates undertook a cross-sectional study looking at the method of delivery and cost of delivery for first-time "low risk" mothers under three delivery scenarios: (1) Caseload midwifery (2) Standard hospital care (3) Private obstetric care The results of the study revealed that \(58.5 \%\) of all births with midwifery were vaginal deliveries compared with \(48.2 \%\) of standard hospital births and \(30.8 \%\) of private obstetric care. In addition, the costs of delivery from midwifery was \(\$ 3903.78\) compared with \(\$ 5279.23\) for standard hospital care and \(\$ 5413.69\) for private obstetric care.

(b) Name the explanatory variable in the study. (c) Name the two response variables in the study and determine whether each is qualitative or quantitative.
