median is 79.

Write in order; median is middle number:

{72, 89, 67, 81, 75, 79, 81, 80, 62, 64, 83}

→ {62, 64, 67, 72, 75, 79, 80, 81, 81, 83, 89}

To find middle number, count the number of data items, add 1 and divide by 2.

If this is a whole number, that is the data item which is the median; if it is a fraction, take the mean average of the data items of the positions either side of the fraction (eg if the fraction is 3.5, take the mean average of the 3rd and 4th data items)

There are 11 data items → median is (11+1)/2 = 6th data item

→ median is 79

Q: What is the median of 72 89 67 81 75 79 81 80 62 64 83?

Write your answer...

65 is the median,

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.

It is 68, the number in the middle when they are arranged in order.

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

There are 14 numbers - therefore, the median number is halfway between the seventh and eighth number. This is therefore 70.5.

68 74 93 88 72 89 93 77 62

It is: 69

80

Median is: (54+72)/2 = 63.

49, 36, 25 and 64 are all squares of whole numbers. 64 = 82 49 = 72 36 = 62 25 = 52 The square root of 72 is not a whole number, but approximately 8.48. Thus 72 is the "odd one out".

62 64 66 68 70 72

67 * 72 = 4824.

72

Yes, 72 is greater than 62.

52, 57, 62, 67, 72, 77

Yes 67/72 is in its simplest form

8

The LCM is 2232.

67/72 is in its simplest form.

67/72 is in its simplest form.

72 / 64 = 1 r 8 64 / 8 = 8 r 0 GCF of 72 and 64 is 8.

It is 72/64 = 1.125

47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71.

72 ÷ 62 = 1 with remainder 10

It is: 73
