Randomly select 3 managers from the list using Simple Random Sampling.

Step by step solution

01

Identify Total Managers

Identify the total number of managers available for the selection process. In this case, the list provides 20 managers who belong to minority groups.
02

Assign Numbers to Managers

Assign a unique number to each manager for easy reference. For instance, assign number 1 to Adelaja, number 2 to Ahmadiani, and so on till number 20 to Yajima.
03

Use Random Sampling Tool

Utilize a Simple Random Sample applet, other software, or a provided random number table (e.g., Table B at line 127) to randomly select three numbers between 1 and 20. Ensure there's no repetition in selection.
04

Match Random Numbers to Managers

Match the randomly selected numbers from the previous step to the corresponding managers based on the numbering assigned in Step 2.
05

Confirm Selected Managers

List the names of the managers corresponding to the randomly selected numbers. These are the ones who will be interviewed about the performance appraisal system.

Key Concepts

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

Management Performance Appraisal
Performance appraisals are vital in organizations as they track how well managers and other employees are performing. They serve to assess strengths and areas of improvement. Furthermore, they foster personal development and can guide management decisions.
These appraisals are critical not just for daily operations, but also for forming strategic plans for advancement. They align individual goals with organizational objectives.
  • Evaluate leadership capabilities
  • Identify training needs
  • Facilitate decisions on promotions
For managers, especially those from minority groups, performance appraisals offer transparency and accountability. They help ensure that all evaluations are fair and unbiased. This kind of equitable evaluation supports diversity and inclusiveness.
Random Number Table
A random number table is a tool used to ensure fair and unbiased selection in sampling methods. It’s a collection of numbers generated without deliberate patterns or repetitions. These numbers are typically used in sampling applications, such as selecting participants for an interview or survey.
Using a random number table is straightforward: Assign each potential subject a number, then refer to the table to select your sample. It ensures every participant or manager has an equal chance of selection.
  • Offers a systematic approach to randomize selections.
  • Can replace more complex software or algorithms.
  • Minimizes selection bias effectively.
For example, in management performance appraisal interviews, selecting managers randomly ensures all groups are fairly represented, thus keeping the appraisal process impartial.
Minority Groups
Minority groups in an organization represent employees who might fall into diverse categories such as race, ethnicity, or gender. Ensuring these groups are part of management appraisals demonstrates inclusivity and equality in organizational practices.
Recognizing the contributions and perspectives of minority groups enriches an organization; it often leads to more innovative solutions and a unified workplace culture.
  • Promotes a sense of belonging among team members.
  • Valuable for understanding diverse client needs and expanding market reach.
  • Helps to reduce any potential unconscious bias in management improvements.
Incorporating minority group members into processes, like performance interviews, supports a holistic view of organizational success and fairness.
Interview Selection Process
The interview selection process systematically determines which individuals out of a group will participate in detailed discussions or evaluations. It is crucial for obtaining diverse insights and perspectives, especially in assessing management performance.
An effective selection process includes planning criteria for selection, using randomization to eliminate bias, and ensuring representation from all relevant groups.
  • Establishes clear criteria and objectives for selection.
  • Ensures fairness and equity through random selection techniques.
  • Contributes to a diverse range of opinions and feedback.
In the scenario of appraising management performance, choosing managers through a random, unbiased selection process allows for a comprehensive review that reflects the organization’s goals of inclusivity and effectiveness.

Most popular questions from this chapter

Seat belt use. A study in El Paso, Texas, looked at seat belt use by drivers. Drivers were observed at randomly chosen convenience stores. After they left their cars, they were invited to answer questions that included questions about seat belt use. In all, \(75 \%\) said they always used seat belts, yet only \(61.5 \%\) were wearing seat belts when they pulled into the store parking lots. 28 Explain the reason for the bias observed in responses to the survey. Do you expect bias in the same direction in most surveys about seat belt use?

How Accurate Is the Poll? A Pew Research Center survey on Teens, Social Media \& Technology at the beginning of 2015 included 1060 teens, of which 614 were white, non-Hispanic; 101 were black, non-Hispanic; 236 were Hispanic; and 109 were other races or ethnic groups. Each teen sampled was asked about technology usage, including access to mobile devices, social media usage, and video game playing. The margin of error (we will give more detail in later chapters) was reported as \(63.7 \%\) for the entire sample. When considering technology usage of only the Hispanic teens, the margin of error was reported as \(68.1 \% .4\) What do you think explains the fact that estimates for Hispanic teens were less precise than for the entire sample?

Running red lights. The sample described in the previous exercise produced a list of 5024 licensed drivers. The investigators then chose an SRS of 880 of these drivers to answer questions about their driving habits. (a) How would you assign labels to the 5024 drivers? Choose the first five drivers in the sample. If you use Table \(\mathbf{B}\), start at line 119 . (b) One question asked was, "Recalling the last ten traffic lights you drove through, how many of them were red when you entered the intersections?" Of the 880 respondents, 171 admitted that at least one light had been red. A practical problem with this survey is that people may not give truthful answers. What is the likely direction of the bias: do you think more or fewer than 171 of the 880 respondents really ran a red light? Why?

Ring-no-answer. A common form of nonresponse in telephone surveys is "ring-no- answer." That is, a call is made to an active number but no one answers. The Italian National Statistical Institute looked at nonresponse to a govemment survey of households in Italy during the periods January 1 to Easter and July 1 to August 31 . All calls were made between 7 and 10 p.m., but \(21.4 \%\) gave "ring-no-answer" in one period versus \(41.5 \%\) "ring-no-answer" in the other period. \({ }^{29}\) Which period do you think had the higher rate of no answers? Why? Explain why a high rate of nonresponse makes sample results less reliable.

Retweeters. Twitter and Compete, a marketing services company, conducted a survey to investigate some of the characteristics of those who retweet (reposting of someone else's tweet). Among other findings, it was found that Twitter users who retweet are demographically similar to those who don't, use Twitter more often during the day, and are more likely to use Twitter on a mobile phone. Here is the methodology section contained with the survey results: The findings are based on data from surveys fielded in the Lnited States during 2D12. Twitter and Compete worked together to build a questionnaire that asked respondents about their propersity to use Twitter and other services as well as the when, where, how and why of their usage patterns. Compete iaterviewed 655 Internet users in the U.S. for this study. 30 (a) Explain in simple language why it is important to know how the sample was selected when drawing conclusions about a survey. (b) Do you feel the methodology section adequately explains how this sample was selected? Explain why or why not. If not, what information is lacking. and why is it important?
