You can put this solution on YOUR website! List A consists of numbers in the 40's through 60's
List B consists of numbers in the 40's through 60's.
Here is a back to back stem and leaf plot
LIST A . . . . . . . . . . . . . . . . . . . .LIST B
9, 8, 7, 6, 3, 1 . . . ./4/ . . . . . . . . . .4, 4, 9
8, 8, 8, 4, 2, 2 . . . ./5/ . . . . . . . . . .4, 5, 7, 8, 9, 9
7, 1, 0 . . . . . . . . /6/ . . . . . . . . . .0, 1, 2, 2, 3, 6
conclusions:
First 15 mornings are colder
median of list A = 52 > median of list B = 59
mode of list A = 58; mode of list B = 44, 59, and 62
mean of list A = 52.93 > mean of list B = 59.67
