Introduction

A well-designed sampling plan is crucial for ensuring the validity and reliability of research findings. This paper delineates a comprehensive random sampling strategy based on a scenario involving two variables provided by the learning team for the Week 2 Business Research Project Part 1 assignment. The plan specifies the population, sampling methods, sample size calculation, data collection procedures, and protections for human subjects. The goal is to enable another researcher to replicate the method with clarity and precision.

Population and Size

The target population comprises adult consumers aged 18 to 65 who frequent urban shopping centers in a specific metropolitan area. Based on recent census data, the estimated population within this demographic in the area is approximately 500,000 individuals. For practical purposes, the accessible population—those reachable and willing to participate—is estimated at 100,000 individuals, considering factors such as shopping habits, accessibility, and willingness to participate.

Target Population and Reasoning

The target population is chosen to study consumer behavior concerning purchasing preferences and brand loyalty, two variables of interest identified by the team. Focusing on adults aged 18–65 ensures capturing a broad yet relevant demographic that actively engages in shopping activities, making the findings applicable to marketing strategies. This age range also ensures uniformity in data collection and analysis, eliminating confounding variables associated with age extremes.

Sampling Element

The sampling element involves conducting a structured survey administered through data mining techniques at retail locations within the metropolitan area. The survey will comprise 8 questions designed to assess consumer preferences and brand loyalty, including multiple-choice and Likert scale items. The survey questions are as follows:

1. How often do you visit shopping centers? (Weekly, Monthly, Rarely)

2. Which of the following brands do you prefer? (Brand A, Brand B, Brand C, Other)

3. On a scale of 1-5, how loyal are you to your preferred brand?

4. What factors influence your choice of brands? (Price, Quality, Brand reputation, Other)

5. Do you participate in loyalty programs? (Yes/No)

6. How much do you spend on average during a visit? (Under $50, $50–$100, Over $100)

7. Have your shopping habits changed in the last year? (Yes/No)

8. Would you recommend your preferred brands to others? (Definitely, Probably, Not Sure, No)

Alternatively, observation could be employed by researchers noting consumer behaviors at entry points, but given the focus on consumer preferences, survey data collection is selected.

Sample Size

Using a confidence level of 95% and a margin of error of 5%, the required sample size from the accessible population of 100,000 is calculated through the following formula:

\[ n = \frac{Z^2 \times p \times (1-p)}{e^2} \]

Where:

- \( Z = 1.96 \) (for 95% confidence)

- \( p = 0.5 \) (maximizes sample size under uncertainty)

- \( e = 0.05 \) (margin of error)

Plugging in the values:

\[ n = \frac{(1.96)^2 \times 0.5 \times 0.5}{0.05^2} \approx 384 \]

Adjusting for finite population:

\[ n_{adj} = \frac{n}{1 + \left(\frac{n -1}{N}\right)} = \frac{384}{1 + \left(\frac{384 -1}{100,000}\right)} \approx 384 \]

Thus, the sample size remains approximately 384 respondents. The Appendix provides the detailed calculation steps.

Method of Random Sampling

A stratified random sampling method will be employed to ensure representation across key demographic strata such as age groups (18–30, 31–50, 51–65) and income levels. This involves dividing the population into strata based on these variables and randomly sampling within each stratum proportionally. This approach enhances precision and validity.

Data Collection Procedures

Data will be collected through structured surveys administered electronically via tablets at designated retail outlets during peak shopping hours. Training survey administrators ensures consistency in data collection. Participants will be selected randomly within their respective strata using random number generators aligned with customer lists or foot traffic counts. The survey will take approximately 10 minutes per respondent.

Data Storage and Protection

All collected data will be stored securely on encrypted servers compliant with data protection standards. Physical copies, if any, will be kept in locked cabinets accessible only to authorized personnel. Digital data will be backed up regularly, and access will be restricted through password protection and user authentication. Confidentiality agreements will be signed by all personnel involved.

Validity and Reliability

To ensure validity, the survey instrument has been pre-tested for clarity and appropriateness through a pilot study involving 30 participants. Content validity is reinforced by aligning questions with research objectives and relevant literature. Reliability will be maintained through standardized administration procedures and training for data collectors. Internal consistency for Likert scale items will be assessed using Cronbach’s alpha, aiming for a coefficient of 0.7 or higher.

Protection of Human Subjects

Participants will be informed about the purpose of the research, their rights, and confidentiality measures through informed consent forms. Participation is voluntary, and respondents can withdraw at any point without penalty. Data will be anonymized to prevent identification. The research proposal has received approval from an Institutional Review Board (IRB), ensuring compliance with ethical standards.

Conclusion

This detailed sampling plan emphasizes a methodical approach to selecting a representative sample of consumers for the research on shopping preferences. The combination of stratified random sampling, carefully designed survey questions, and stringent data protection measures ensures the collection of high-quality, reliable data. By adhering strictly to this plan, another researcher can replicate the process accurately, thereby contributing to the robustness and credibility of the research outcomes.
