Natasha tells her psychology professor that she wants to study why similarity leads to attraction. "That’s great," her professor replies. "But what do you mean, exactly, by ‘similarity’ and ‘attraction’?" What is Natasha’s professor urging her to do?

Create operational definitions of the variables she wants to study

Explanation:

Natasha's professor wants her to create operational definitions of the variable terms in the research that she wants to study. This is evident by the question he asked, ' what do you mean exactly by similarity and attraction'. In research, operational definition means assigning a meaning to the variable of study or interest. She has to define these terms in a way that they are observable and measurable.
