Psychometric Assessment Exam: Level 2 Ability - PsyAsia International Community

Psychometric Assessment Exam: Level 2 Ability

Final Course Exam: PAWL2A

Kindly note that because this is a test of your current competence, you will be given only ONE opportunity to take the assessment at the current time.

If you do not pass, you will need to wait at least 7 days (in order to have sufficient time to revise the course content) and pay a re-sit fee of US$99. We charge this fee, both for admin purposes, and to discourage students from taking the exam before they are ready. If you are confident that you are ready to proceed with the assessment, please feel free to do so, but note the only deadline for doing so is your ticket validity, so you do not need to sit this assessment prematurely.

Thank you for your understanding.

Final advice: Please do not use the back buttons on your browser and please stay inside the current tab. Do not switch back and forth between this tab and another. Tab switches are recorded by the system as they are suggestive of looking for the answers elsewhere – we are assessing your own knowledge and competence right now. We reserve the right to cancel certificates of those who switch tabs more than 2-3 times during the exam and to request that you resit.

The number of attempts remaining is 1

Kindly complete the following for tracking and certification purposes.
Name should be entered exactly as you would like to see it on any certificate.

6 / 30

Which of the following statements would be CORRECT for the following data (check all that apply):
SEMean = 1, Norm Group Mean = 16, Norm Group SD = 2

We are 68% certain that the true population mean lies between 15 and 17

We are 96% certain that the true population mean lies between 14 and 18

We are 96% certain that the true population mean lies between 15 and 17

7 / 30

Match the sampling methods with their correct descriptions:

Norm group members are selected based on demographics

Norm group members are recruited as a result of having easy access, perhaps due to an existing relationship with a company

Each person in the norm group has an equal chance of being selected

Validity

Norms

Error

Consistency

Prediction

9 / 30

A candidate scores a raw score of 17 on a test which has a standard deviation of 2 and mean of 17.
How would you feed this back?

You scored at the th percentile. This means that you did better than per cent of similar others. This score falls within the band.

10 / 30

T-score scales have a mean of:

11 / 30

Match the items on the left with the items on the right:

Most frequently occurring value

The middle value in a set of data

Add up all values and then divide by the number of values

12 / 30

Systematic error during testing refers to:

Factors within the environment

Factors within the respondent

Factors within the test

13 / 30

A candidate scored a Z score of +2.
How would you feedback?

You scored at the th percentile. This means that you did better than per cent of similar others. This score falls within the band.

What does the Utility Equation do?

Helps us understand what aspects of the selection process are important in establishing ROI or gain

It does nothing meaningful

Computes how much the testing process costs us

Thurstone

Binet

Cattell

Spearman

The utility equation is as follows:

(note: Average Test Score relates to that of those selected)

Criterion-related validity + Average Test Score + Standard deviation of incumbent job performance

Criterion-related validity x Average Test Score x Standard deviation of incumbent job performance

Construct-related validity x Average Test Score x Standard deviation of incumbent job performance

Construct-related validity + Average Test Score + Standard deviation of incumbent job performance

A company uses an abstract reasoning test as part of its selection process. Candidates who achieve the pass mark are carried forward to the next stage of the selection process. The pass mark is set at a Z score of +2. If the company tests 100 candidates, how many of them are likely to pass?

A test publisher correlates an ability test score with a rating of job performance and concludes that the finding is significant at the 5% level. What does she mean? Choose all that apply:

The finding definitely happened by chance.

The finding is likely to have happened by chance. The probability of it happening by chance is 95% or more.

The finding definitely did not happen by chance.

The finding is unlikely to have happened by chance. The probability of it happening by chance is 5% or less.

Every significant finding is useful in establishing the validity of the test:
