PR2 - PETA2

Question 1

is the framework of research methods and techniques chosen by a researcher to conduct a study. the design allows researchers to sharpen research methods suitable for the subject matter and set up their studies for success

Answer 1

research design

Question 2

it is the individuals or entities who participate and provide data or information in response to the study’s research questions or objectives.

Answer 2

respondents of the study

Question 3

respondents of the study (5)

Answer 3

survey research
psychological research
medical research
market research
educational research

Question 4

a technique of selecting individual members or a subset of the population to make statistical inferences from them and estimate the characteristics of the whole population.

Answer 4

sampling techniques

Question 5

a sampling technique that involves randomly selecting a small group of people (a sample) from a larger population, and then predicting the likelihood that all their responses put together will match those of the overall population

Answer 5

probability

Question 6

a method of selecting units from a population using a subjective (ie, non-random) method

Answer 6

non-probability

Question 7

a tool used to collect, measure, and analyze data related to your research interests. These are commonly used in health sciences, social sciences, and education to assess patients, clients, students, teachers, staff etc.

Answer 7

research instrument

Question 8

types of quantitative research (4)

Answer 8

• DESCRIPTIVE
• CORRELATIONAL
• EXPERIMENTAL
• CAUSAL COMPARATIVE/QUASI-EXPERIMENTAL

Question 9

is a type of quantitative research design that focuses on describing and summarizing data rather than explaining relationships or making predictions.

Answer 9

descriptive research

Question 10

examines the relationships between different subjects and variables without the researcher controlling or manipulating any of them. It is focused on relationships between fixed variables.

Answer 10

correlational research

Question 11

is research that is guided by a specific hypothesis or hypotheses. It is very useful for guiding decision-making.

Answer 11

experimental research

Question 12

used to identify a cause and effect relationship between two variables, where one variable is dependent and another is independent.

Answer 12

causal-comparative/quasi-experimental research

Question 13

2 types of variable

Answer 13

independent variable
dependent variable

Question 14

is information that cannot be counted, measured or easily expressed using numbers. It is collected from text, audio and images and shared through data visualization tools, such as word clouds, timelines, graph databases, concept maps and infographics.

Answer 14

qualitative data

Question 15

2 types of qualitative data

Answer 15

• nominal data
• ordinal data

Question 16

group of objects or ideas that can be collectively grouped on the basis of a particular characteristic
(under qualitative data)

Answer 16

nominal data

Question 17

is a type of data that has a natural ordering or ranking.
(under qualitative data)

Answer 17

ordinal data

Question 18

is information that can be counted or measured or, in other words, quantified—and given a numerical value.

Answer 18

quantitative data

Question 19

2 types of quantitative data

Answer 19

• discrete data
• continuous data

Question 20

refers to numerical values that can only take on specific, distinct values.
(under quantitative data)

Answer 20

discrete data

Question 21

is measured on a continuous scale and can take any value within a certain range. It includes data that can be divided into smaller and smaller units, and there are no gaps or interruptions between the values.
(under quantitative data)

Answer 21

continuous data

Question 22

The validity of a research study refers to how well the results among the study participants represent true findings among similar individuals outside the study.

Answer 22

construction and validation of research instrument

Question 23

In this part of research, the questionnaires given to the participants are retrieved.

Answer 23

administrative and retrieval of the instrument

Question 24

• Taking raw data into something that can be interpreted and used to make decisions.
• Explain all the relevant formulas for the analysis and interpretation of data.
• Verbal interpretations for the computed values may also be summarized in tables.

Answer 24

statistical treatment of data

Question 25

uses various analytical tools to draw inferences about the population using samples.

Answer 25

inferential statistics

Question 26

parts of chapter 2 (7)

Answer 26

• research design
• respondents of the study
• sampling technique
• instrument used
• construction and validation of the instrument
• administration amd retrieval of the instrument
• statistical treatment of data
