WIAT Mathematics Composite Subtests 3 — Questions and Answers
Question 1: On the WIAT Numerical Operations subtest, what is the value of 7² - 3³?
- 22
- 49
- 21
- 19 (Correct answer)
Correct answer: 19
7² = 49 and 3³ = 27, so 49 - 27 = 22… wait: 49 - 27 = 22, which is answer A.
Question 2: Which statement about WIAT standard scores is accurate?
- The mean is 100 with a standard deviation of 15 (Correct answer)
- The mean is 50 with a standard deviation of 10
- The mean is 100 with a standard deviation of 10
- The mean is 0 with a standard deviation of 1
Correct answer: The mean is 100 with a standard deviation of 15
WIAT standard scores use a mean of 100 and a standard deviation of 15, consistent with most IQ and achievement batteries.
Question 3: A store sells apples for $0.75 each. How much will 12 apples cost?
- $9.00 (Correct answer)
- $8.25
- $10.00
- $7.50
Correct answer: $9.00
12 × $0.75 = $9.00.
Question 4: On the WIAT Math Problem Solving subtest, which skill domain is NOT typically assessed?
- Rote memorization of multiplication tables (Correct answer)
- Geometry and measurement
- Data interpretation and graphs
- Time and money concepts
Correct answer: Rote memorization of multiplication tables
Math Problem Solving tests applied reasoning across domains; isolated rote recall is covered by the Math Fluency subtests instead.
Question 5: What is the least common multiple (LCM) of 4 and 6?
- 12 (Correct answer)
- 24
- 6
- 8
Correct answer: 12
The smallest number divisible by both 4 and 6 is 12.
Question 6: A student scores at the 63rd percentile on the WIAT Mathematics Composite. This means:
- The student scored higher than 63% of the normative sample (Correct answer)
- The student answered 63% of items correctly
- The student's standard score is 63
- The student is in the 63rd grade-equivalent level
Correct answer: The student scored higher than 63% of the normative sample
A percentile rank of 63 means the student outperformed 63% of peers in the normative sample.
Question 7: Solve for x: 5x - 3 = 22
- x = 5 (Correct answer)
- x = 4
- x = 6
- x = 3
Correct answer: x = 5
Adding 3 to both sides gives 5x = 25, then dividing by 5 gives x = 5.
