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.
No, they are not the same thing. Mean and average are the same thing.
No. The average of a dataset is the point estimate for the mean of the population.
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.
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.
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.
Mean and average are the same.
No, they are not the same thing. Mean and average are the same thing.
The mean average deviation is the same as the mean deviation (or the average deviation) and they are, by definition, 0.
Yes they mean the same thing.
The mean is the same thing as the average of a group of numbers
The word "mean" in math means the same thing as average. Mean is just a nickname for average.
A Mean is a type of average, but there are other kinds of averages too, Modes and Medians.
yes it is because you do the same thing
No. The average of a dataset is the point estimate for the mean of the population.
(52 + 84) ÷ 2 = 68Note: mean is the same as average.
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.
The "average" of the population of samples is the same as their "mean".
