            No, it wasn’t wrong because it didn’t specify which average was meant. If it was “arithmetic average”, it would be wrong.

              It would still be right. The test results are reported on a normalized curve so all measures of central tendency are all equal.

                “No, it’s green”
                “If you don’t specify then the statement needs to hold for all balls to be correct.”

                And by the way: for the given plot, it is correct for all averages

          It’s absolutely not. Median is a value in the middle of a sorted set and average is, well, average. In the set of 1, 7, 10: 7 is median and 6 is average.

            Idk man looking up a definition for “average” is like

            1. a number expressing the central or typical value in a set of data, in particular the mode, median, or (most commonly) the mean, which is calculated by dividing the sum of the values in the set by their number.

            and

            1. Any measure of central tendency, especially any mean, the median, or the mode. [from c. 1735]

            and

            1 a : a single value (such as a mean, mode, or median) that summarizes or represents the general significance of a set of unequal values

            doesn’t look like that dude’s using the word “wrong” to me, a lotta people and mathematicians definitely recall using “average” meaning median

              What’s ironic here is your comment, lol. “Average” can and is absolutely used to say mean or median or any other average that is representative based on the dataset in question. When you ask a statistician to calculate an average of a dataset they probably won’t just go calculate the mean, they’ll think about which value is most appropriate in context.

        True, but those who know what “median” means probably also know what a “quartile” means, so if I used “median” it would’ve made my comment less of an “obvious, duh!” thing and spoil the unstated point I’m making as well as the joke.

        Best leave the mathematical incorrectness there to preserve the feeling of obviousness.

          Yes. In a normal, or Gaussian, distribution, the data is symmetrically distributed around the mean and thus mean (average value), mode (most frequent value) and median (middle value) all fall on the same point, which is the highest point of the curve.

          Consider an exam in which there are two questions: one very easy and one very hard. You’ll get a supermajority of people who answer the first question and two tiny tails - zero correct, two correct - such that the mode is very high and the outlayer groups are very small.

          Then well over half the people are in the median and mean.

      One could construct tests where this isn’t a given. Create an exam with one really easy question and one really hard question. You’ll end up with a huge spike in the center and two tiny tails. The top quintile of correct answers (<=1.6 correct answers) will be vanishingly small.

      My state’a standardized test says kids are “at risk” if they aren’t in the top 40% of the test. The top 50% could all be traditional “a-b” students. But because they weren’t in the top 80% of a-b students they are at risk for failing academically… It’s so asinine and disheartening. The last half of the year is devoted to this idiotic test. Kids could be learning stuff that will enrich themselves… Instead they are learnig how to take a test better.
