- an operational definition is not the same as the construct itself; we can define and measure variables(intelligence, motivation, anxiety etc.,)but in fact we are measuring external manifestations that provide an indication of the underlying variables. As a result, there are always concerns about the quality of operational definitions and the measurements they produce. Show The
researchers demonstrated convergent validity by showing strong relationships among the five RQI scale ratings, indicating that the five domains of the RQI are converging on the same construct (relationship quality). - reaction time · Observer error: The individual
who makes the measurements can introduce simple human error into the measurement process, especially when the measurement involves a degree of human judgment. -
height in inches or weight in pounds could be either interval or ratio depending on how the zero point is defined. - constructs often reveal themselves
in overt behaviors that can be observed and measured. The behaviors may be completely natural events such as laughing, playing, eating, sleeping, arguing, or speaking. Or the behaviors may be structured, as when a researcher measures performance on a designated task. In the latter case, a researcher usually develops a specific task in which performance is theoretically dependent on the construct being measured. - a vast number of options, making it possible to select the behaviors that seem to be best for defining and measuring the construct. - The true purpose of a questionnaire can be masked by embedding a few critical questions in a larger set of irrelevant items or by deliberately using questions with low face
validity. Sets with similar termsWhat kind of validity requires that a researcher uses two different measures of the same construct quizlet?- Convergent validity- is demonstrated by a strong relationship between the scores obtained from two (or more) different methods of measuring the same construct.
What are the two common types of validity?There are four main types of validity: Construct validity: Does the test measure the concept that it's intended to measure? Content validity: Is the test fully representative of what it aims to measure? Face validity: Does the content of the test appear to be suitable to its aims?
What are the two types of validity in experimental research?Population validity and ecological validity are two types of external validity. Population validity refers to whether you can generalize the research outcomes to other populations or groups. Ecological validity refers to whether a study's findings can be generalized to additional situations or settings.
What are reliability and validity of a measures?Reliability is about the consistency of a measure, and validity is about the accuracy of a measure. It's important to consider reliability and validity when you are creating your research design, planning your methods, and writing up your results, especially in quantitative research.
