The second sample consisted of end measurement data (T1) only, since several projects already started before the evaluation started and baseline measurement therefore was impossible.
Some of these variables are highly correlated with each other (such as word form frequency, lemma frequency and familiarity), and their effects can therefore be impossible to estimate independently from each other.
