What is the difference between th two given data stes?which measure of center changed the most, mean , meadian or mode? which measure of center changed the least?
There is no data given, so we cannot respond adequately.
However, deviant scores always effect the mean the most. It helps if you think of the mean as a fulcrum (balance point) for the distribution. (Assuming that each score has equal weight, The deviations of scores above the mean must equal the deviation of scores below the mean for the distribution to balance.)
Deviant scores would effect the median the second most and have no effect on the mode.
I hope this helps. Thanks for asking.
