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.
Find the mean for the following group of data items 8 3 6 5 2 7 6 2 what is the mean round to 3 decimal places as needed?
Mean = (8+3+6+5+2+7+6+2)/8 = 39/8 = 4.875
5 2 thirds to a decimal?
If you mean 5 + 2/3, that is 5.666666666....... If you mean 5 lots of 2/3, that is 10/3 = 3 1/3 = 3.3333333333........
What is the mean of 3 5 4 5 6 5 3 2 5 2?
5
Can the median answer be a decimals like 5.5?
Yes.Two ways:the data contains non-integer items, eg the median of {1, 1.3, 1.567, 2.4, 5} is 1.567;the data contains an even number of data items. In this case, the median is the mean average of the middle two, which may not be an integer, eg the median of {1, 2, 3, 4} is the mean average of {2, 3} = (2+3)/2 = 2.5

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 mean absolute deviation for the data values 1 2 2 3 4 5 5 5 5 6?
Mean is 3.8 Mean Absolute Deviation is 1.44
Find the mean for the following group of data items 8 3 6 5 2 7 6 2 what is the mean round to 3 decimal places as needed?

What is the median and mean1 1 2 2 2 3 3 3 3 4 4 4 5 5 6 7?
The data {1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 7} has: Median: Thee are 16 data items, so the median is the mean average of the middle two, ie the 8th and 9th numbers: median is (3 + 3) / 2 = 3 Mean: (1 + 1 + 2 + 2 + 2 + 3 + 3 + 3 + 3 + 4 + 4 + 4 + 5 + 5 + 6 + 7) ÷ 16 = 55 ÷ 16 = 37/16 = 3.4375
What can be expressed mean in a math problem?
When a math problem asks for a mean it does not necessarily refer to the emotion of mean. Finding the mean of a group of data is what it is referring to also the mean can also be called the average. To find the mean or average you take all your data and add them together. Then divide the sum of the data by the number of digits in the data. Ex. 2, 5, 7, 3, 2+5+6+3=16 16 divided by 4 equals your mean of 4.
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.
What is the median of 2 3 4 5 7 9?
When there is an even number of data items the median is the mean average of the middle two. → median of {2, 3, 4, 5, 7, 9} = (4 + 5)/2 = 9/2 = 4.5
How mean of a data set is always one of the data points in a set of data. Explain?
The mean of a set of data is the sum of all those data values, divided by the numbers of values in the set. For instance, if we had 1, 3 and 5, the mean would be (1+3+5)/3 = 3. The mean doesn't always have to be one of the data points in the set. For instance, if we had the data 1, 6, 7, 7, 8. The mean would be (1+6+7+7+8)/5 = 5.8, even though 5.8 isn't one of the values in the set.
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.
5 2 thirds to a decimal?
If you mean 5 + 2/3, that is 5.666666666....... If you mean 5 lots of 2/3, that is 10/3 = 3 1/3 = 3.3333333333........
How is the mean found for a set of data?
The mean of a set of data is the average. You find it by adding the numbers and dividing by the amount of numbers. For example 1, 2, 3, 4, 5, 6, 7 mean = 1+2+3+4+5+6+7 / 7 28/7 (28 is the sum of the numbers, 7 is the amount of numbers in the set) The mean is 4.
