Discussion thread for Temperature variations.

When I try to solve this problem using Julia I get the following error,

Julia code

```
function temperature_statistics(T)
mean = sum(T)/length(T)
std = sqrt(sum((T .- mean).^2)/length(T))
return mean, std
end
```

```
ERROR: LoadError: MethodError: no method matching Array{Float64,1}(::Array{Float64,2})
You might have used a 2d row vector where a 1d column vector was required.
Note the difference between 1d column vector [1,2,3] and 2d row vector [1 2 3].
You can convert to a column vector with the vec() function.
Closest candidates are:
Array{Float64,1}(::AbstractArray{S,N}) where {T, N, S} at array.jl:562
Array{Float64,1}() where T at boot.jl:425
Array{Float64,1}(!Matched::UndefInitializer, !Matched::Int64) where T at boot.jl:406
...

Other Julia users have tried alternate solution, but the error persists. More information here: Trying to understand reported error - Usage - JuliaLang
