Question

What is the mean, median, mode, and range of;
34, 28, 11, 42, 25, 12, 56

Answer 1

1. Order your numbers:
11, 12, 25, 28, 34, 42, 56

2. Mean is adding all of the numbers together and dividing that total by the amount of numbers:
11 + 12 + 25 + 28 + 34 + 42 + 56 = 208
208 / 7 = 29.7

3. Mode is a number that is repeated in a sequence of numbers:
There are no repeated numbers so there is NO mode

4. Range is the smallest number subtracted from the largest number of the sequence
56 - 11 = 45

5. Median is simply the middle number in a sequence of ordered numbers:
So 28 would be your median.

Hope this is helpful!

Answer 2

Hello!

Let's 1st start with the 'Mean": We know that the mean is the average of the numbers: a calculated "central" value of a set of numbers. To calculate: Just add up all the numbers, then divide by how many numbers there are.

So in this Case, the mean of these number would be 29.7 because we added all of the number's and divided them by 7, which is how many numbers there are in total.

Now, What is the "Median"? Well, to find the median, we know that we have to place the numbers we are given in value order and find the middle number. Example: find the Median of {13, 23, 11, 16, 15, 10, 26}. ... The middle number is 15, so the median is 15. (If there are two middle numbers, you average them.)

So in this Case, the "Median" of these numbers would be "28" because we ordered all of the numbers like this: 11, 12, 25, 28, 34, 42, 56 and found the middle number which was "28".

Now, what is the "Mode" of all of this? Well, to find the mode, we know that it's the number which appears most often in a set of numbers. Example: in {6, 3, 9, 6, 6, 5, 9, 3} the Mode is 6 (it occurs most often).

But in this case, there is "NO" mode because there is no number repeated as seen above.
