Question

{5, 6, 1, 1, 4, 7, 2, 1} Calculate the median of the original dataset and the median of the new dataset with the data for 4 pairs it shoes added.

Answer 1

First, the original data sorted is {1, 1, 1, 2, 4, 5, 6, 7}. With 8 values the median is the average of the 4th and 5th values:
median(original) = (2 + 4)/2 = 3.

For the new dataset: I need the actual values of the "4 pairs" you added. If those 4 pairs mean 8 more numbers, the combined dataset will have 16 values, so the median will be the average of the 8th and 9th values in the sorted combined list.

Tell me the 4 pairs (or the 8 numbers) you added and I will compute the new median. If you want, I can also show the computation with an example set of added pairs.
