Perhaps using Map

In[5]:=
Clear[list]
list=Table[Random[],{10}]
Table[f[list[[n]]],{n,1,Length[list]}]
Map[f,list]


Out[6]=
{0.954944,0.449846,0.831544,0.485511,0.371568,0.588545,0.725658,0.19598,0.\
583527,0.814898}

Out[7]=
{f[0.954944],f[0.449846],f[0.831544],f[0.485511],f[0.371568],f[0.588545],f[0.\
725658],f[0.19598],f[0.583527],f[0.814898]}

Out[8]=
{f[0.954944],f[0.449846],f[0.831544],f[0.485511],f[0.371568],f[0.588545],f[0.\
725658],f[0.19598],f[0.583527],f[0.814898]}

Hope this helps
