I’m assuming y’all know about means. In my home school district mean, median, and mode were all taught in third or fourth grade and referenced occasionally in math classes subsequently. But I’m guessing you don’t know about types of means.
See, the mean we’re familiar with is more properly called the “arithmetic mean,” so called because it uses simple arithmetic. But there are others that show up in statistics and other scientific applications. The most common are the geometric mean, the harmonic mean, and the quadratic mean (also often called the root mean square). And all of these are based on the generalized f-mean.
