The median is the middle value when the numbers are arranged in numerical order. In this case, the middle two numbers are 88 and 92, so the median is (88 + 92) / 2 = 90. The mode is the number that appears most frequently, which is 88 in this dataset. The mean is the average of all the numbers, calculated by adding them up and dividing by the total count. In this case, the mean is (95 + 88 + 79 + 92 + 78 + 88 + 93 + 100 + 69 + 98) / 10 = 88.2.
mean: 60 median: 56.5 mode: 56 range: [48,75]
The median is 17.5
The median of these fourteen numbers is 84.
Let write the data in an increasing order: p q r s t.Since the median is 14, then r = 14, and we have: p q 14 s t.Since the mode is 11, then p = q = 11.Since the range is 9, then t - p = 9, t - 11 = 9, and t = 20.So, we have: 11 11 14 s 20.Since the mean is 25, we have:(11 + 11 + 14 + s + 20)/5 = 25(56 + s)/5 = 25 multiply by 5 to both sides56 + s = 125 subtract 56 to both sidess = 69So the data set is: 11 11 14 69 20
64 64 64 65 65 65 65 67 67 68 68 70 70 72 73 76 79 80. NB Place the numbers in RANK order. In this case it is already done #1 MODE ; is the term that occurs most frequently. In this case it is '65' , as there are four lots of '65' #2 MEDIAN ; is the term that occurs at the ABSOLUTE middle of the ranked order. Since there are eighteen terms, there is no absolute middle term. So we take the two middle terms that have the same number of terms to their side, that is terms nine & ten. They are 67 & 68. We then add these two together and halve the result. Hence (67 + 68) / 2 = 67.5. This is the median term. #3 MEAN ; is the sum of all the terms, which is the divided by the number of terms. Hence (64+64+64+65+65+65+65+67+67+68+68+70+70+72+73+76+79+80)/18 = 69' NB Another way of calculating the mean is ((3x64)+(4x65)+(2x67)+(2x68)+(2x70)+72+73+76+79+80)/18 = 69 NNB The word 'average' is casually used in the non-mathematical world, but the correct term is MEAN.

69, 78, 79, 88, 88, 88, 92, 93, 95, 98, 100 The mean is 88. The mode is 88. The range is 31.

The median of 2 numbers is the same as their mean, which is (69 + 78)/2 = 73.5

After putting them in order, cross out the 'ends' First 58 and 80 Then 58 and 74 You are left with 63 and 69 The median number is 66. The median is the number in the 'middle.'
It is: 69
69/100
100% means the whole amount, so 100% of 69 is 69.
