Consider the given data set consisting of the number of texts sent by students during lunch.
0,2,3,5, 5, 7, 8, 8, 8, 8, 9,9.9,9,10,10, 10, 10, 10, 11, 11, 11, 11, 11, 12, 12, 12, 12, 12, 12
The mean for this data set is 8.9 and the median is 10.
One student texted 48 times during lunch and we added her data point to the original data
set so that it now looks like this:
0,2,3,5,5,7,8, 8, 8, 8, 9,9.9,9,10,10, 10, 10, 10, 11, 11, 11, 11, 11, 12, 12, 12, 12, 12, 12, 48
what effect will this new data point have on the spread of the data?
