1. A researcher studied the relationship between familiarity of certain unusual words and the time participant took to indicate whether the word is singular or plural. Participants rated their familiarity of the words (at the end of the experiment) on a 7-point scale (the higher the score, the more familiar with the word). Below are the scores of four participants. 

Person A: familiarity score = 6, reaction time = 1

Person B: familiarity score = 2, reaction time = 3

Person C: familiarity score = 3, reaction time = 2

Person D: familiarity score = 1, reaction time = 6

What’s the correlation between the two variables (Familiarity and Reaction Time)?
