You probably mean "average"- the "middle" or "expected" value of a data set.
The mean is the average value of the set. It is computed by adding all of the elements of the set, and then dividing that sum by the number of the items in the set.The median is the central, or middle, value in the set. It is computed by sorting the set and picking out the middle item or, if the number of items in the set is even, then by computing the mean of the middle two items.Not asked, but answered for completeness...The mode is the most probable value of the set. It is computed by plotting a distribution of the frequency of occurrence of each value in the set, and selecting the value, or values, with the highest occurrence in the set.
they are all three types of averages: the mean is worked out by adding up all of the results and dividing it by the amount of results added up the median value is just the middle value of the results the mode value is the value that occurs most in the results
It gets the middle value of a list of values. If you have a list of numbers, it returns the middle value as if they were in numerical order. If there is an odd amount of numbers, then it will give you one of the numbers that is in the list. If there are an even amount of numbers, then it will give the number halfway in value between the two middle numbers.
The Mean is the average of a given set of values. The Median is the value that has the same number of smaller values than the number of higher values, it is in the middle of them. In a symmetrical distribution the Mean is equal to the Median. In an asymmetrical distribution they have different value.
false
The median is the middle value of a list of numbers. In [1,6,34] the median value is 6.
You would use median instead of mean because the median doesn't find the average, it finds the middle value. Even if its not the middle of the range (the exact middle value between the lowest number and the highest number) it still is near to the middle value. The mean finds the average of all the numbers, like when a teacher average's her students' grades. Median is better to use when finding the middle value, not the average.
You mean 'core'. It's 0.
The median is the middle value of a list of numbers. In [1,6,34] the median value is 6.
The mean (average value), the median (middle value), and the mode (most frequently occurring value) are all important values.

It is the middle value of a set of values set out in ascending order.
It gets the middle value of a list of values. If you have a list of numbers, it returns the middle value as if they were in numerical order. If there is an odd amount of numbers, then it will give you one of the numbers that is in the list. If there are an even amount of numbers, then it will give the number halfway in value between the two middle numbers.
