Yes it can.
When there are an even number of observations and the middle two numbers are not the same.
Median
the midpoint of the data set
it is the median
S={1,2,4,5,7}, the median is 4
That is called a median.
No, they must have a median. However, if the data set is of even order, the median may not belong to the data set. For example, the median of 1,2,3,10 is halfway between 2 and 3 or 2.5 which is not a data point.
The median in a set of data, would be the middle item of the data string... such as: 1,2,3,4,5,6,7 the Median of this set of data would be: 4
The median is the midpoint of the data set. So half the observations are greater than the median and half are smaller.

The median, by definition, tells you the "half way point" of your data. Exactly half of the observations in the dataset will be less than the median and half will be greater than the median.
The population data may be skewed and thus the mean is not a valid statistic. If mean > median, the data will be skewed to the right. If median > mean, the data is skewed to the left.
the median is the middle number in a set of data.
S={1,2,4,5,7}, the median is 4
