The sum of the deviations from the mean is always?
0 (zero).
What is the sum of the deviations from the mean?
The sum of standard deviations from the mean is the error.
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?
The sum of the deviations from the mean is always zero?
The definition of the mean x of a set of data is the sum of all the values divided by the total number of observations, and this value is in turn subtracted from each x value to calculate the deviations. When the deviations from the average are added up, the sum will always be zero because of the negative signs in the sum of deviations. Going back to the definition of the mean, the equation provided (x = Σxi/n) can be manipulated to read Σxi - x = 0
Which measure of central location will the sum of the deviations of each value from the data's average always be zero?
the mean

0 (zero).
What is the sum of the deviations from the mean?

For which measure of central tendency will the sum of the deviations always be zero?
Mean
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 Sum of deviation from the mean is?
The sum of deviations from the mean, for any set of numbers, is always zero. For this reason it is quite useless.

For which measure of central location will the sum of the deviations of each value from the data's average will always be zero?
The mean.
Which measure of central location will the sum of the deviations of each value from the data's average always be zero?
the mean
What does the sum of the deviations from the mean equal?
Zero.
What is the sum of all deviations of a data value from a measure of central location that will always be zero?
Difference (deviation) from the mean.
In any distribution is the sum of the squared deviations from the mean always equal to zero?
No. It cannot be. Remember that when you square a negative number it becomes a positive number. Thus all squared deviations are positive and their sum must be positive.
Why do deviation in a data set sum to zero?
They don't necessarily. Deviations from the median in an asymmetric data set will not sum to 0. The mean is the sum of observations divided by the number of observations and some simple algebra will show that the sum of deviations from this equals 0.
