According to semantic differential theory,any object can be related along ____ dimensions.

In the Likert method,judges rate how favorable they feel towards the items that might be included on the scale.

Brenda is developing a test to identify children who are likely to become "school refusers" (i.e. ,they refuse to attend school).She has a group of experts review her test to ensure it thoroughly addresses factors known to be related to school refusal.Brenda is assessing ____.

Indexes are typically used to assess behaviors of people,organizations,or processes.

Test makers use ____ to attempt to control factors that are irrelevant to the construct being measured.

Who is using an index?

Brenda is developing a test to identify children who are likely to become "school refusers" (i.e. ,they refuse to attend school).She finds that the test is very accurate in identifying girls,but tends to be far less accurate in identifying boys at risk.This is particularly distressing to Brenda,as children identified as potential school refusers receive more positive attention and additional services from the school.Brenda is concerned about the test's ____.

The ____ of a test is very often studied by having experts review the items in a test to be sure they cover the domain comprehensively.

_______________ can be evaluated by seeing how well the test identifies performance on a future activity.

A researcher is generally better off developing his or her own test than using a standardized test.

Describe the steps involved in creating a Likert scale.

Scaling ____.

The branch of measurement that involves the construction of an instrument that associates qualitative constructs with quantitative metric units is _______________.

A response scale like agree/disagree or support/oppose is a(n)_______________ scale.

A(n)____ is usually developed to measure an abstract concept like an attitude.
