Mean simply means average. To find the average of a set of numbers, simply add them all together and then divide by the amount of numbers you added. 72 + 73 + 74 + 75 + 76 = 370 370 ÷ 5 = 74. The mean of {72, 73, 74, 75, 76} is 74, which is also the median.
71 is the median of those numbers.
Listing the 47 numbers in increasing value, the 23rd, 24th, 25th, and 26th numbers are 73. There are 22 scores higher and 22 scores lower, making 73 the median.
71 72 73 74 75 76 77 78 79
Add up the numbers which comes to 971 Then divide by the number of items in the list (=13) which gives 74.692 So your answer is 74.692
Mean simply means average. To find the average of a set of numbers, simply add them all together and then divide by the amount of numbers you added. 72 + 73 + 74 + 75 + 76 = 370 370 ÷ 5 = 74. The mean of {72, 73, 74, 75, 76} is 74, which is also the median.
74
To answer this question, first rearrange the data values in non-decreasing order, which results in 73 74 75 76 78 78 80. The median is defined as the value in the middle of such an array, in this instance 76.
71 is the median of those numbers.
The variance of 73 72 67 74 78 84 79 71 76 76 79 81 75 80 78 76 78 = 16.8456
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
The numbers are 72, 73, 74, 75 and 76.
66
The median is 84.
Listing the 47 numbers in increasing value, the 23rd, 24th, 25th, and 26th numbers are 73. There are 22 scores higher and 22 scores lower, making 73 the median.
71 72 73 74 75 76 77 78 79
75, which is half way between the two middle numbers.
