Question

A cognitive psychologist conducted a study of whether familiarity of words (X) predicts the time it takes (in seconds) to press a button indicating whether the word is singular or plural (Y), with all participants being given the same words. Familiarity with these words was rated at a later time on a 7-point scale (with higher numbers indicating more familiarity). The participants' scores were:

X : 6, 2, 5 ,3 ,7

Y : 0.3 , 1.5 , 0.8 , 1.4 ,0.1
