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 calculate for the mean and median in relation to a sample?
Both the mean and median represent the center of a distribution. Calculating the mean is easier, but may be more affected by outliers or extreme values. The median is more robust.
How does the mean and the median compare?
mean is the average of a bunch of numbers. the median is the middle number of the bunch. if the bunch has an even amount of numbers, you average the middle 2 numbers to get the median.
What does an IQ of 116 mean?
You're in the top of the average group. so not exceptional, but better than most. the median IQ is about 100, which is perfectly average.
How does the mean compare to the median?
The mean and the median are both involved with a set of numbers. The mean refers to the average of the numbers. The median refers to the middle number of the numbers
Can you think of a situation where you'd use the mode over the median or mean?
You could use mode over median or mean when calculating probability. Mode calculates the greatest number of times an object or number will appear.
What are three ways of calculating an '' average ''?
Mean Median And Mode
Is the median affected by the mean?
The median is the value which seperates the upper and lower half of a set of numbers. The mean is the average value between two or more numbers. In calculating a set of numbers, specifically a set of averages, the median may indeed be effected by the mean.
Why calculate for the mean and median in relation to a sample?
Both the mean and median represent the center of a distribution. Calculating the mean is easier, but may be more affected by outliers or extreme values. The median is more robust.
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.
What is the definition of mean and median in math?
Mean is the average, and median is the middle number.
How does the outlier affect the mean and median?
The mean is better than the median when there are outliers.
Why would you use median instead of mean?
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.
What is the mean median and mode of a number?
The mean is the average. The median is the middle. The mode is the most common.
How does the mean and the median compare?
mean is the average of a bunch of numbers. the median is the middle number of the bunch. if the bunch has an even amount of numbers, you average the middle 2 numbers to get the median.
What are the advantages of calculating using mean mode and median?
So that you don't have as many different answers to work with
What do median mean in maths?
median is the middle number mean is average mode is most median is middle range is high - low
What does an IQ of 116 mean?
You're in the top of the average group. so not exceptional, but better than most. the median IQ is about 100, which is perfectly average.
