The second hypothesis underlying the cart page experiment was stated as follows: “A transaction
oriented cart page design supported by USPs has a higher cart-to-purchase conversion rate than a
transaction oriented cart page design without USPs.”
On the basis of the experiments result the second hypothesis is rejected (p = 0.139). There was no
statistically significant effect of providing USPs in the cart page design on cart-to-purchase
conversion rates.
Three important aspects influenced the results. First of all the presence of only approximately 900
data points per cart variation made measuring clear differences between the two variations difficult,
given there was a difference in cart-to-purchase conversion rate of only 1%. More data is needed to
clearly measure the effects of providing USPs.
