All three are measures of what is called central tendency. They give you an idea where the "middle" is.
So in marketing you may want to know "the center value" of the people in a survey will purchase a product that you have promoted in some way. Here are some specific examples I made up to help see this.
The mean is the arithmetic average meaning you add up all the values of n people and divide by n.
This might be useful in a survey where the product is rated 1-5. Say 100 people rate it and your total points is 160 divided by 100 is 1.6 and that is the mean rating.
Probably not too good if 5 is good and 1 is poor. So the mean here tells you that the "average' rating is 1.6.
Now maybe you want to know where half the people are in relation to a certain question.
Say you ask "does price matter on a scale of 1 to 5 with 1 being not at all and 5 being price is very important. You ask a 10 people. The median will be the middle value.
For example.
The first three people you ask, call them person 1, person 2, and person 3 say 5
and people 4 and 5 say 1
people 6,7,8, 9 and 10 say 2
So now look at how many 1, 2 ,3 4, and 5 you have with the goal of finding the middle value, also known as the median.
2 ones
5 twos
0 threes
0 fours
3 fives
If you graphed this as a histogram, you could see the median visually as the middle value.
The point it the median gives you the middle value. In this example the median is (2+2)/2= 2 (and the mean is 2.7 just to see the difference)
The mode will tell you the most common value. That is to say what is the most likely answer.
So the mode of the data set above is 2 since there are 5 of them. This means "most" people would say it matters 2 on a 1-5 scale.
the median and mode are but the mean is not
The median is 9 and the mode is 18 and the mean is 11
mean: 1.7 median:1.7 mode: none
Mean, median, and mode are all equal in a normal distribution.
The median and mode cannot be outliers. For small samples a mode could be an outlier.
who discovered mean median and mode
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.

Mean, Median and Mode. They are three kinds of averages.
Mean, median, and mode are all equal in a normal distribution.
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.
