GRI Data Collection & Measurement Techniques

Question 1

What is the primary goal of data collection in research?

Accepted Answer

Gather accurate & relevant data

Answer

The fundamental purpose of data collection in any research endeavor is to acquire information that is both precise and directly pertinent to the research questions or objectives. Gathering accurate data ensures the reliability and validity of findings, while relevance ensures that the collected information contributes meaningfully to answering the research problem. Without accurate and relevant data, any subsequent analysis or conclusions would be flawed and unreliable.

Question 2

Which method involves direct observation for data collection?

Accepted Answer

Observation

Answer

Observation as a data collection method inherently involves directly watching and recording behaviors, events, or phenomena as they occur in their natural setting. Unlike surveys or interviews which rely on self-reported information, or experiments which manipulate variables, direct observation provides firsthand insights. This method allows researchers to gather non-verbal cues and contextual information that might be missed through other techniques.

Question 3

What is sampling in data collection?

Accepted Answer

Selecting subset of population

Answer

Sampling is a crucial technique in data collection where researchers select a representative portion or subset from a larger population to study. This is done because it is often impractical or impossible to collect data from every single member of an entire population. By carefully selecting a sample, researchers aim to draw conclusions that can be generalized back to the larger population with a reasonable degree of accuracy and confidence.

Question 4

Which tool is commonly used for precise measurement in research?

Accepted Answer

Calipers and micrometers

Answer

Calipers and micrometers are specialized measuring instruments designed for highly precise measurements of small dimensions, such as thickness, diameter, or depth. They offer much greater accuracy and resolution compared to general tools like scales, thermometers, or stopwatches, which measure weight, temperature, and time respectively. Their fine adjustment mechanisms make them indispensable in fields requiring meticulous dimensional analysis.

Question 5

Why is calibration important for measurement instruments?

Accepted Answer

Ensure accurate readings

Answer

Calibration is the process of comparing the readings of a measurement instrument against a known standard to identify and correct any deviations. This process is critical because it ensures that the instrument provides accurate and reliable readings, minimizing measurement errors. Regular calibration maintains the instrument's precision over time, which is essential for valid and trustworthy research data.
