If an input field accepts ages from 18 to 60, which of the following is a valid equivalence partition?
easy🧠 Conceptual Q2 of Q15
Step-by-Step Solution
Solution:
Step 1: Identify valid input range
The valid input range is ages 18 to 60 inclusive.Step 2: Match options to valid partitions
Ages 18 to 60 correctly represents the valid equivalence partition. Ages 61 to 100 represents invalid inputs, Ages 0 to 100 is too broad, Only age 18 is a single value, not a partition.Final Answer:
Ages 18 to 60 -> Option BQuick Check:
Valid input range = Equivalence partition [OK]
Quick Trick: Valid inputs form one partition, invalid inputs form others [OK]
Common Mistakes:
MISTAKES- Choosing single values instead of ranges
- Including invalid inputs in valid partitions
- Confusing valid and invalid partitions
