A high coefficient alpha indicates thata.scores on the test are stableb.the test has high internal consistencyc.the test has only one factord.the test has high generalizability

Which of the following statements is false? Group of answer choicesWhen factor analysis is used correctly, subtests will be internally consistent (highly reliable) and independent of one anotherIf a scale has a high Cronbach’s alpha, it is necessarily unidimensionalAll of the measures of internal consistency evaluate the extent to which the different items on a test measure the same ability or traitThe closer the value of ∝ to 1, the more confident we can be about the reliability of the test

Cronbach's Alpha is a test for internal consistency reliability for instruments using the Likert scale .

A psychologist is designing a personality assessment questionnaire with 40 items. After administering the questionnaire to a sample of participants, they calculate Cronbach's alpha, which yields a result of 0.90. What does this alpha value suggest?a.The questionnaire has low reliability.b.The questionnaire has a single factor.c.The questionnaire needs more items.d.The questionnaire has high internal consistency.

In his second item analysis, Teacher Vince found out that more from the upper group got the test item #12 correctly. This means that the test item __________.*1 pointa. has a negative discriminating power.b. has a lower validityc. has a positive discriminating powerd. has a high reliability

A Cronbach’s alpha coefficient of 0.80 implies thatGroup of answer choicesthe items of the scale have strong internal consistencythe items of the scale are unidimensionalthe items of the scale have low internal consistencyNeed to do subsequent analysis to make any inference
