Exam 3: Practical Measurement Concepts

In general,which of the following measures do teachers use most frequently to interpret scores from class tests?

Which type of validity requires a synthesis of scientific research data about test performance and the domain measured by the test?

Which type of reliability is often preferred by test developers because it is easy to obtain and it produces accurate results?

For which type of reliability is the length of time between testing a critical factor?

Which word is closest in meaning to the term reliability?

Provide the manuals for frequently used tests and have students review the validity and reliability information in the manuals.

What is the name for test scores that follow an even pattern of distribution with about an equal number of scores falling above and below the average score?

If the mean of a distribution is 100 and the standard deviation is 15,what percentage of scores occur between +1 and -1 standard deviations? What percentage of scores occur between +2 and -2 standard deviations?

Provide the manuals for frequently used tests and have students review the norm development information in the manuals.

Which statistic summarizes the variability of groups of scores by measuring the average distance of individual scores from the mean?

Create flash cards using the key terms from the chapter and have students practice learning the terms in small groups.Some of the key chapter terms include norm-referenced and criterion-referenced testing,reliability,and validity.Other important terms include normal distribution,mean,standard deviation,and standard error of measurement.

Which type of reliability compares the direct observations of two observers?

Help students identify some of the most widely used norm-referenced tests.Then have the students review the information about the tests in Mental Measurements Yearbook.
