What can be used to assess validity?

To evaluate criterion validity, you calculate the correlation between the results of your measurement and the results of the criterion measurement. If there is a high correlation, this gives a good indication that your test is measuring what it intends to measure.

What is an example of validity and reliability in assessment?

For a test to be reliable, it also needs to be valid. For example, if your scale is off by 5 lbs, it reads your weight every day with an excess of 5lbs. The scale is reliable because it consistently reports the same weight every day, but it is not valid because it adds 5lbs to your true weight.

What factors affect validity?

Numerous factors affect the validity of the study. The internal validity is affected by the size of the subject/specimen, type or variability of the subject, attrition of the samples, maturation, time taken for evaluation, history, and instrument or assessment sensitivity.

What is validity vs reliability?

Reliability and validity are both about how well a method measures something: Reliability refers to the consistency of a measure (whether the results can be reproduced under the same conditions). Validity refers to the accuracy of a measure (whether the results really do represent what they are supposed to measure).
