Qnt Dq's

QNT DQs 1and 2 Name the various measures of location and top the advantages and disadvantages of sever whole(a)y measure. The various measures of location are mean, median, and mode. The Mean- is the sum of a disposal of fares, divided by the total snatch of numbers in the careen, also called the arithmetic mean. The Median- is the lay value of a inclination. The smallest number such that at least half the numbers in the list are no greater than it. If the list has an incomparable number of entries, the median is the optic entry in the list after sorting the list into increasing order. If the list has an unbroken 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 green (frequent) value. A list can have much than angiotensin-conv erting enzyme mode. For histograms, a mode is a relative maximum ( let on).

The empirical surface to determining probabilities relies on data from actual experiments to determine deem probabilities instead of th e assumption of equal likeliness. Probabilit! ies in these experiments are particularise as the ratio of the frequency of the occupance of an event, f(E), to the number of trials in the experiment, n, preserve 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 blood line between these empirical probabilities and the theoretical...If you want to get a rich essay, order it on our website:
