30, four groups collected data for pre-1982 pennies, two groups collected data for 1982 pennies, and four groups collected data for post-1982 pennies.\u00a0 After each group collected their data, the data was shared with the class and compared.<\/p>\n<p><a href=\"http:\/\/www.parentfunction.net\/blog\/wp-content\/uploads\/2015\/08\/Data-Lab.jpg\"><img loading=\"lazy\" decoding=\"async\"
