Research Methods Overview

• CBT Revision occurred during Week 9 on Sunday, April 27, from 4:00-6:00pm.

Part 1

• Sampling is the process of selecting a population portion to represent the entire population.

• Quantitative and qualitative are the two main types of research design.

• The null hypothesis states the opposite of what an investigator predicts.

• When undertaking research, the logical sequence is:

  • Formulating a research question
  • Conducting a literature review
  • Collecting data through surveys and interviews
  • Deciding about the data analysis procedure

• Circle graphs show how various parts relate to the whole.

• Research is unethical if it doesn't ensure respondent privacy and anonymity.

• Data collected through the internet is called external secondary data.

• "Formulation of Hypothesis" is followed by the selection of research tools in the research process.

• Focus groups are the exploratory technique used most often in business research.

• Correlation refers to the relationship by which two or more variables covary.

• Snowball sampling involves choosing participants who then refer others with similar or different characteristics, it is a type of nonprobability sampling technique.

• Testing hypotheses is NOT a possible goal of an exploratory study.

• A descriptive study discovers answers to the questions who, what, when, where, or how much.

• An experimental study is one that involves manipulation of one or more variables to determine the effect on another variable.

• Random Sampling is NOT a type of nonprobability sampling technique.

• Purposive sampling involves choosing participants arbitrarily for their unique characteristics, experiences, attitudes, or perceptions.

• Major attribute of correlation analysis is association among variables.

• Identity of respondent is known in the case of a questionnaire is not in fact true.

• To pursue research, formulating a research question is required.

• In research, a bibliography is a list of books and journals referred to.

• A research problem is selected from the standpoint of social relevance.

• A research abstract is a synopsis.

• To study the prospects of a political party in an urban area, a researcher should choose a questionnaire.

• A collection of data is the search for answers to research questions.

• Professional attitude cannot be expressed in quantitative terms.

• Reliability is the extent to which a measurement is accurate and precise.

• Research depth can be judged by research objectives.

• Successful researcher has studied research methodology.

• Test for Reliability and Validity is not a component of data analysis.

• Interpretation in research methodology is the search for research findings.

• Impact factor indicates the quality of a research journal.

• Research is not a process does not correspond to the characteristics of research.

• The aggregate of all units pertaining to a study is called population.

• Formulating a research question is required to pursue research.

• The population to be sampled is divided into sampling units.

• Exploratory studies are loosely structured and designed to expand understanding of a topic and provide insights.

• A statistical study attempts to capture a population's characteristics by making inferences from a sample's characteristics and testing resulting hypotheses.

• An experiment is being conducted when Lulu Shopper uses a catalog of kitchen utensils on the cover is used for one group of consumers and the same catalog with a cover graphic of beddings is used for another consumer group to test differences in response between the two groups.

• Improving job satisfaction is the intervening variable in the statement "The introduction of a four-day week leads to increased productivity particularly among young workers by improving job satisfaction."

• Nonprobability is a sampling technique which involves selecting research participants with no attempt at generating a statistically representative sample.

• A population element refers to the individual participant or object on which a measurement is taken.

• A census occurs when all the elements in a population are included in a study.

• Testing hypotheses is NOT a possible goal of an exploratory study.

• A causal study reveals why or how one variable produces changes in another.

Part 2

• Interviews, surveys, focus groups, and observations are the primary research sources of an exploratory research.
• Online research, literature research, and case study research are the secondary research sources of an exploratory research.
• Descriptive research aims to describe or define the topic at hand, explanatory research aims to explain why particular phenomena work the way they do, and exploratory research is usually conducted when a researcher has just begun an investigation and wishes to understand the topic generally.
• A stratified sample is used when the population is heterogeneous.
• Research design is the conceptual framework in which research is carried out.

Part 3 from Kahoot

• An alternative hypothesis makes a statement that suggests an outcome that an investigation may expect.
• The sequence of activities for research is: Write research questions, Literature Review, Collect data, and Data analysis (ACDB).
