When a dierent set of users is tested on each prod-uct, there is variation both between

When a dierent set of users is tested on each prod-uct, there is variation both between users and be-tween designs. Any dierence between the meansmust be tested to see whether it is greater thanthe variation between the dierent users. To deter-mine whether there is a signicant dierence betweenmeans of independent samples of users, we use thetwo-sample t-test:

What is multiple linear regression?

Multiple linear regression may be used to nd the re-lationship between a single, continuous outcome vari-able and a set of predictor variables that might becontinuous , dichotomous, or categorical; if categori-cal, the predictors must be recoded into a set of di-chotomous dummy variablesMultiple linear regression, in which two or more in-dependent variables (predictors) are related to a sin-gle dependent variables is much more common thansimple linear regression. Two general principles ap-ply to regression modelling. First, each variable in-cluded in the model should carry its own weight, itshould explain unique variance in the outcome vari-able. Second, when you deal with multiple predictors,you have to expect that some of them will be corre-lated with one another as well as with the dependentvariable.

What do frequentists say about the parent distribution?

Frequentists have a harder time of it ... they say that the parameters of the parent distribution have some fixed albeit unknown values. “It doesn't make sense to talk about the probability of a fixed parameter having some other value---all we can talk about is how likely or unlikely was it that we would observe the data we did given some value of the parameter. Let's try to come up with estimators that are as close as possible to the true value of the parameter.”
