Rejecting the null hypothesis can tell a researcher that a
finding is statistically significant (for example, say there is a
significant difference between students in our class and students
in general) -- but this doesn’t tell us how extreme the difference
really is (just that there is one). What statistical metric tells
us how extreme a result is? (Or, in other words, the extent to
which two population distributions do not overlap)?
A. Effect size / Cohen’s D B. The critical Z score (Zcrit) C.
Statistical Power D. Confidence Intervals
Homework Answers
The answer here is -> Effect size/Cohen's D, since, by definition, the effect size is a quantitative measure by which we can quantify the significant difference between two population distributions. It emphasizes upon the size of this difference alone.

Can we rely on self-evaluations to accurately reflect our own
competence?
To investigate this phenomenon in the lab, Dunning and Kruger
designed some experiments. In one study (Links to an external
site.)Links to an external site., they asked undergraduate students
a series of questions about grammar, logic and jokes, and then
asked each student to estimate his or her score overall, and to
judge their relative rank compared to the other students.
Interestingly, students who scored the lowest in these...

Please read the article and answer about questions. You and the Law Business and law are inseparable. For B-Money, the two predictably merged when he was negotiat- ing a deal for his tracks. At other times, the merger is unpredictable, like when your business faces an unexpected auto accident, product recall, or government regulation change. In either type of situation, when business owners know the law, they can better protect themselves and sometimes even avoid the problems completely. This chapter...
