What is the average of 2 and -3 and -4?
The average of 3 numbers is their sum divided by the number of data in the data set (in this case 3). 2+-3+-4=-5. Their average is 5/3, or 1 2/3, or 1.6666666 with the 6 repeating.
What is the median of the following numbers 8 6 9 2 5 3 7?
First: sort the data into order: {8, 6, 9, 2, 5, 3, 7} → {2, 3, 5, 6, 7, 8, 9} Then the median is the middle data item, or the mean average of the middle two if there are an even number of data items. There are 7 data items → the middle one is the (7 + 1) ÷ 2 = 4th data item which is 6.
How do you average numbers?
You would add all the numbers together then divide it by the number of numbers in the data set. Ex:2,4,6,8 2+4+6+8=20 There are 4 numbers in the data so: 20/4=5 the average is 5
How do you find the median if the amount of data is even?
If the number of data is even, the median can be found by listing all the data from least to greatest (or from greatest to least, it doesn't matter), crossing out one per side until you are left with two data, and then averaging the two data. For example: 1 2 3 4 5 6 First you cross out 1 and 6, then 2 and 5, so you are left with the middle two, 2 and 3. You average them by adding them together and then dividing by 2. 3 + 2 = 5 5/2 = 2.5 The median is 2.5.
What is the average of6 2 8 6 and 3?
(6+2+8+6+3)/5 =(6+10+6+3)/5 =(12+10+3)/5 =(12+13)/5 =25/5 =5 Five is the average of 6, 2, 8, 6, and 3.

What is the mean average of this data 5 8 9 6 2?
What is the mean of 5 9 3 3 9 6?
What is the median of the following numbers 8 6 9 2 5 3 7?

How do you work out speed using mean and median?
Mean is the average of a set of data points = (Sum of all data) / Quantity of DataMedian is the middle of a set of data points = Data whose index is the integer nearest ((Number of Data+1) / 2)Example Data:2, 3, 5, 3, 2The mean = (2+3+5+3+2)/5 = 15/5 = 3The median = Index((5+1)/2) = Index(6/2) = Index(3). The third item on our list is 5.
What is the median of 5- 6- 15- 16?
Since there are an even number of data, the median will be the average of the middle two.So, median = (6+15)/2 = 10.5

What is the average of6 2 8 6 and 3?
(6+2+8+6+3)/5 =(6+10+6+3)/5 =(12+10+3)/5 =(12+13)/5 =25/5 =5 Five is the average of 6, 2, 8, 6, and 3.
What is the average of 2 6 7?
5
How do you find the median if there are two data items in the middle?
take the average of them so say my points are: 1,2,3,3,4,6,7,8,9,9 then the median is between 4 and 6 so (4+6)/2 is 5
What is the average of two thirds one half and five sixths?
The average is 2/3.---------------------2/3 + 1/2 + 5/6 = 4/6 + 3/6 + 5/6 = 12/6 =2.Divide by 3: 2/3.
How do you compute averages?
Simply add up all of the data you have. Then find how many pieces of data you have and divide the first number by this number. Example: 5 bits of data: 1 5 6 9 4 Average is (1+5+6+9+4) divdided by 5 = 5
