Mean
Mean
[
list
]
gives the statistical mean of the elements in
list
.
Mean
[
dist
]
gives the mean of the symbolic distribution
dist
.
MORE INFORMATION
Mean
[
list
]
is equivalent to
Total
[
list
]/
Length
[
list
]
.
Mean
handles both numerical and symbolic data.
Mean
[{{
x
1
,
y
1
,
...
}, {
x
2
,
y
2
,
...
},
...
}]
gives
{Mean[{
x
1
,
x
2
,
...
}], Mean[{
y
1
,
y
2
,
...
}]}
.
Mean
works with
SparseArray
objects.
