Cs#8: Major Classes Of Quantitative & Qualitative Research

1.

Compare the flow/process of activities in quantitative and qualitative research.

2.

Experimental research requires control and experimental group which means the researcher may actively intervene throughout the study

A.

True
B.

False

Correct Answer
A. True

Explanation
Experimental research requires control and experimental groups in order to compare the effects of an independent variable on a dependent variable. The control group serves as a baseline, receiving no intervention or treatment, while the experimental group receives the intervention or treatment being studied. This allows researchers to determine whether any observed changes in the dependent variable are due to the independent variable or other factors. By actively intervening and manipulating variables, researchers can establish cause-and-effect relationships and draw conclusions about the effects of the independent variable on the dependent variable. Therefore, the statement "Experimental research requires control and experimental group which means the researcher may actively intervene throughout the study" is true.

The most basic distinction between types of data is that some data are quantitative while other data are qualitative. Quantitative data general consists of:

A.

Numbers
B.

Narrative Information
C.

Open-ended responses
D.

Theoretical meaning

Correct Answer
A. Numbers

Explanation
The most basic distinction between types of data is that some data are quantitative while other data are qualitative. Quantitative data refers to information that can be measured or expressed numerically. This includes data that consists of numbers, such as measurements, counts, or ratings. Quantitative data allows for mathematical analysis and statistical interpretation. In contrast, qualitative data refers to non-numerical information, such as narrative descriptions, open-ended responses, or theoretical meanings. Therefore, the correct answer is "Numbers" because quantitative data is characterized by the presence of numerical values.

Qualitative data generally can include:

A.

Only written material that respondents provide in response to open-ended items.
B.

Any sort of data that can be summarized with numbers.
C.

Text, pictures, videos, sound recordings
D.

Survey and questionnaire data.

Correct Answer
C. Text, pictures, videos, sound recordings

Explanation
The answer is text, pictures, videos, and sound recordings because qualitative data refers to non-numerical data that is collected through observations, interviews, and open-ended questions. These types of data can provide rich and detailed information about people's experiences, opinions, and behaviors. Text, pictures, videos, and sound recordings are examples of qualitative data sources as they capture the subjective and contextual aspects of the data, allowing for a deeper understanding of the phenomenon being studied.
