If the skewness is different, then the data sets are different.Incidentally, there is one [largely obsolete] definition of skewness which is in terms of the mean and median. Under that definition, it would be impossible for two data sets to have equal means and equal medians but opposite skewness.
MEDIANUse the median to describe the middle of a set of data that does have an outlier.Advantages:• Extreme values (outliers) do not affect the median as strongly as they do the mean.• Useful when comparing sets of data.• It is unique - there is only one answer.Disadvantages:• Not as popular as mean.
Those that are statistically significant.
The two sets of digits have different place values.
There is an inverse relationship between the datasets.
No. Here's one set of data where the mean is not one of the values: a set of 250,000 numbers. 125,000 of them are "1", 125,000 are "3". The mean of this data set is "2", which is not among the data.
(10,10,30,30,30,50,50) (20,20,30,30,30,40,40) These two sets have the same mean, median and mode.
No, not all data sets have a mode but all data sets have a mean and median.
It is a positive relationship.
No, because sometimes sets of data can have different numbers and other sets of data can have modes in them.

You can have several series which results in lots of bars in sets for different values. The type of chart you have is partially depending on the data you have.

The minimum and maximum are the same. The mean, median, and mode can be different.
The two sets of digits have different place values.
