Question 1

What are the main steps involved in sample design for market research?

Accepted Answer

Sample design includes six significant steps: identifying the target audience, constructing a sampling frame from relevant data sources, selecting a sampling method, deciding on sample size, collecting data, and validating responses. Each step builds on the previous one to ensure the sample accurately represents the population and supports meaningful research conclusions.

Question 2

Why is creating an accurate sampling frame important in market research?

Accepted Answer

A sampling frame is a detailed, current list of everyone in the target population. An accurate sampling frame prevents missing important segments or including outdated information, ensuring the sample truly represents the entire customer base. This accuracy is essential for drawing valid conclusions and avoiding bias in research findings.

Question 3

How do probability and non-probability sampling methods differ?

Accepted Answer

Probability sampling, like random sampling, gives everyone in the population an equal chance of selection, minimizing bias and ensuring representativeness. Non-probability methods, such as purposive sampling, deliberately focus on specific segments like frequent customers. The choice depends on research design goals and whether generalization to the broader population is needed.

Question 4

What factors determine the appropriate sample size for a study?

Accepted Answer

Sample size depends on the size and variability of the target population and the research design chosen. A larger, more variable population typically requires a bigger sample to draw meaningful conclusions. Researchers balance these factors to ensure the sample is large enough to capture population diversity without unnecessary expense.

Question 5

How does data validation ensure sample quality in market research?

Accepted Answer

Data validation involves checking responses to confirm the sample represents the company's varied customers and reflects population diversity. This process verifies that collected data is accurate and applicable to the broader customer base, supporting informed decision-making and ensuring research findings can be reliably applied beyond the sample.

Question 6

What is the relationship between target population and sampling frame?

Accepted Answer

The target population is the entire group of interest, such as adults who regularly purchase skincare items. The sampling frame is the practical list created from available data sources to represent that population. An accurate sampling frame directly from company databases ensures it reflects the target population, enabling valid sample selection.

Question 7

How does sample design support successful product launch decisions?

Accepted Answer

Sample design enables researchers to gather targeted insights from representative customers through surveys and feedback collection. By validating that the sample reflects customer diversity, researchers can confidently apply findings to broader market decisions. This structured approach transforms customer feedback into actionable intelligence for product launches.
