How do you ensure validity and reliability in research?
How to ensure validity and reliability in your research. The reliability and validity of your results depends on creating a strong research design, choosing appropriate methods and samples, and conducting the research carefully and consistently.
How can a survey be reliable and valid?
Let’s summarize. Validity looks at the extent to which a survey instrument measures what we want to measure. Reliability considers the extent to which the questions used in a survey instrument consistently elicit the same results each time it is asked in the same situation on repeated occasions.
How can researchers check on the reliability of their survey?
Assessing test-retest reliability requires using the measure on a group of people at one time, using it again on the same group of people at a later time, and then looking at test-retest correlation between the two sets of scores. This is typically done by graphing the data in a scatterplot and computing Pearson’s r.
How do you ensure face validity?
Face validity is established when an individual (and or researcher) who is an expert on the research subject reviewing the questionnaire (instrument) concludes that it measures the characteristic or trait of interest.
What is the difference between internal validity and external validity quizlet?
The essential difference between internal and external validity is that internal validity refers to the structure of a study and its variables while external validity relates to how universal the results are.
What refers to external validity quizlet?
External Validity. Refers to the extent to which the results of a research design can be generalized beyond the specific way the original experiment was conducted.
What is external validity quizlet abnormal psychology?
External validity. External validity is the validity of generalized (causal) inferences in scientific research, usually based on experiments as experimental validity. In other words, it is the extent to which the results of a study can be generalized to other situations and to other people.
Which statement accurately differentiates face validity and discriminant validity?
Which statement accurately differentiates face validity and discriminant validity? In face validity, the content of the measure appears to reflect the construct being measured, whereas in discriminant validity, scores on the measure are not related to other measures that are theoretically different.
Which of the following is the most accurate definition of concurrent validity?
Which of the following is the most accurate definition of concurrent validity? It assesses the validity of a test by administering it to people already on the job and then correlating test scores with existing measures of each person’s performance.
Which of the following correlations is the weakest?
The weakest linear relationship is indicated by a correlation coefficient equal to 0. A positive correlation means that if one variable gets bigger, the other variable tends to get bigger. A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.
Which type of validity refers to how theoretically similar two constructs are?
Convergent Validity: measures of theoretically similar constructs should be highly correlated. • degree to which similar concepts that should be related theoretically are interrelated in reality.
When should you use construct validity?
Construct validity is one way to test the validity of a test; it’s used in education, the social sciences, and psychology. It demonstrates that the test is actually measuring the construct it claims it’s measuring.
