What else can I help you with?
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 is always part of any data set?
mean
Is the best measure of central tendency always the mean?
Its the one most commonly used but outliers can seriously distort the mean.
What disadvantage are there of the mean deviations?
The mean deviation of a set of observations is always zero and so conveys no information whatsoever!
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.
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?
Is there a measure of central location that the sum of deviations of each value will always be zero?
yes is it the median?
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
For which measure of central tendency will the sum of the deviations always be zero?
Mean
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
The sum of the deviations about the mean always equals what?
The sum of total deviations about the mean is the total variance. * * * * * No it is not - that is the sum of their SQUARES. The sum of the deviations is always zero.
A value that is typical or representative of the data is referred to as a measure of central location?
No, it is not, values typical of the data are always located at the extremes of all data frequencies.
Which measures of central location always have only one value for a set of grouped or ungrouped data?
Mean and median are the measures of central location that always have one value. This is true for a set of grouped or ungrouped data.
The sum of the deviations from the mean is always?
0 (zero).
Which measures of central location always have only one value?
median and mode
Which measure of central tendency is always part of any data set?
mean
