Mean the average
Mode most often
Range subtract the smallest from the largest.
Median the middle number when they are lined up from the greatest to the least.

Examples:

Mean: if you had the number 10,10 you would add them up and get 20. Then divide by the number of how many you added(2).And the answer will be 10.

Mode: If you had the numbers 10,23,45,24,10 the mode will be the same number and that is 10.

Range:If you had the numbers 20,14,15,17,5,6 you will see what the smallest number and the biggest number is. 20 - 5 equals 15.

Median:If you had the numbers 10,12,14,13,11 you would line them up from greatest to the least. 10,11,12,13,14 and then see which number is in the middle and that is 12.

Hope this helps.

In statistics, mean has two related meanings:

the average in ordinary English, which is also called the arithmetic mean (and is distinguished from the geometric mean or harmonic mean). The average is also called sample mean.
the expected value of a random variable, which is also called the population mean.
Sample mean is often used as an estimator of the central tendency such as the population mean. However, other estimators are also used.

For a real-valued random variable X, the mean is the expectation of X. If the expectation does not exist, then the random variable has no mean.

The mean is the arithmetic average of a set of values, or distribution; however, for skewed distributions, the mean is not necessarily the same as the middle value (median), or most likely (mode). For example, mean income is skewed upwards by a small number of people with very large incomes, so that the majority have an income lower than the mean. By contrast, the median income is the level at which half the population is below and half is above. The mode income is the most likely income, and favors the larger number of people with lower incomes. The median or mode are often more intuitive measures of such data.

That said, many skewed distributions are best described by their mean - such as the Exponential and Poisson distributions.

An example
An experiment yields the following data: 34,27,45,55,22,34 To get the arithmetic mean

How many items? There are 6. Therefore n=6
What is the sum of all items? It is 217.
To get the arithmetic mean divide the sum by n ; it is 36.1666667

mean is the average number of all the numbers in a set.

For Example:

3 4 5 1 2 (add them up)

15/5 (divide by the amount of numbers there are in the set)

3 is the mean in your set of numbers

The average.

For example if the numbers were 5, 5.
You would add them all up so it would be 10.
Then divide it by the total number of numbers (2). I
The mean would be 5.

The mean is way of describing a group of numbers that can convey some sense of the group in a very simple way. Think of it as the average.
