It is a systematic, objective, and logical process of inquiry based on empirical evidence, involving observation, hypothesis formulation, data collection, and analysis to establish facts and principles.
Population refers to the entire group under study, while a sampling frame is a specific list or source from which the sample is actually drawn, ideally representing the population.
It is a probability sampling technique where every member of the population has an equal and independent chance of being selected, often using random number generators or lottery methods.
Purposive sampling is a non-probability technique where researchers deliberately choose participants based on their specific characteristics, knowledge, or experience relevant to the research topic.
Structured interviews use pre-determined, standardized questions. Unstructured interviews are more flexible and conversational, guided by a general topic but allowing for open-ended responses.
The case study method involves an in-depth, detailed examination of a single individual, group, institution, or event to explore the complexities and uniqueness of a specific phenomenon.
The median is the middle value in an ordered dataset. It is identified by arranging data from lowest to highest and locating the central score, which is less affected by outliers.
In non-participant observation, the researcher observes the subject or group from a distance without actively engaging or participating in their activities.
The mode is most useful for nominal data (e.g., categorizing favorite colors or religious affiliation) to identify the most common category.
A pilot study is a small-scale trial run of the research instrument (like a questionnaire) to identify and fix any ambiguities, errors, or flaws before the main data collection begins.
