Why graph on computers? Neatness Accuracy Quickness

OPT--M&M lab As a group, write your names on a dixie cup, then count out 36 M&M’s. Sort the M&M’s by color and make a data table. Tell Mrs. McMullan how many reds you have. Make a data table and bar graph (circle graph later) for the 36 M&M’s (do not eat any until everything is finished and checked—tomorrow?) Part 2: make with computer (Excel)—in a couple of days
