### What is mean and median?

mean~ all the numbers in the data added together divided by the
number of data. The mean is the same as the average. median~ the
exact middle of the set of data. Example: 1,1,2,2, the median is
1.5 mean- the average median- the middle number in a set of
numbers in a group.
Example of Median-
1,3,5,7,9,4,5 (put them in order and list them from least to
greatest)
1,3,4,5,5,7,9
the median is 5!

### Advantages and disadvantages of median in statistics?

MEDIAN
Use the median to describe the middle of a set of data that
does have an outlier.
Advantages:
• Extreme values (outliers) do not affect the median as
strongly as they do the mean.
• Useful when comparing sets of data.
• It is unique - there is only one answer.
Disadvantages:
• Not as popular as mean.

###### Asked in Math and Arithmetic, Statistics

### How are mean and median alike?

The mean of a set of data is all the values in that data added
together and then divided by the number of values. For instance, if
you had the data set 1, 3, 4, 6, 8, you would add them all up to
get 22, and then divide by 5 to get 4.4 which is the mean. The
median is the middle value of all data values. In the above data
set, that is 4, and so 4 would be the median. Mean and median are
alike in that they both attempt to find the "middle" of the data,
and are both considered averages.
