Reliability

Refers to the level of consistency of an instrument and the degree to which the same results are obtained when the instrument is used repeatedly with the same individuals or group.

• Validity

• Reliability

• Variance

• Stabilization

Tests that are highly reliable are likely to have standard error of measurements that are __________ than in similar tests with low reliability.

• lower

• higer

• the same as

Do you need to increase or decrease the number of questions on a test to increase reliability?

• increase

• decrease

Obtaining similar scores for the same group of people form repeatedly using the same instrument over and over is an indication of the instrument's ________.

• Standar Error of Measurement

• Test Norms

• Reliability

• Validity

This form of reliability is useful when administering a pretest and a posttest.

• Test-Retest Reliability

• Measures of Internal Consitency

• Inter-Rater Reliability

• Alternate Forms Reliability

Used to meausre agreement or intercorrelation among test items.

• Kuder-Richardson Methods

• Corbach's Coefficient Alpha

• Inter-Rater Reliabilty

• Split-Half Method

If the variability of the test scores is higher then the reliabilty is expected to be higher.

• True

• False

Provides information about the variability of a person's scores obtained upon repeated administration of a test.

• Deviance

• Validity

• Reliability

• Standard Error of Measurement
