Chapter 1 Flashcards
What is a test?
A test is a measurement device or technique used to quantify behavior or aid in the understanding and prediction of behavior.
Are test scores perfect measures of a behavior or characteristic?
Test scores are not perfect measures of a behavior or characteristic. A test measures only a sample of behavior, and error is always associated with a sampling process.
Item
An item is a specific stimulus to which a person responds overtly; this response can be scored or evaluated (for example, classified, graded on a scale, or counted)
Item (in simple terms)
In simple terms, items are the specific questions or problems that make up a test. The problems presented at the beginning of this chapter are examples of test items. The overt response would be to fill in or blacken one of the spaces.
What is the importance of items is psychological and educational tests?
Because psychological and educational tests are made up of items, the data they produce are explicit and hence subject to scientific inquiry.
What is a psychological or educational test?
A psychological test or educational test is a set of items that are designed to measure characteristics of human beings that pertain to behavior.
Overt behavior
Overt behavior is an individual ’ s observable activity.
Covert behavior
Covert behavior takes place within an individual and cannot be directly observed. For example, your feelings and thoughts are types of covert behavior.
How do psychologist deal with the meaning of the scores?
To deal with such problems of interpretation, psychologists make use of scales, which relate raw scores on test items to some defined theoretical or empirical distribution.
Traits & scores
Scores on tests may be related to traits, which are enduring characteristics or tendencies to respond in a certain manner. “ Determination, ” sometimes seen as “ stubbornness, ” is an example of a trait; “ shyness ” is another.
Scores & state
Test scores may also be related to the state, or the specific condition or status, of an individual. A determined individual after many setbacks may, for instance, be in a weakened state and therefore be less inclined than usual to manifest determination.
Ability tests vs Personality tests
Type of Tests
There are Individual tests & group tests as well as ability tests & personality tests.
Individual Tests
Those that can be given to only one person at a time are known as individual tests.
The examiner or test administrator gives the test to only one person at a time, the same way that psychotherapists see only one person at a time.
Group Test
A group test can be administered to more than one person at a time by a single examiner, such as when an instructor gives every-one in the class a test at the same time.
Different types of abitlity
Historically, experts have distinguished among achievement, aptitude, and intelligence as different types of ability.
Achievement
Achievement refers to previous learning. A test that measures or evaluates how many words you can spell correctly is called a spelling achievement test .
