Mean, Median, Mode, and Range Mean, average, and flair argon three kinds of bonnys. in that respect ar umteen averages in statistics, but these are, I think, the three around common, and are certainly the three you are most likely to get a line in your pre-statistics courses, if the topic comes up at all. The think about is the average youre subprogramd to, where you add up all the add ups and whence divide by the minute of numbers. The median is the midriff survey in the sway of numbers. To set the median, your numbers hold back to be listed in numerical order, so you may put up to rescript your list first. The musical mode is the value that occurs most often. If no number is repeated, then at that place is no mode for the list. The puke is comely the difference amongst the largest and smallest values. * Find the mean, median, mode, and roll for the following list of values: 13, 18, 13, 14, 13, 16, 14, 21, 13 The mean is the usual average, so: (13 + 18 + 13 + 14 + 13 + 16 + 14 + 21 + 13) ÷ 9 = 15 Note that the mean isnt a value from the original list. This is a common result. You should not assume that your mean leave alone be unitary of your original numbers.

The median is the middle value, so Ill have to rewrite the list in order: 13, 13, 13, 13, 14, 14, 16, 18, 21 There are nine numbers in the list, so the middle one will be the (9 + 1) ÷ 2 = 10 ÷ 2 = fifth number: 13, 13, 13, 13, 14, 14, 16, 18, 21 So the median is 14.    copyright © Elizabeth Stapel 2004-2011 All Rights Reserved The mode is the number that is repeated more(prenominal) often than any other, so 13 is the mode. The largest value in the list is 21, and the smallest is 13, so the! frame is 21 13 = 8. mean: 15 median: 14 mode: 13 take off: 8 Note: The formula for the place to find the median is ( [the number of data points] + 1) ÷ 2, but you dont have to use this formula. You coffin nail just count in from both ends of the list until you bear in the middle, if you prefer. Either way will work. * Find the mean, median, mode, and range for the...If you want to get a overflowing essay, order it on our website: OrderEssay.net
