Question 1

In CRO, what does 'statistical significance' indicate in an A/B test?

Accepted Answer

The probability that the observed difference between variants is not due to random chance

Answer

Statistical significance (often expressed as p-value < 0.05 or 95% confidence) tells you the likelihood that the result reflects a true difference rather than random variation.

Question 2

Which of the following is an example of social proof used in ecommerce CRO?

Accepted Answer

Displaying the number of customers currently viewing an item

Answer

Showing real-time viewer counts leverages social proof by signaling demand and popularity, which reduces purchase uncertainty and nudges conversions.

Question 3

What CRO principle does 'Fitts's Law' inform in UI design?

Accepted Answer

Larger and closer targets are easier and faster to click, so CTAs should be prominent

Answer

Fitts's Law states that the time to reach a target is a function of distance and size; CRO applies this by making primary CTAs large and easy to reach.

Question 4

A product page with 47 customer reviews averages 4.1 stars but still has a low add-to-cart rate. Which CRO element should be tested FIRST?

Accepted Answer

Test the product images, description clarity, and CTA button placement

Answer

When trust signals are adequate, low add-to-cart rates typically stem from weak product imagery, unclear value proposition, or a CTA that isn't prominent enough.

Question 5

What is 'anchor pricing' and how does it influence conversion?

Accepted Answer

Displaying a higher original price next to the sale price to make the discounted price feel like a better deal

Answer

Anchor pricing uses a higher reference price (crossed-out MSRP) to make the actual price appear more attractive, leveraging the anchoring cognitive bias to boost conversions.
