The Method of Bootstrapping (5.8)
... Example: Finding the SE(m) using R: Suppose as discussed above that an SRS of size 5 yielded the y-values 4,10,2,8,12, and we would like to estimate SE(m). To do this in R, we could issue the commands below, and consider the following output: There is a command in R called boot that will do this aut ...

... Probability is a branch of mathematics concerned with the concept and measurement of uncertainty. The probability of an event is a number between 0 and 1, inclusive, which represents the likelihood or chance that the event will occur. P(A) denotes the probability of event A. Probability provides a f ...

8a The Variance MEI
... The larger value for set B shows greater variability. Set C has least variability. Can you see a snag with this measurement? ANS: The calculated value increases if we have more data, so comparing data sets with different numbers of items would not be possible. To allow for this, we need to take n, t ...
