Prof ted is using which comparative method when he studies the frequency of political protests across nations by choosing countries that are very different in most ways except for his key dependent variable (protest outcomes).true / false.

That statement is false

Explanation:

Pay attention to this part of the excerpt:

different in most ways except for his key dependent variable

When a study is conducted through comparative method it will have to compare different countries /cultures and pay attention to all of its features. Professor Ted shouldn't be allowed to exclude out his key depended variables since it could massively influenced the final conclusion of his studies.

is this even a question? ? : /
