Study Notes
Types of Quantitative Data and Measures
- Measures of individual performance: various forms of tests or personality assessments, where the individual's grade is a measure of how well they did in comparison with a large group of test takers.
- Measures of individual attitude: affective scales that measure positive or negative effects for or against a topic.
- Observation of individual behavior: behavioral checklists used to record observations about individual behavior.
- Factual information: public documents that provide data about a sample or population.
Designing Instruments
- Consider using existing instruments and modifying them to suit your study.
- Random number generators can be used to generate random numbers for sampling purposes.
Systematic Sampling
- Involves choosing every nth individual or site in the population until you reach your desired sample size.
- Use sample fraction to determine the frequency of selection.
- Calculate sample fraction and use random numbers to select the first case.
Reliability and Validity of Instruments
- Reliability: the ability of an instrument to produce stable and consistent scores, regardless of the number of times it is administered.
- Validity: the degree to which all evidence points to the intended interpretation of test scores for the proposed purpose.
- Scores must be reliable before they can be valid or meaningful.
