What is an outlier and what central tendency is affected always by an outlier?

An outlier is a number in a data set that is not around all the other numbers in the data. It will always affect the average; sometimes raising the average to a number higher than it should be, or lowering the average to something not reasonable.
Example:
Data Set - 2,2,3,5,6,1,4,9,31
Obviously 31 is the outlier. If you were to average these numbers it would be something greater than most of the numbers in your set due to the 31.

Which measure of central tendency is always part of any data set?
mean
Is an outlier always min or max value?
Not necessarily.
Is the best measure of central tendency always the mean?
Its the one most commonly used but outliers can seriously distort the mean.
Is a mean always an outlier?
Mean is theaverage of a bunch of numbers for example if the numbers were 7, 9 , and 11 first you add them all together to get 27 then you divide 27 by 3 because there are 3 numbers the answer would be 9 so the average/ mean is 9!Moxi19
Which measure of central location will the sum of the deviation of each value from the data's average will always be zero?
the mean %100
Which measure of central tendency will the sum of the deviations always be zero?
For which measure of central tendency will the sum of the deviations always be zero?
What is the smallest measure of central tendency in a positively skewed distribution?
If the distribution is positively skewed distribution, the mean will always be the highest estimate of central tendency and the mode will always be the lowest estimate of central tendency. This is true if we assume the distribution has a single mode.
For which measure of central tendency will the sum of the deviations always be zero?
Mean
Is Mean is more sensitive to skewness than the median?
If the distribution is positively skewed , then the mean will always be the highest estimate of central tendency and the mode will always be the lowest estimate of central tendency (If it is a uni-modal distribution). If the distribution is negatively skewed then mean will always be the lowest estimate of central tendency and the mode will be the highest estimate of central tendency. In both positive and negative skewed distribution the median will always be between the mean and the mode. If a distribution is less symmetrical and more skewed, you are better of using the median over the mean.
Which measure of central tendency is always part of any data set?
mean
What are the characteristics of mean as a measure of central tendency?
One of the characteristics of mean when measuring central tendency is that when there are positively skewed distributions, the mean is always greater than the median. Another characteristic is that when there are negatively skewed distributions, the mean is always less than the median.
Is an outlier always min or max value?
Not necessarily.
Is the best measure of central tendency always the mean?
Its the one most commonly used but outliers can seriously distort the mean.
What is optimal tendency?
optimal tendency is the real outcome of inborn talent bestowed by Almighty Creator which is always distinguish person to person.
When does boys voice changes?
It depends on the boy it should be around 12-16 but there is always outlier's, when his voice starts to crack then his voice is starting to change.
Why does the normality of sodium hydroxide change?
Because of water's nature to partially ionise itslef into hydronium and hydroxide ions, any solution of either a hydroxide or an acid will always be affected by this tendency, making the actual concentrations differ slightly from the expected ones.
Is an object's desire to not accelerate a force?
Object has not a "desire". It has tendency. It hasn't any tendency to accelerate, unless some impulse will be given to it along its way. The tendency of any object which has given it an impulse is to always slowing down if it is on a horizontal plane.
