When the results of a particular method of measurement are considered reliable they are quizlet?

The measure of validity based on an evaluation of subjects, the topics, or the content covered by the items in the test Show Involves the logical examination and evaluation of the content of a test (including the test questions, format, wording, and processes required to test takers) to determine the extent to which the content is representative of the concepts that the test is designed to measure describes a judgement of how adequately a test sample's behavior is representative of the universe of behaviors that the test was designed to sample 1. It measures extent to which items on a test are representative of the attribute or construct the test claims to measure (representative of construct) Researchers by using content validity attempt to include relevant factors excluding irrelevant factors 2. Built during and after test development During test you define test universe & identify relevant content areas, matching items with those identified areas. After development of test you can gather Subject Matter Experts (SMEs) to judge the content validity of your test, and then use the content validity ratio (CVR), which quantifies the degree of content validity Content Validity is dependent of human judgement, diff ppl might make diff judgements, so the extent to which a test is seen as content valid for its purpose, really depends on the group you're working with (their background, culture, etc.), even when use experts content validity depends on group of experts you select, or on your own expertise in the area.

Terms in this set (19)Why must measures be reliable? What is the main consequence of using an unreliable measure in a study? Measures must be able to measure the same thing and give consistent data. If a test is unreliable, then the researcher's can't trust the data received. What is measurement error, and what are some things that cause it? -the participant's observed score is the result of factors that distort the observed so that it isn't precisely what it should be Why is it virtually impossible to eliminate all measurement error from the measure we use in research? Because we're human and things are constantly changing and reacting What is the relationship between the reliability of a measure and the degree of measurement error it contains? -reliability of a measure is an inverse function of measurement error What does the reliability of a measure indicate if it is .60? .00? 1.00? -60% of the
total variance in scores is systematic or true-score variance What does a correlation coefficient tell us? Why are correlation coefficients useful when assessing reliability? -a statistic that expresses the strength of the relationship
between two measures on a scale from .00 to 1.00 What are three ways in which researchers assess the reliability of their measures? -test-retest reliability When would you calculate Cronbach's alpha coefficient? What does it tell you? -to measure interitem reliability What is the minimum reliability coefficient that researchers consider acceptable? Why do researchers use this minimum criterion for reliability?
-.70 For what kind of measure is it appropriate to examine test-retest reliability? interitem reliability? interrater reliability? -if the attribute being measured would not be expected to change between two measurements (intelligence, attitudes, or personality) Why are researchers sometimes not able to test the reliability of their measures? -b/c the scale could be self-report What steps can be taken to increase the reliability of measuring techniques? -standardize administration of the
measure What is validity? -the extent to which a measurement procedure actually measures what it is intended to measure rather than measuring something else or nothing at all Distinguish among face validity, construct validity, and criterion-related validity. In general, which kind of validity is lease important to researcher? -extent to which a measure appears to measure what it's supposed to measure (done by professionals) Can a measurement procedure be valid but not reliable? Reliable but not valid? Explain. -it can be reliable but not valid because all the test questions can relate to each other but not actually be a test of what you need to find Distinguish between construct and criterion-related validity. -convergent and discriminant validity Distinguish between concurrent and predictive validity -main difference between them involves the amount of time that elapses b/w administering the measure to be validated and the measure of the
behavioral criterion How can we tell whether a particular measure is biased against a particular group? -examine the predictive validity of a measurement How do researchers identify biased test items on tests of intelligence or ability? -they take those who scored the same and make them all take a single part of the test. If a group (race, gender, age) didn't do well as a whole or all missed a question, then the test item is biased.

If the same result can be consistently achieved by using the same methods under the same circumstances, the measurement is considered reliable.
When a measure is highly reliable quizlet?A measure is said to have a high reliability if it produces consistent results under consistent conditions.
What is meant by the reliability of a measure quizlet?Reliability Definition: The extent to which measurement is CONSISTENT and free from error.
When a measurement has reliability It means that it yields quizlet?A measure is reliable when it yields consistent scores or observations of a given phenomenon on different occasions. Reliability is a prerequisite for measurement validity. Measure obtains same results at 2 different times.
