... relative. For instance, when a person is asked to assign a number between 1 and 10 to their political position, where 1=left-wing and 10=right-wing, one is using an ordinal scale of measurement. Instead of 1 to 10 we could have used 10 to 100 or any increasing list of 10 numbers. For such data, what ...

... Suggestion: If you see two paths, pick the one that you think is most likely to be correct, and discard the other. 4. A computation or calculator routine will rarely provide a complete response. Even if your calculations are correct, weak communication can cost you points. Be able to write simple se ...

... • When both sample sizes are large we can use the central limit theorem according to which the test statistic below follows the standard normal distribution • When the sample sizes are moderate but normal with equal variances we can use the t-statistic (having n1+n2-2 d.f.) and the pooled variance. ...

... F. Now, consider something weird: Look at the win probabilities for point spreads ranging from 3 to 6. Shouldn’t these be increasing? But they’re not. The problem here is small sample sizes. For example, at the 4.5 mark, you should have n = 35 and at the 5 mark, you should have n =37. But the win pr ...
