The median is the middle number of any given set when they are in order, least to greatest. If there is an even number of values, the median is the average of the middle two.
Ex. (10, 17, 20, 45, 68)
The median is 20.
In any given set, the mode is the number that appears most often. If no number appears more frequently than any other, there is no mode.
Ex. (10, 17, 20, 45, 68)
This set has no mode.
In any given set, the range is the smallest number subtracted from the largest number.
Ex. (10, 17, 20, 45, 68)
68 - 10 = 58
The range is 58.
In any given set, the mean is the average, which is the total of the numbers divided by how many numbers there are.
Ex. (10, 17, 20, 45, 68)
68 + 45 + 20 + 17 + 10 = 160
There are 5 numbers in this set.
160/5 = 32
The mean is 32.

Why do you use mean median and mode?
Together they tell you more about a series of numbers that any one of them. mean - average median - middle number if the numbers are listed from smallest to largest mode - most common number If your mean and median are close to one another, the statistical distribution is usually fairly good. Likewise, if the mode is close to the mean and median, it gives more verification that the distribution is a nice bell curve. The mode is probably the least useful of the three, as it assumes that there are many repeating numbers. In many actual situations, there aren't enough repeating numbers to make the mode of any value.
What does mean mode and median have in common?
They all describe data set or data sets,hey tell you how far apart they are from each other.
How do you find the range when your median is 20?
There is no direct relationship between the range and the median. So knowing that your median is 20 does not automatically give you the range. The median is just the middle value. That does not tell you what the first and last values are, which is what you need to know to find the range. The median of 19, 20 and 21 is 20, and the range is 2. The median of 4, 20 and 79 is also 20, but the range is 75. The median of 8, 16, 17, 23, 50 and 320 is also 20, but the range is 312. So, as you can see, the Median in no way can tell you what the range will be. You need to know what all of the numbers are, or at least the lowest and highest to know the range.
Measure of central tendency are measure?
3 common Measure of central tendency are the mean, median and the mode. They are measures in that they tell how how far any given value is from the center of a set of data. For example, the mean is commonly known as the average. Lets say you have the test scores, 25%, 50% , 75% and 100% You wonder how your 50% is compared to the mean? Since the mean is 62.5, you performed "below average." So that measure of central tendency measured how far you were from average. The others do the same thing.
When is the mean and median the same?
Well, there is no telling if the mean and median are the same. It can be, but most of the time it's not. You can't tell, but I am only in 5th grade, so I might be wrong.
What does 10.5 represent mean mode range or median?
It is not possible to tell without more information. As it is, it could be any of them.
What is the mode numbers 1 2 3 and 4?
From the number set 1, 2, 3, 4, I can tell that the range is 3, The mean is 2.5, the median is 2.5, yet there is absolutely no mode.
What does range tell us that mode does not?
Range is a measure of variation; mode is a measure of center. Range will tell you how much the data vary, mode does not tell you how much the data vary.

What is the median if the range is 8-20?
It's impossible to tell given the data. The median is the value dividing the half of the elements above the value and the half below it.

What would the function MODE in Excel tell us?
The MODE function finds the most commonly occurring number in a range of numbers.
When the median and mean are substantially different what does that tell you about the data?
I think it means that our data includes outliers.
A list of 7 numbers that have a range of 25 a mode of 15 and a median of ten?
Hmmm... are you sure there's only one possible combination? If you look at this combination:5, 7, 8, 10, 15, 15, 30The range is 25 (=30-5)The mode is 15 (most common number)The median is 10 (middle number)But that's far from the only combination - the 7 and 8 can be changed to any two numbers between the first number and the 10, and the 5 and 30 can even be moved around to anything within a 25-digit range. Still, as far as I can tell, the combination above is one of many possible answers
