Hello Marcelo,

The Formulas question type does not have this function. However, it has other functions with which you can built many things. For example, the following code calculates the highest frequency in a list of numbers.

The code can certainly be more complete. For example, if there are two or more numbers that repeat most often, the code displays only one. But I only developed it as a demo. Feel free to modify it according to your needs.

Random variables
  r0={1:10};
  r1={1:10};
  r2={1:10};
  r3={1:10};
  r4={1:10};
  r5={1:10};
  r6={1:10};
  r7={1:10};
  r8={1:10};
  r9={1:10};
  r10={1:10};
Global variables  
  a = [r0, r1, r2, r3, r4, r5, r6, r7, r8, r9, r10];
  vmax=a[0];
  b = fill (len(a),1);
  nmax = 1;
  ii=0;
  for ( i : b ) {
    jj = 0;
    n = 0 ;
    for ( j : b )  {
      n = ( a[ii] == a[jj] ) ? n + 1 : n ;
      jj = jj +1 ;
    }
    nmax = (n >= nmax) ? n : nmax ;
    vmax = (n >= nmax) ? a[ii] : vmax ;
    ii = ii + 1;
  } ;
Question text
  [{a[0]},{a[1]},{a[2]},{a[3]},{a[4]},{a[5]},{a[6]},{a[7]},{a[8]},{a[9],{a[10]}]<br>
  Highest frequency => number {vmax} ({nmax} times)

Here's what you'll get:
