Week 1 Checkpoint

Calculating Average, Highest & Lowest

scores = [75, 100, 85, 65, 84, 87, 95]

def average(array)
  total = 0

  array.each {|i| total += i}
  total/array.length

end

def highest(array)

  first = array[0]
  array.each do |i|

    if i > first
      first = i
    end

  end
  return first

end

def lowest(array)
  first = array[0]
  array.each do |i|

    if i < first
      first = i
    end
  end
  return first

end

puts "Average Score: #{average(scores)}"
puts "Highest Score: #{highest(scores)}"
puts "Lowest Score: #{lowest(scores)}"

The only thing I'd add is to convert to floats instead of integers so that you get more precise results
