6.4.3. Validation of results

Try these first

1. 1.

   What is the purpose of validation tests?

   Hint

   Think about the consequences of using wrong data.

2. 2.

   Name one type of validation test.

   Hint

   Recall the methods we discussed in class.

3. 3.

   What is the first step in the validation process?

   • Logical Check
   • Field Visit Check
   • Computational Check

   Hint

   Think about verifying data through direct observation.

4. 4.

   True or False: Logical checks are unnecessary if computational checks are conducted.

   • True
   • False

   Hint

   Consider what each type of check aims to achieve.

5. 5.

   You have collected travel data from a survey indicating a standard household size of '2'. Upon checking, you find a record showing three adults traveling. How would you apply logical checks to clarify this discrepancy, and what steps would you take?

   Hint

   Consider what factors might lead to discrepancies in reported travel.

6. 6.

   You discover that during the computational check, an entry lists a household member's age as '101'. What process would you follow to ensure the data's validity?

   Hint

   Think about how often extreme values should prompt a review.
