find mean and median 68,69,71,75,76,76,81,82,86,88,93,94,95,95,96 answer mean is 83 median is 82 ?
Right!
To find the median of a set of numbers:
1. Arrange the numbers in ascending order.
In the case of 4, 5, 6, 8, 11, and 17, the numbers are already in ascending order.
2. Determine the middle value(s).
Since the set contains an odd number of values (6 in this case), there is one middle value. In this case, the median is 6.
Therefore, the median of the set 4, 5, 6, 8, 11, and 17 is 6.
To find the mean (average) and median of a set of numbers:
1. Add up all the numbers in the set.
For the set 68, 69, 71, 75, 76, 76, 81, 82, 86, 88, 93, 94, 95, 95, 96, the sum is 1,234.
2. Calculate the mean by dividing the sum by the total number of values.
In this case, there are 15 values in the set, so the mean is 1,234 / 15 = 82.27 (rounded to two decimal places).
3. Arrange the numbers in ascending order.
The numbers in the set are already in ascending order.
4. Determine the middle value(s).
Since the set contains an odd number of values (15 in this case), there is one middle value. In this case, the median is 82.
Therefore, the mean of the set 68, 69, 71, 75, 76, 76, 81, 82, 86, 88, 93, 94, 95, 95, 96 is 82.27 (rounded to two decimal places), and the median is 82.
