something like below, not tested,

function calculate_avg(){
   var child_rows = frm.doc.average_marks;
   var total_marks = 0;
   var total_criteria = 0;
   for(var i in child_rows) {
       total_marks += child_rows[i].marks;
       total_criteria += child_rows[i].criteria;
   //calculate average
   var avg = total_marks / total_criteria;
   frm.doc.average_mark = avg;

frappe.ui.form.on("Child Doctype Name", "criteria", function(frm, cdt, cdn) {
