Not always. An average is a value that acts as a good representative of a set of numbers. Mathematically, the average is the sum of all values, divided by the number of values there are. This is known as the arithmetic mean. There are also two other forms of average, other than the arithmetic mean. They are the Mode and Median. The Mode is the most common value in a list and the Median is the middle value when all are arranged in numerical order.
The mean is the most common form of average used. However there are occasions where a mode or median is better. If you have a lot of numbers and one number is huge compared to all the rest, then the mean is likely to give a number that is above nearly all the numbers, so is not very representative. A median or a mode will work better in that situation. The mean will often result in a number that is a decimal, rather than a whole number, even if the numbers are all whole numbers. A median or may result in a whole number, though not always.
A mode is good when there are lots of numbers that are in groups of the same, as it will show which number is most common. If there is not one most common number, then there is no mode.
yes. the mean is the average.

Are average and range the same thing?
No, they are not the same thing. Mean and average are the same thing.
Is the point estimate the same as the average?
No. The average of a dataset is the point estimate for the mean of the population.
Does standard deviation and mean deviation measure dispersion the same?
No. The average of the deviations, or mean deviation, will always be zero. The standard deviation is the average squared deviation which is usually non-zero.
What is the average IQ for 42 year olds?
100. an intellegence quotient (IQ) is a statistical measure that compares an individual against the average of indiviudals the same age. so, the average is always 100 regardless of the age. However, the average/score of a 42yo is not the same as 30yo... for example, an IQ score of 100 does not mean the same thing for a 16yo as it does for a 50yo, they are age specific.
What does an IQ score of 80 mean?
It means that your IQ score is 20 points below the average, the same amount as a person with an IQ of 120 would be above the average.
Which two math terms means about the same median ratio mean average?
Mean and average are the same.
Are average and range the same thing?
No, they are not the same thing. Mean and average are the same thing.
How do you calculate mean average deviation?
The mean average deviation is the same as the mean deviation (or the average deviation) and they are, by definition, 0.
Is the average and the mean of a number the same thing?
Yes they mean the same thing.
What is another name for average?
The mean is the same thing as the average of a group of numbers
What is the diffenition of mean in math?
The word "mean" in math means the same thing as average. Mean is just a nickname for average.
Is the average the same thing as the mean?
A Mean is a type of average, but there are other kinds of averages too, Modes and Medians.
Is mean age the same as average age?
yes it is because you do the same thing
Is the point estimate the same as the average?
No. The average of a dataset is the point estimate for the mean of the population.
What is the mean 52 and 84?
(52 + 84) ÷ 2 = 68Note: mean is the same as average.
Is the geometric mean the same as the mean or average of two numbers?
Not usually. Given numbers a and b, the mean or average is (a + b)/2 but the geometric mean is sq rt (a X b). If both a and b equal 1, the results are the same.
Another term used to describe the average is called the?
The "average" of the population of samples is the same as their "mean".
