Best Answer

There is no general definition of an outlier. They are normally defined as observations which are more extreme than some multiple of the inter-quartile range beyond the upper or lower quartile. However, the choice of the multiple is arbitrary - a value chosen by the user. I suggest that there are no outliers in the dataset shown.

) Use the non-machine formula to calculate the variance and standard deviation from the following data Herd 1 67 62 69 72 68 68 71 69 65 71 70 64 64 66 71 67 75

6, 16, 26, 36, 46, 56, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69,76, 86, 96

step 1. arrange the numbers in ascending order (from low to high) as follows. was: 64 80 64 70 76 79 67 72 65 73 68 65 67 65 70 62 67 68 65 64 now: 62 64 64 64 65 65 65 65 67 67 67 68 68 70 70 72 73 76 79 80 step 2. count the number of the numbers above, or assign an index as follows. string: 62 64 64 64 65 65 65 65 67 67 67 68 68 70 70 72 73 76 79 80 index: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 so the count is 20. The mode is the number most frequently observed. The mode is 65, which occurs four times. The median is the number in the middle. In this case, the 10th and 11th numbers both qualify for consideration. We take the average of the two numbers. The median is therefore 67. Alternate methods: 1) Use Microsoft Excel statistical functions of =mode() and =median() 2) Draw a bar graph with the horizontal axis of integers from 62 to 80. The y-axis is the frequency observed for that specific x value. For example, the frequency for 62 is one. The frequency for 63 is zero, and so on. The mode is the bar with the highest count. The median is not so obvious from a bar graph, unless the distribution is symmetric. Need some manual counting.

All are composite except 61 and 67. Composite numbers: 60, 62, 63, 64, 65, 66, 68, 69, 70

65 is the median,

Yes. 67's do have some other panels that are unique to that year, but the hoods interchange with older. Starting in 68 the hoods changed.

) Use the non-machine formula to calculate the variance and standard deviation from the following data Herd 1 67 62 69 72 68 68 71 69 65 71 70 64 64 66 71 67 75

(s + 65 + 62 + 70 + 68) / 5 = 66.2 ∴ s + 65 + 62 + 70 + 68 = 331 ∴ s = 331 - 65 - 62 - 70 - 68 ∴ s = 66
