Nathan DeWall, David G Myers 955 solutions Myers' Psychology for AP2nd EditionDavid G Myers 901 solutions Score Consists of: 1.) True Score- Intelligence. 2.)Measurement Error- a.) Systematic error- Error happens every time. b.) Random Errors- Error that happen sometimes not every time. 3.) Reliability is the degree to which your measure is free of random error--reliability tests always measure things twice and check for variation 4. Validity refers to the degree to which a study accurately reflects or assesses the specific concept that the researcher is attempting to measure. While reliability is concerned with the accuracy of the actual measuring instrument or procedure, validity is concerned with the study's success at measuring what the researchers set out to measure. 5. Reliability and validity are independent of each other. A measurement maybe valid but not reliable, or reliable but not valid. (eg. Suppose your bathroom-scale was reset to read 10 pound lighter. The weight it reads will be reliable(the same every time you step on it) but will not be valid, since it is not-reading your actual weight.) Recommended textbook solutions

Wilson 525 solutions Can a measure be reliable but not valid can it be valid but unreliable?Reliability and validity are closely related, but they mean different things. A measurement can be reliable without being valid. However, if a measurement is valid, it is usually also reliable.
Can a measure be valid but unreliable quizlet?A measure can be reliable, but not valid. However, a measure cannot be valid unless it is reliable. *Reliability is a necessary but not sufficient condition for validity. For example, you can reliably measure eye color, however, it may not be related to job performance at all.
Why is it possible to have a reliable measure that is not valid?A measure can be reliable but not valid, if it is measuring something very consistently but is consistently measuring the wrong construct. Likewise, a measure can be valid but not reliable if it is measuring the right construct, but not doing so in a consistent manner.
Can a measuring instrument be reliable but not valid provide an example?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. It is not a valid measure of your weight.
