Study Notes
Understanding Research Concepts and Methods
- Accessible population is a subset of the target population that researchers can realistically reach and include in a study, based on practical constraints.
- The "researcher as an instrument" concept acknowledges the researcher's role in data collection, particularly in qualitative research where their skills and interactions are crucial.
- Instruments in research refer to tools or methods used for collecting data, such as Likert scales and visual analogue scales.
- Likert scales are used to measure attitudes or opinions, while visual analogue scales assess subjective experiences or perceptions.
- Qualitative data collection methods include field notes, interviews, and observations, capturing detailed narrative descriptions and in-depth information.
- Internal validity refers to the extent to which study effects can be attributed to the independent variable, while external validity concerns the generalizability of findings.
- Threats to internal validity include selection bias, history effects, maturation, testing effects, and instrumentation.
- Threats to external validity include population, ecological, and temporal validity.
- Cronbach's alpha measures internal consistency reliability, commonly used in the social sciences to assess survey instruments or scales.
- KR-20 assesses internal consistency reliability for tests with dichotomous items, providing similar information to Cronbach's alpha.
- Face validity assesses if a measurement appears to measure what it claims to measure, while content validity evaluates if a measurement reflects the entire range of the construct being measured.
- These concepts and methods are fundamental in research and play a crucial role in ensuring the quality and reliability of study findings.
