The coded deviation method is a statistical technique used to analyze data by transforming the original values into coded forms, typically through normalization or standardization. This process allows researchers to simplify the comparison of different datasets by scaling them to a common range or mean. It is particularly useful in experimental designs and optimization problems, enabling clearer insights into the effects of various factors on outcomes. By applying coded deviations, analysts can reduce the impact of units of measurement and focus on the relative differences among variables.
Differing from standard deviations, the coded deviation method finds the mean of grouped data from the assumed mean using unit deviations. This is a shorter way to find the mean.
A simple method is the inter quartile range. A more sophisticated option in the standard deviation.
The mean average deviation is the same as the mean deviation (or the average deviation) and they are, by definition, 0.
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
No. The mean deviation is 0. Always.

Strictly speaking, none. A quartile deviation is a quick and easy method to get a measure of the spread which takes account of only some of the data. The standard deviation is a detailed measure which uses all the data. Also, because the standard deviation uses all the observations it can be unduly influenced by any outliers in the data. On the other hand, because the quartile deviation ignores the smallest 25% and the largest 25% of of the observations, there are no outliers.
What is mean deviation and why is quartile deviation better than mean deviation?
A standard deviation for a sample makes a judgment on the whole data set whereas the population standard deviation uses the shole data set. If the questions says for example, a sample of 50 peoples height was taken... you would use the sample method but if you were asked : "Everyone in the class had their height measured" you could use the population method Hope that helps
Information is not sufficient to find mean deviation and standard deviation.
mean deviation =(4/5)quartile deviation

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.
No. The mean deviation is 0. Always.
The standard deviation is the standard deviation! Its calculation requires no assumption.
