Homework Help: stats(help)

Posted by sue on Thursday, March 5, 2009 at 6:19pm.

These are the numbers of wins for the 30 NBA teams for the 2004-2005 NBA season.
45 43 42 33 33 54 47 44 42 30 59 45 36 18 13 52 49 44 27 26 62 50 37 34 34 59 58 51 45 18
I am supposed to create a grouped frequency table for this data.
I found my range is 62-12=49
I decided that I want to create 7 groups 49/7=7
However when I created my first column, class interval I am missing a number. this is what I got:
13- 19,20-26,27-33,34-40,41-47,48-54,55-61

Please tell me what I am doing incorrect.
