QNT DQs 1and 2 Name the various measures of location and strive the advantages and disadvantages of sever every(a)y measure. The various measures of location are mean, median, and mode. The Mean- is the sum of a temperament of fares, divided by the total fig of numbers in the careen, also called the arithmetic mean. The Median- is the lay value of a make. The smallest number such that at least half the numbers in the list are no greater than it. If the list has an peculiar number of entries, the median is the shopping center entry in the list after sorting the list into increasing order. If the list has an even 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 parking area (frequent) value. A list can have much than angiotens in-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 values appear with the same frequency Source: debut 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 come near to determining probabilities relies on data from actual experiments to determine intend probabilities instead of the assumption of equal likeliness. Probabi! lities in these experiments are pin down as the ratio of the frequency of the occupance of an event, f(E), to the number of trials in the experiment, n, compile symbolically as P(E) = f(E)/n. If our experiment involves flipping a coin, the empirical opportunity of heads is the number of heads divided by the total number of flips. The family between these empirical probabilities and the theoretical...If you want to get a squiffy essay, order it on our website: OrderCustomPaper.com
