Answer Key

Normal test data
Section A: Quick Questions
Q1
B — 30
Q2
B — Accept it
Q3
A — A typical valid value that should be accepted
Q4
A — 65
Q5
A — False
Section B: Match the Pairs
Q1
Age = 30 (range check 0 to 120) → Normal test data: a typical valid value well inside the limits, so the program should accept it
Q2
Expected outcome: accepted → What should happen when normal test data is entered into the program
Q3
Normal test data is a typical valid value that is well inside the limits and should be accepted → IF Age >= 0 AND Age <= 120 THEN OUTPUT "Accepted" ENDIF // test with 30
Q4
A test case using normal data pairs the input with the expected outcome of accepted → Input: 45, Expected output: Accepted
Q5
Normal test data for an age range of 0 to 120: 150 → 150 is outside the allowed range, so it is abnormal test data, not normal. Normal data must be valid, such as 30.
Q6
Normal test data: 120, Expected outcome: Rejected → Normal data is valid and should be accepted, not rejected. Also 120 is at the limit, so it is boundary data, not well inside the limits.
Section C: Definitions
Q1
Normal test data — A typical, valid value well inside the allowed limits, which the program should accept. Example: an age of 30 for a range check of 0 to 120 is accepted.
Section D: Fill in the Blanks
Q1
IF Age >= 0 AND Age <= 120 THEN
Q2
Age ← 30 // normal test data
Q3
INPUT Age IF Age >= 0 AND Age <= 120 THEN OUTPUT "Accepted"
Q4
DECLARE Age : INTEGER
Q5
IF Age >= 0 AND Age <= 120 THEN
Section E: Spot the Error
Q1
B — 150 is outside the range 0 to 120, so it is abnormal data, not normal data. Normal test data must be a valid value such as 30.
Q2
A — Normal test data is valid, so the program should accept it, not reject it. The line should say 'Normal test data is accepted'.
Q3
B — 50 is a typical valid value inside 1 to 100, so the expected result is accepted. It should read 'Expected result: accepted'.
Q4
C — An age of 30 is normal data and passes the range check, so the THEN branch should output "Accepted".
Q5
C — 30 is a valid value well inside 0 to 120, so it is normal test data. Abnormal data would be invalid, such as -5.
