Apply multiple functions to same list

Also,

y = {1, 2, 3, 4, 5, 6, 7};

#[y] & /@ {Max, Min, Median, Mean}

(*  {7, 1, 4, 4}  *)

EDIT: comparing the timings:

n = 100000;

Do[Through[{Max, Min, Median, Mean}[y]], n] // AbsoluteTiming

(*  {0.548089, Null}  *)

Do[#[y] & /@ {Max, Min, Median, Mean}, n] // AbsoluteTiming

(*  {0.709574, Null}  *)

Through is more efficient, at least in this case.

You can use Through.

Through[{Max, Min, Median, Mean}[y]]

(* {7, 1, 4, 4} *)

Hope this helps.

Query offers a reasonable syntax for this case:

y = {1, 2, 3, 4, 5, 6, 7};

y // Query[{Max, Min, Median, Mean}]
(* {7, 1, 4, 4} *)

Query has the nice feature that we can apply such lists of functions at deeper levels without too much additional thought:

ys = {{1, 2, 6}, {4, 5, 9}, {10, 20, 60}};

ys // Query[All, {Max, Min, Median, Mean}]
(* {{6, 1, 2, 3}, {9, 4, 5, 6}, {60, 10, 20, 30}} *)
