It shows the middle number in a number group rather than the average score in a number group. It isn't exactly better than the mean because they are often very close numbers.
But at other times, one number in a group messes up the mean if it is too low or too high, so you can get a better answer by finding out the median.

How does the outlier affect the mean and median?
The mean is better than the median when there are outliers.
Can the median ever be higher than the mean?
Yes, the median can be greater than the mean. It just depends on the values of the data. A simple series of 1,5,6 has 5 as the median, with a mean of 4.
Which landmark mean or median is the better indicator for an overall performance?
mean
What are some numbers that the mean is bigger than the median and the median is greater than the mode?
7,6,4,92,57,32
What number has a range of 5a median of 16 and a mean of 15?
A single number cannot have a range (other than 0), nor can it have a median that is different from its mean. A single number cannot have a range (other than 0), nor can it have a median that is different from its mean. A single number cannot have a range (other than 0), nor can it have a median that is different from its mean. A single number cannot have a range (other than 0), nor can it have a median that is different from its mean.
Why is the median a more stable measure of central tendency than the mean?
in general,mean is more stable than median but in the case of extreme values it is better to consider median a stable measure than mean.
How the values of mean and median relate to shape?
The question is how do the mean and median affect the distribution shape. In a normal curve, the mean and median are both in the same point. ( as is the mode) If a distribution is skewed, its tail is either on the right or the left. If a distribution is skewed the median may be a better value to use than the mean since it has less effect on the shape. Also is there are large outliers, the median has less effect and is better to use. So the mean has a bigger effect on the shape many times than the median.
How come the mean is less than the median?
If the distribution is not symmetric, the mean will be different from the median. A negatively skewed distribution will have a mean hat is smaller than the median, provided it is unimodal.
Can the mean be smaller than the median for a set of data?
Yes. If the lower values tend to be farther below the median than the highest values are above the median, the mean is smaller than the median. why are write wrong
When skewed right is the mean greater than median?
When a distribution is skewed to the right, the mean is greater than median.
When is the median more useful than the mean?
When the distribution has outliers. They will skew the mean but will not affect the median.
What is the nature of symmetry if median is greater than the mean?
Generally, when the median is greater than the mean it is because the distribution is skewed to the left. This results in outliers or values further below the median than above the median which results in a lower mean value than median value. When a distribution is skewed left, it is generally not very symmetrical or normally distributed.
What measure of center best represents data?
The answer depends on the type of data. The mean or median are useless if the data are qualitative (categoric): only the mode is any use. The median is better than the mean is the data are very skewed.
Can a mean average ever be higher than a median average?
Yes. If the predominant data are higher than the median, the mean average will be higher than the median average. For example, the median average of the numbers one through ten is five. The mean average is five and one-half.
Why is calculating the mean average better than the median or mode?
well when answering the mean you take the average of all the numbers so it be approxiamently around the answers and each number can affect the mean in many ways while a median is when you put the numbers in order and you get the middle number, because it is a middle the number can be far away from the beginning number or ending number. Mode is when the numbers appear the most and when picking mode it can be a dramatic change from the numbers around it. That is why calculating the mean average is better than take the median and mode, but sometimes some problems work better dealing with mode or median.
Why is the mean lower than the median?
because mean you add all the number and median you look for the number in the middel
Can the mean be greater than the median?
Yes.
