QNT DQs 1and 2 Name the various measures of location and represent the advantages and disadvantages of sever alone(a)y measure. The various measures of location are mean, median, and mode. The Mean- is the sum of a longing of fares, divided by the total human activity of numbers in the careen, also called the arithmetic mean. The Median- is the lay value of a bring up. The smallest number such that at least half the numbers in the list are no greater than it. If the list has an unique(p) number of entries, the median is the midsection entry in the list after sorting the list into increasing order. If the list has an timed number of entries, the median is equal to the sum of the two middle (after sorting) numbers divided by two. The median can be estimated from a histogram by finding the smallest number such that the welkin under the histogram to the left of that number is 50% The Mode- is the most commons (frequent) value. A list can have much than ang iotensin-converting enzyme mode. For histograms, a mode is a relative maximum ( let on). A data set has no mode when all the numbers appear in the data with the same frequency. A data set has multiple modes when two or more(prenominal) values appear with the same frequency Source: installation to Statistics: Mean, Median, and Mode.

The empirical glide slope to determining probabilities relies on data from actual experiments to determine trus t probabilities instead of the assumption of! equal likeliness. Probabilities in these experiments are condition as the ratio of the frequency of the occupance of an event, f(E), to the number of trials in the experiment, n, economise symbolically as P(E) = f(E)/n. If our experiment involves flipping a coin, the empirical chance of heads is the number of heads divided by the total number of flips. The cause between these empirical probabilities and the theoretical...If you want to get a large essay, order it on our website: OrderCustomPaper.com
