) 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

I guess you mean: What is the median of the numbers 71, 67, 67, 72, 76, 73, 68, 72, 72? (because adding the numbers would yield a single number). The median is the middle number when the numbers are listed in order. Listing in order: 71, 67, 67, 72, 76, 73, 68, 72, 72 ⇒ 67, 67, 68, 71, 72, 72, 72, 73, 76 There are 9 numbers, so the middle number is the 5th one which is 72. If there had been an even number of numbers, there is no middle one so the median is the mean average of the middle two. Example: If there had been no 76, so the list contained: 67, 67, 68, 71, 72, 72, 72, 73 then there would be 8 numbers, so the median would be the mean average of the 4th and 5th numbers, namely: (71 + 72) ÷ 2 = 71.5

61, 67, 71 = 3

The variance of 80 85 72 76 95 = 79.3

67 * 72 = 4824.

1964 was his first; 67, 71, 72, 74, 75 and 79 are his others.

It is: 5+67 = 72
