Draw a stem-and-leaf plot for the data set. (Enter numbers from smallest to largest separated by spaces. Enter NONE for stems with no values.) Data set A: The annual wages of employees at a small accounting firm are given in thousands of dollars. 50 36 21 27 32 19 36 35 34 14 31 60 15
First sort the data from smallest to largest. Tell me what you get.
I get: 14,15,19,21,27,31,32,34,35,36,36,50,60
good
notice how each number is a two digit number the tens digit starts at 1 and goes to 6
great, thanks. Next?
so let's set up the stems we have a T table like this with "stem" and "leaf" as headers |dw:1410650401972:dw|
then in the stem column, we write the numbers 1 through 6 |dw:1410650452924:dw|
Ok...done
optionally you can draw these horizontal lines, but you don't have to I'm doing so to help separate things |dw:1410650503385:dw|
our sorted data set is 14,15,19,21,27,31,32,34,35,36,36,50,60
OK...thanks
focus on the numbers that have a tens digit of 1 those numbers are 14, 15, 19 the stem of "1" represents all numbers that have a tens digit of 1 the leaves of 14,15,19 are 4, 5, 9 in that order and they go in the "stem = 1" row |dw:1410650588359:dw|
then for 21,27, we just add in 1 and 7 to the stem for 2 |dw:1410650622092:dw|
then we do 31,32,34,35,36,36 so we add on: 124566 |dw:1410650658938:dw|
