Lesson 4-3 explained: Methods for Evaluating Websites
Quantitative (PV, bounce rate, CVR) shows how much; qualitative (usability tests, interviews, heuristic checks) shows why. Combine both to evaluate a site clearly.
Lesson summary
Quantitative evaluation uses numerical data — through web analytics indicators such as PV (how many views), bounce rate (how many leave after the first page), and CVR (how many reach a target action) — to show how much a site is used.
Takeaway: Quantitative (PV, bounce rate, CVR) shows how much; qualitative (usability tests, interviews, heuristic checks) shows why. Combine both to evaluate a site clearly.

1. Which question does qualitative evaluation answer, and which does quantitative evaluation answer?
- Qualitative: how much? Quantitative: why?
- Qualitative: why? Quantitative: how much?
- Both answer: where?
- Both answer: when?
Answer
Correct answer: Qualitative: why? Quantitative: how much?
Qualitative evaluation looks for the why, from users' voices and behavior; quantitative measures the how much, with numbers.

2. What does the PV indicator mean?
- The number of different people who visited
- The average time a visitor spent on a page
- The total number of times a page was viewed
- The share of visitors who completed a purchase
Answer
Correct answer: The total number of times a page was viewed
PV (page views) is the total number of times a page was viewed, and can include repeat views.

3. A student wrote: "bounce rate = the share who bought or signed up". Is he right?
- True, and it is also called PV
- True; that defines the bounce rate
- False; that describes the conversion rate
- False; that describes heuristic evaluation
Answer
Correct answer: False; that describes the conversion rate
The share reaching a target action is the conversion rate; the bounce rate is about visits ending quickly (e.g. after the first page).
