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.
What is statistical average?
average is defined as a single value which has tendency to represent the data as a whole. averages are also called "measure of central tendency" or "measure of location"
What is mean and standard deviation?
They are statistical measures. For a set of observations of some random variable the mean is a measure of central tendency: a kind of measure which tells you around what value the observations are. The standard deviation is a measure of the spread around the mean.
Why you measure standard deviation?
The idea is to know how much the values "spread out" from the average.
What is strandard deviation?
It is a measure of how much individual values spread around the average.
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.
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.

The mean.

the mean
What does mean deviation tells us about the data?
It is a measure of how variable the data is. The average distance from the average.

What standard deviation tells us about a distribution?
It is a measure of the spread of the distribution: whether all the observations are clustered around a central measure or if they are spread out.
Why do you seldom use the mean or average deviation as a measure of dispersion?
because of grace severo
What provides a measure of central location for the data?
