PRC Data Collection & Analysis

Question 1

What is the main purpose of data collection in research?

Accepted Answer

To gather evidence for testing hypotheses

Answer

The main purpose of data collection in research is to systematically gather empirical evidence that can be used to test hypotheses or answer research questions. This evidence forms the foundation upon which conclusions are drawn and new knowledge is built. Without robust data, researchers cannot validate their theories or provide credible insights.

Question 2

What is the difference between qualitative and quantitative data collection?

Accepted Answer

Qualitative explores depth, quantitative measures quantity

Answer

Qualitative data collection focuses on gathering non-numerical information to explore depth, meaning, and understanding, often through methods like interviews or observations. In contrast, quantitative data collection involves gathering numerical data that can be measured and statistically analyzed to quantify variables and test hypotheses. The distinction lies in whether the aim is to understand 'why' and 'how' (qualitative) or 'how much' and 'how many' (quantitative).

Question 3

Which data collection method is commonly used in qualitative research?

Accepted Answer

Interviews, focus groups, and observations

Answer

Interviews, focus groups, and observations are primary methods for collecting qualitative data. These techniques allow researchers to gather rich, detailed, and descriptive information about participants' experiences, perspectives, and behaviors in their natural contexts. They are designed to explore complex phenomena in depth, rather than to quantify them.

Question 4

What is the purpose of using a sampling technique in data collection?

Accepted Answer

To select a manageable and representative subset

Answer

Sampling techniques are used to select a smaller, manageable, and representative subset of individuals or items from a larger population. This is crucial because it is often impractical or impossible to collect data from every member of an entire population. A well-chosen sample allows researchers to draw conclusions about the larger population with a reasonable degree of accuracy and efficiency.

Question 5

What is an example of a quantitative data collection method?

Accepted Answer

Surveys with Likert scales or numerical ratings

Answer

Surveys with Likert scales or numerical ratings are a classic example of a quantitative data collection method. These tools generate numerical data that can be easily quantified, aggregated, and subjected to statistical analysis. This allows researchers to measure attitudes, opinions, or behaviors across a large sample and identify patterns or trends.
