Study Notes
Research Instruments
- Demographic forms are used to collect information about participants' characteristics, such as age, gender, and occupation.
- Ability tests are used to assess or rate an individual's ability.
Evaluating Research Instruments
- Research instruments are evaluated based on criteria such as reliability, validity, and practicality.
- Internal consistency refers to the extent to which different items in an instrument measure the same concept.
Types of Validity
- Face validity refers to whether an instrument appears to measure what it is supposed to measure on the surface.
- Construct validity includes important characteristics that the instrument is intended to measure.
- Concurrent validity correlates two research instruments taken at the same time.
- Predictive validity refers to the ability of an instrument to predict a criterion.
- Construct validity can be assessed by examining the relationship between the instrument and the underlying theory or concept.
Subtypes of Construct Validity
- Convergent validity involves an instrument that correlates with other similar instruments as expected.
Data Collection
- Quantitative observation involves collecting numerical data through systematic and controlled methods.
- The choice of data collection method depends on the research question, population, and resources.
Data Summary
- Quantitative data summary presents numerical data in a more concise, systematic, and organized manner.
- Visual summary makes use of visual tools such as graphs, charts, and figures to present data.
Data Collection Methods
- Structured interviews involve gathering quantitative research data through the use of standardized questions and structured interview formats.
- Questionnaires with closed-ended questions are used to collect data, where respondents choose from provided answers.
This quiz covers various types of research instruments including demographic forms, performance measures, attitudinal measures, behavioral observation checklists, and factual information documents. It also explores the process of assessing the quality of these instruments.
