const scores2=45+87+98+100+86+94+67+88+94+95;
console.log(scores2)



function getAverage(scores){
  return scores1/total1;
}

function getAverage2(scores){
  return scores2/total2;
}


const getAverage1 =[92, 88, 12, 77, 57, 100, 67, 38, 97, 89]
const getAverage2 =[45, 87, 98, 100, 86, 94, 67, 88, 94, 95]

let total1 = getAverage1.length
console.log(total1);
let total2 = getAverage2.length;
console.log(total2);

console.log(getAverage([92, 88, 12, 77, 57, 100, 67, 38, 97, 89]));
console.log(getAverage([45, 87, 98, 100, 86, 94, 67, 88, 94, 95]));

you are being asked to complete the getAverage function which takes in an array of test scores and returns the average score.
use this to find the average.
average = sum of all scores / total number of scores

3

I think I need a for loop, is that correct?

4

yes you need a for loop for this

5

you need the loop to iterate over the scores, when you’re done with the loop the next thing is to find the average of the scores.
