External validity describes how well the results can be generalized to situations outside of the study.

Here, preoperational means before translating constructs into measures or treatments, and explication means explanation – in other words, you didn’t do a good enough job of defining (operationally) what you mean by the construct.

A variable that's measured on a nominal scale is a _________ variable, If a variable has no true zero, but equal intervals (likert scale), 2 variables are measured; searching for an association, One variable is manipulated, one is measured; searching for causation, Abstract idea that you describe in the operational definition. It studies the construct or psychological attributes that a test measures. Validity pertains to the connection between the purpose of the research and which data the researcher chooses to quantify that purpose. Start studying Construct Validity.

Example: You might look at a measure of math ability, read through the questions, and decide that yep, it seems like this is a good measure of math ability. How is this a threat? Like external validity, construct validity is related to generalizing. But for a many things we want to measure, there is not necessarily a pertinent criterion available. words in the questions reflect what is being measured ex: rose…. Although this is probably the weakest way to try to demonstrate construct validity, we can improve the quality of face validity assessment considerably by making it more systematic. Construct validity is "the degree to which a test measures what it claims, or purports, to be measuring." In other words, can you reasonably draw a causal link between your treatment and the response in an experiment? Construct validity means that the test scores are examined in terms of a construct. Construct validity is a device used almost exclusively in social sciences, psychology and education. For example, a survey researcher who claims constructive validity for a measure of satisfaction will have to demonstrate in a scientific manner that satisfied respondents behave differently from dissatisfied respondents. Published on May 1, 2020 by Pritha Bhandari. For example, think about the driving test as a social measurement that has pretty good predictive validity.
