Put them in order, least to greatest.
62, 78, 84, 89, 94, 94, 96, 98
The range is the smallest subtracted from the largest. 98 - 62 = 36
The range is 36.
The median is the average of the middle two. 89 + 94 = 183 divided by 2 = 91.5
The median is 91.5
Range = 89 - 78 = 11
78 + 84 = 162
# Well, the mean is like the average. So if you had these numbers 5,10,and 15, the mean(average) would be 10. # The median is like the middle number in a set of numbers. So if these were your numbers 3, 54, 66,71,75, 76, 78, 84, 88, 92, 99. The median is 76. # The mode is the number that repeated itself more then once. (there can be more than 1 mode) So if these were your set of numbers, 12, 12, 12, 43, 53, 61, 78, 84, 94, 99,99,99,99. Then your mode would be 99. # The range is the difference between the min. and max. numbers in your set of number. So if your set of numbers were 15,34,57,78,81,97. The range would be 82.
For median the list needs to be sorted into increasing order, but doing so also helps with the range and mode, so I'll do that first: {89, 76, 85, 76, 77, 84} → {76, 76, 77, 84, 85, 89} Mean: add them up and divide the sum by how many numbers there are: mean = (89 + 76 + 85 + 76 + 77 + 84) / 6 = 81 1/6 ≈ 81.167 Median: middle number when listed in order; if there are an even number of data items, then the median is the mean average of the middle two: There are 6 data items so median is mean average of middle two: median = (77 + 84) / 2 = 80 ½ = 80.5 Mode: the most frequent, it the number which occurs the most often. There can be more than one mode: mode = 76 as there are two of them and only 1 of all the other numbers. Range: the difference between the greatest and least numbers: range = 89 - 76 = 13
no 78 is 6 less than 84
Median = 94 but that sure was a weird spelling test!
The range is 36 because 98-62=36. Hope this helps :)
Median: 80 Mode: 72, 80, 120, 98, 78, 84, 77
The median is 86.
Range = 89 - 78 = 11
83
It is {58, 62, 66}.
The median is 94.
It is 82
78 + 84 = 162
The median is 84.
the GCF of 84 and 78 is: 6 the common factors of 78 and 84 are: 1,2,3, and 6
