The median is 86.5
90.5 is the median, as it is the number that is halfway between the two, or half of the total of the two numbers.
The median and mode are both 82. The mean is 84.6
83
When put into size order, the middle two numbers are 87 and 94. So the median is (87 + 94)/2 = 90.5
The mean is: 81.6 The median is: 81 Its mode is: 81 and 83 because its bi-modal
81.
It is 81
It is the middle value which is 81
It is 80.5, the number halfway between them. Median means "half of the numbers are above and half are below". With only two numbers we just split the difference. In this case the Median and the Mean are the same number - but this is not always the case. If our numbers were 80, 80, 81, 83, the Median would still be 80.5 but the Mean would be 81.
The median is 86.5
90.5 is the median, as it is the number that is halfway between the two, or half of the total of the two numbers.
The median and mode are both 82. The mean is 84.6
(79, 81, 82, 91, 93, 95, 95) The mean is 88 The mode is 95 The median is 91
The median is 81, the value halfway between the two middle values when they are arranged in order.
The median is 87.
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
