  1. 1A new test of academic achievement amongst GCSE students accurately predicts students’ future A-level marks. This test clearly has which of the following?
    1. APredictive validity
    2. BFace validity
    3. CConcurrent validity
    4. DContent validity
  2. 2Factor analysis is:

    1. AA method for determining the structure of an individual’s personality from a questionnaire.
    2. BA method to determine whether questionnaire respondents have a particular trait.
    3. CA method for determining the underlying structure of a measure.
    4. DA way to prove the consistency of scores on a questionnaire.
  3. 3When evaluating tests and assessments, “reliability” refers to asking ourselves which of the following questions?

    1. ADoes it measure multiple constructs?
    2. BDoes it give consistent results?
    3. CDoes it measure what it is supposed to measure?
    4. DAre there ways to avoid subjective judgments when measuring something?
  4. 4Which of the following is NOT and assumption underlying testing and measurement?

    1. AVarious approaches to measuring aspects of the same thing can be useful
    2. BError is rarely present in the measurement process
    3. CTesting and assessment benefit society
    4. DPresent-day behavior predicts future behavior
  5. 5Which of the following is not a type of reliability?

    1. ATest-retest
    2. BSplit-half
    3. CContent
    4. DInternal consistency
  6. 6Which of the following statements relating to measurements of internal consistency is correct?

    1. ACronbach's alpha is a more sophisticated measure of internal consistency than split-half reliability because it calculates the reliability coefficient based on every possible combination of split-half reliability, thus looking at every possibility.
    2. BSplit-half reliability is a more sophisticated measure of internal consistency than Cronbach's alpha because it allows you to look at two versions of the test at once.
    3. CSplit-half reliability and Cronbach's alpha basically conduct the exact same analysis so you can use either interchangeably and get the same results.
    4. DInternal consistency is not particularly important. Validity (measuring the correct construct) is the most important thing when designing your own measure.
  7. 7Measures of internal consistency are not suitable for which of the following scenarios?

    1. AAll the items in the measure are not measuring the same construct and you have a small number of items
    2. BAll the items in the measure are not measuring the same construct
    3. CAll the items in the measure are measuring the same construct and you have a small number of items
    4. DAll the items in the measure are measuring the same construct
  8. 8When conducting the scale analysis, the section of the output called Cronbach's alpha if item deleted refers to which of the following:

    1. AThe value for Cronbach's alpha that we would need to reach before we decide if the scale is reliable.
    2. BWhat value Cronbach's alpha would be for the whole scale if we removed the specific item on that row.
    3. CWhat value Cronbach's alpha would be for the whole scale if we removed all bad items.
    4. DWhat value Cronbach's alpha would be for the whole scale we had not reverse coded the correct items.
  9. 9Please take a look at the output for a shortened version of a Measure of Confidence- that is it it's development phase.

    Based on the Item-total Correlations for this measure, which item appears to be the least reliable when looking at the relationship with the total score for this measure?    Image for question 9
    1. AQ5_4
    2. BQ5_17
    3. CQ5_6
    4. DQ5_13R
  10. 10Based on the output you used for Question 9 above, what would the overall Cronbach's alpha for the scale be if you removed the least reliable item from the Measure?

    Image for question 10
    1. A.843
    2. B.805
    3. C.827
    4. D.808
