So, when finding range, you take the highest number and the lowest number of any system of numbers, (in our case, it's these sets of numbers)
{10, 14, 8, 19, 22, 13, 44}
{19, 16, 50, 18, 29, 23, 37}
{11, 9, 31, 29, 15, 17, 20, 24}
{12, 6, 24, 20, 44, 15, 29}
and subtract the highest from the lowest so,
{10, 14, 8, 19, 22, 13, 44} 44-8=36
{19, 16, 50, 18, 29, 23, 37} 50-16=34
{11, 9, 31, 29, 15, 17, 20, 24} 31-9=22
{12, 6, 24, 20, 44, 15, 29} 44-6=38
So the set of numbers with the greatest range would be the last one
