142 is the median.
Prior to the introduction of 170, the mean, median, mode and range did not exist since there were no numbers at all. Once 170 is introduced, it becomes the mean, median and mode. The range is zero.
(67,102,170,237kg) Median: (102+170)/2 = 136kg
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
196 = 142
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.
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 is used when reporting ordinal data.
No, not all data sets have a mode but all data sets have a mean and median.
The median is the midpoint of the data set. So half the observations are greater than the median and half are smaller.
