Free CRE Data Collection & Analysis Questions and Answers

Question 1

What is the primary purpose of data collection in research?

Accepted Answer

To support or reject hypotheses

Answer

The primary purpose of data collection in research is to gather empirical evidence that can be analyzed to test the study's hypotheses or answer its research questions. By systematically collecting relevant information, researchers can determine whether their initial predictions are supported by the evidence or if they need to be revised. This process is fundamental to advancing knowledge and drawing conclusions.

Question 2

Which method is used to ensure data reliability in research?

Accepted Answer

Ensuring repeatability of results

Answer

Reliability in research refers to the consistency and stability of a measurement or research finding. Ensuring repeatability of results means that if the study were to be conducted again under the same conditions, it would yield similar outcomes. This indicates that the measurement tool or method is dependable and not subject to random error, making the findings trustworthy.

Question 3

What is the difference between qualitative and quantitative data?

Accepted Answer

Qualitative data is descriptive, quantitative data is numerical

Answer

Qualitative data consists of non-numerical information, such as observations, interviews, or text, which describes qualities or characteristics and provides rich, in-depth insights. Quantitative data, on the other hand, is numerical and can be measured, counted, or expressed in statistical terms, focusing on quantities and measurable variables. This distinction is fundamental to research methodology and the types of analysis performed.

Question 4

Which of the following is an example of a primary data source?

Accepted Answer

Answer

Primary data is original data collected directly by the researcher for the specific purpose of their study. Survey responses are a direct collection of information from individuals, making them a prime example of primary data. Published journal articles, library databases, and census data are typically secondary data sources, as they are compiled or published by others.

Question 5

What is the term used to describe data that is collected through observation or interviews?

Accepted Answer

Primary data

Answer

Primary data refers to original information collected directly by the researcher for the specific purpose of their study. Methods like observation and interviews involve direct interaction and firsthand gathering of information from subjects or phenomena. This contrasts with secondary data, which is information already collected by someone else and used for a new purpose.
