To answer these questions, first we need to sort the list.
78 83 85 87 94 96
The mean is the sum divided by the number of data.
mean = (78+83+85+87+94+96)/6 = 523/6 = 87.17
The median is the middle number.
Since there are an even number of data, we use the average of the middle two numbers.
median = (85+87)/2 = 86
The mode is the most common number. Since no number appears more than once, there is no mode.
83
78
Range: 187 Median: 67 Mode: 83, 61
The mean is 83.
78.4
The mean is: 81.6 The median is: 81 Its mode is: 81 and 83 because its bi-modal
The mean is 85.5 The median is 88.5 The mode is 90
Mean: 69 Median: 67 Mode: 83, 61
Mean: 83 Median: 62 There is no mode.
83
78
the mode and median are completely different the mode is the number that occurs the most and the median is the number in the middle of the data chart ex. 14, 24, 24, 35, 83, 92, 123 the mode is 24 and the median is 35 hope it helped
Range: 187 Median: 67 Mode: 83, 61
meanAdd up the numbers and divide by how many there are: 87+75+89+81+90+73+85+96+65+92+78+79+83+85+79+90+86+72+74+88+81+85 = 1813There are 22 numbers.⇒ mean = 1813 ÷ 22= 829/22≈ 82.41medianSort the numbers into order; the median is the middle number (if an odd number of numbers) or the mean of the middle two (if an even number of numbers): Sorted: 65, 72, 73, 74, 75, 78, 79, 79, 81, 81, 83, 85, 85, 85, 86, 87, 88, 89, 90, 90, 92, 96There are 22, so the median is the mean of the middle two which are the 11th (83) and 12th (85) numbers:⇒ median = (83+85) ÷2= 84modeThe number which appears the most often. Having sorted the list for the median, it can be seen that the one with the highest frequency appears three times: ⇒ mode = 85
The mean is 83.
78.4
70.5 The median is the middle value, so I'll have to rewrite the list in order: 53 54 59 62 64 65 66 68 70 71 75 78 83 83 86 90 91 94 There are 18 numbers in the list, so there is no "middle" number. So, you take the average of the middle two numbers, which is 70 and 71. So the median is 70.5.
