MeanDeviation
MeanDeviation
[
list
]
gives the mean absolute deviation from the mean of the elements in
list
.
MORE INFORMATION
For the list
{
x
1
,
x
2
,
...
,
x
n
}
, the mean deviation is given by
, where
is the mean of the list.
MeanDeviation
handles both numerical and symbolic data.
MeanDeviation
[{{
x
1
,
y
1
,
...
}, {
x
2
,
y
2
,
...
},
...
}]
gives
{MeanDeviation[{
x
1
,
x
2
,
...
}], MeanDeviation[{
y
1
,
y
2
,
...
},
...
]}
.
MeanDeviation
works with
SparseArray
objects.
