We are doing mean, median and mode. If one collected data on the depth, in feet,of 12 different digs from his sources, and they shared their data as: 110, 250, 230, 230, 122, 286, 115, 299, 98, 142, 188, 198. How would I work to figure the mean of this data? An rounded to two decimal places, like this: 42.53.
