The mean is one of three ways to measure central tendency in statistics. The mean refers to the numerical average of a set of numbers. Two other measures of central tendency are the median, which refers to the number that is in the middle of an ordered set of numbers, and the mode, w...
Percentages are one of several ways of describing quantities' relationships to one another. Specifying one number as a percentage of another means specifying the fraction of the second quantity the first comprises. The percentage value is the number that, divided by 100, equals that fraction. To ...
In statistics, it’s actually rare that you can calculate the population mean. That’s because asking an entirepopulationabout something is usually cost prohibitive or too time consuming. For example, one veterinary practice probably keeps weight records of all the pets that come in the door, en...
The mean, median and mode are measures of central tendency and may also be referred to collectively as types of averages. The term “mean” in the context of statistics refers specifically to the arithmetic mean since there are other types of means, such

I have a data frame with 4 variables: "position", "year start", "year finish", "year birth". I need to calculate a mean age for a person holding all position in a given year (sum of all ages in a given year over the number of ages, to be clear). ...
Just when you think you've got mean and mode conquered, along comes the grand mean. The grand mean is the mean of the means you have already recorded. It's not achieved by dividing the total number of sets, but rather the total group sets within specific data. ...
