Calculating medians in statistical software such as Stata should be easy, and it usually is. When you want a row median—a median within observations across several variables of the same kind—it appears trickier. This problem is worth some discussion, not just because it arises in practice. ...
Before you can begin to understandstatistics, you need to understand mean, median, and mode. Without these three methods of calculation, it would be impossible to interpret much of the data we use in daily life. Each is used to find the statisticalmidpointin a group of numbers, but they ...
