Difference between the actual and planned for a effort is known as effort deviation.
What is mean deviation and why is quartile deviation better than mean deviation?
Information is not sufficient to find mean deviation and standard deviation.
Standard deviation can be greater than the mean.
Yes. Consider the definition of the standard deviation. It is the square root of the variance from the mean. As a result, it can be said that the standard deviation is dependent on the mean.

What is mean deviation and why is quartile deviation better than mean deviation?
mean deviation =(4/5)quartile deviation
Information is not sufficient to find mean deviation and standard deviation.
The mean deviation from the median is equal to the mean minus the median.
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.
Standard deviation is a measure of variation from the mean of a data set. 1 standard deviation from the mean (which is usually + and - from mean) contains 68% of the data.
Mean and standard deviation are not related in any way.
Standard deviation can be greater than the mean.
No. A small standard deviation with a large mean will yield points further from the mean than a large standard deviation of a small mean. Standard deviation is best thought of as spread or dispersion.
Yes. Consider the definition of the standard deviation. It is the square root of the variance from the mean. As a result, it can be said that the standard deviation is dependent on the mean.
If I have understood the question correctly, despite your challenging spelling, the standard deviation is the square root of the average of the squared deviations while the mean absolute deviation is the average of the deviation. One consequence of this difference is that a large deviation affects the standard deviation more than it affects the mean absolute deviation.
