It is not: it may be better in some circumstances. The arithmetic mean and median are totally useless if the data are categoric. Think about a class of pupils recording what their favourite movie is and - unless they all choose the same film - try and figure out what the arithmetic mean or median could mean!
There are also situations - particularly with highly skewed data - where the median is a superior indicator of the central tendency compared with the mean.
Having said that, the arithmetic mean has some very important statistical properties and it has been studied extensively so there is a lot of information about it. It is beyond the scope of this site but if you are really interested you might want to read about the Central Limit Theorem. Warning: it is basic university level stuff.
The mean, median, and mode are all measures of central tendency. For symmetrical distributions they all have the same value. For assymetrical distributions they have different values. The mean is the average and the mode is the most likely value.
the median and mode are but the mean is not
The median is 9 and the mode is 18 and the mean is 11
The mode is the single number that appears most frequently among the numbers in the sampling. The median is the number at which exactly half of the numbers in the sampling are above it, and half are below it. The mean is the arithmetic average of all the numbers in the sampling.
mean: 1.7 median:1.7 mode: none
mode
Of these three, the median is most resistant.
It is the number in the middle of the set from least to greatest or greatest to least. If you're having trouble, remember this song: Mean, median, mode.Mean, median, mode. Here's what they are. Here's what they are. The mean is the one that you add then divide. The median is the one in the middle of the line. The mode is the one you see most of the time. Mean, median, mode. Mean, median, mode.
who discovered mean median and mode
The mean, median, and mode are all measures of central tendency. For symmetrical distributions they all have the same value. For assymetrical distributions they have different values. The mean is the average and the mode is the most likely value.
the median and mode are but the mean is not
The median is 9 and the mode is 18 and the mean is 11
The mean is 19. The median is 18. There is no mode.
The mean is the average. The median is the middle. The mode is the most common.
a single number, -3, is its own mean, median, and mode.
As the mean is greater than the median it will be positively skewed (skewed to the right), and if the median is larger than the mean it will be negatively skewed (skewed to the left)
