An outlier can significantly affect the mean absolute deviation (MAD) by increasing its value. Since MAD measures the average absolute differences between each data point and the mean, an outlier that is far from the mean will contribute a larger absolute difference, skewing the overall calculation. This can lead to a misleading representation of the data's variability, making it seem more dispersed than it actually is for the majority of the data points. Consequently, the presence of outliers can distort the interpretation of the data's consistency and spread.
None.The mean of a single number is itself.Therefore deviation from the mean = 0Therefore absolute deviation = 0Therefore mean absolute deviation = 0None.The mean of a single number is itself.Therefore deviation from the mean = 0Therefore absolute deviation = 0Therefore mean absolute deviation = 0None.The mean of a single number is itself.Therefore deviation from the mean = 0Therefore absolute deviation = 0Therefore mean absolute deviation = 0None.The mean of a single number is itself.Therefore deviation from the mean = 0Therefore absolute deviation = 0Therefore mean absolute deviation = 0
An outlier can significantly affect the Mean Absolute Deviation (MAD) because MAD is calculated based on the average of the absolute deviations from the mean. Since an outlier deviates far from the mean, it increases the overall average of these deviations, leading to a higher MAD. This can distort the representation of variability within the dataset, making it appear more spread out than it truly is when excluding the outlier. Consequently, the presence of outliers can mislead interpretations of data dispersion.
You calculate the mean.For each observation, you calculate its deviation from the mean.Convert the deviation to absolute deviation.Calculate the mean of these absolute deviations.
no the standard deviation is not equal to mean of absolute distance from the mean
The range and mean absolute deviation are: Range = 29 Mean absolute deviation = 8.8
The mean is "pushed" in the direction of the outlier. The standard deviation increases.

The mean absolute deviation of this problem is 6.
The mean absolute deviation is 28.5

You calculate the mean.For each observation, you calculate its deviation from the mean.Convert the deviation to absolute deviation.Calculate the mean of these absolute deviations.
The median is least affected by an extreme outlier. Mean and standard deviation ARE affected by extreme outliers.
no the standard deviation is not equal to mean of absolute distance from the mean
The range and mean absolute deviation are: Range = 29 Mean absolute deviation = 8.8
interquartile range or mean absolute deviation.
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.
The mean deviation of any set of numbers is always zero and so the absolute mean deviation is also always zero.
