Mean = 83.91666666667
Median = 85 (in this case, we have even numbers so add the 2 numbers in the center which is the 83 and 87 and then divide by 2)
Mode = 89 (89 appears 2 times)
Mean Formula:
mean = Summation of all the numbers and then divide by how many the numbers
Median Formula
median = 1. Arrange your numbers in numerical order.
2.Count how many numbers you have.
3.If you have an odd number, divide by 2 and round up to get the position of the median number.
3.If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.
Mode Formula
mode = To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.
