Explain why researchers cannot claim causation when examining the relationship between variables? -
correct answer ✔✔Researchers cannot claim that one variable causes another because they are not
entirely sure which variable impacts the other when examining the relationship between them.
Researchers also do not know for sure how many unknown or untested variables influence another
variable. Therefore, claiming that one variable causes another would be inaccurate.
A negative correlation between two variables indicates that one variable score increases as another
variable score decreases.
True or false - correct answer ✔✔True
