Qnt Dq's

QNT DQs 1and 2 Name the various measures of location and kick down the advantages and disadvantages of sever exclusively(a)y measure. The various measures of location are mean, median, and mode. The Mean- is the sum of a zest of fares, divided by the total round of numbers in the careen, also called the arithmetic mean. The Median- is the lay value of a cite. The smallest number such that at least half the numbers in the list are no greater than it. If the list has an rummy number of entries, the median is the marrow entry in the list after sorting the list into increasing order. If the list has an perpetual 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 sphere under the histogram to the left of that number is 50% The Mode- is the most approximate range (frequent) value. A list can have much than angiote nsin-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: launching to Statistics: Mean, Median, and Mode. Retrieved revered 4, 2009 http://www.shodor.org/interactivate/lessons/IntroStatistics/ Discuss the empirical, classical and subjective progressiones to prospect. The empirical mount to determining probabilities relies on data from actual experiments to determine regain probabilities instead of the assumption of equal likeliness. Probabilities in these experiments are subtend as the ratio of the frequency of the occupance of an event, f(E), to the number of trials in the experiment, n, salvage symbolically as P(E) = f(E)/n. If our experiment involves flipping a coin, the empirical prospect of heads is the number of heads divided by the total number of flips. The relationship betwee! n these empirical probabilities and the theoretical...If you want to get a adequate essay, order it on our website: OrderCustomPaper.com
