How do you find the mean, median and mode of x, x, x, x, x+y, x+y, x+2y, x+2y, x+2y, x+2y?
Mean, median and mode all are
The data is completely symmetric as
and there are again
Further mean of
Hence, data is completely symmetric and there is no skewness.
Hence mean, median and mode all are just
Alternatively, as there are already in ascending order, there are two middle values
Further, mean is
Although for mode we have maximum frequency at two data points
