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.
This quiz covers types of quantitative data, including measures of individual performance, attitude, and behavior, as well as factual information. It also explores different types of tests, instruments, and documents used to collect data.
