A systematic investigation that requires data to be collected, analyzed, and interpreted of any social or natural phenomena where results and conclusions are aimed at contributing to generalizable knowledge
Aims to use the acquired knowledge in order to contribute directly to the understanding or resolution of practical issues; often identified when the research contributes to the solution of specific practical problems
A generalized body of laws and theories that explains a phenomenon acquired using the scientific method; can be imperfect or far from the truth since it is based on the various theories currently accepted at the time
Often conducted in new areas of inquiry where it intends to scope out the magnitude of a particular phenomenon, problem, or behavior, to generate new ideas
Provides explanations of an observed phenomenon by answering the 'why' and 'how' questions; attempts to correct the dots by identifying causal factors and outcomes of the phenomenon; and often seeks to explain an aspect of life
Is often used to describe an aspect of life richly. This is related to explanatory research but instead answers the 'who', 'what', 'when', and 'where' questions
A strategic plan of how to go about answering the research questions. It is a plan on how to collect, analyze, and interpret the research data. It touches on all parts of the research and acts as a blueprint
The rationale for the research design and is broader in terms of concepts on which it touches. It justifies one's choice of data collection, analysis method, and procedures
A cluster of beliefs and dictates which for scientists in a particular discipline influence what should be studied, how research should be done, and how results should be interpreted
Both an approach to and a method of understanding the behavioral, emotive, and social meanings of lived experiences of individuals; emphasizes the individual's experiences, beliefs, and perceptions
Allows in-depth investigation of complex issues within a specific context based on a small geographical area or a very limited number of individuals as the subjects of the study
Studies naturally occurring discourse and extract shared meanings from such discourse; text is the object of analysis; it is divided into four (4) themes: discourse as a topic, discourse as a form of action, discourse is rhetorically organized, and language is constructive
Primarily concerned with presenting the stories and experiences voiced by study participants as accurately and comprehensively as possible; most common qualitative data analysis used in social, behavioral, and health sciences
Focuses on narratives (storytelling) as the source of data; research focus shifts from "what actually happened" to "tell me what happened"; relates not just lifespans, but also accounts episodes and interconnections among them
Qualitative research occurs in the field or in a naturalsetting where the phenomenon is happening; the researcher engages with the people directly involved and often acclimate themselves to the views, beliefs, and culture of the community in focus
Researchersactasthekeyinstrument in collecting data for qualitative research; the interactions, direct observations, and subjective analysis of the researcher and participants become part of the research process and collected data
The participant and their subjectiveviews on a particular phenomenon are put into emphasis in a qualitative study; these different perspectives are highlighted when presenting the findings of the study
Qualitative research uses multiplesources of data and analysis; data can be collected using interviews, focus group discussions, observations, document reviews, and audio-visual information
Strengths: Prevents imposing biases, important means to dig down information using open-ended questions, ensures mutual understanding between participant and interviewer; Weaknesses: Tendency to ask leading questions, interviews and analysis can be both time-consuming, subjective, and not generalizable, participants' accounts always mean something, but they cannot always be taken at face value
Strengths: First-hand account of observing, prevents imposition of preconceived ideas and explore unforeseen effects; Weaknesses: Observations and analysis can be time-consuming and are not generalizable, observer's presence may influence participants, observer may misinterpret actions, may be subjective
Strengths: Less expensive than individual interviews, provides a relaxed atmosphere so that people feel free to express their views and strengths, responses can be more spontaneous than in a one-to-one interview; Weaknesses: Findings are not generalizable unless sampling techniques are used to constitute the groups, depends on people's ability to talk in groups; group dynamics may inhibit people
