Describe what could happen to these measurements if the data set is combined with another data set that has a mean of 28, a median of 30, and a mode of 25.
Person solving problem knows the definitions of mean, median, and mode.
Person solving problem can calculate mean, median, and mode of data. Another point known is that in data set one the total of the members must be a multiple of 25 and in set two the sum must be a multiple of 28. The data set for the above graph was determined by entering figures into a Microsoft Excel spreadsheet. The first three columns were set to determine the mean, median and mode of the placed data. Students solving the problem can then randomly enter their data and watch as the mean, median, and mode change with each data input.
