Calculate an average or typical time. If I would just use the median (or other "normal" types of calculating an average), for example $23:59$ and $00:01$ would yield $12:00$ when it should $00:00$. Is there a better method?

Is it possible to calculate the regular average of a sequence of numbers when i dont know everything of the sequence, but just everytime i get a new number i know the total count of numbers and the average for the numbers $-1$.

for example: $2,3,10$ the average is of course: $5$

but in the last step to calculate i only have access to the previous average of $2$ and $3:2.5$ the next number: $10$ and the count of numbers: $3$

if this is possible, how?

If we have a $3\times 3$ matrix of information where the row totals describe the total goods produced by a particular company and the column totals provide the total for a particular type of good for all companies how would I create a weighted average that tells me the average percentage Good A takes up, out of all production, for all companies? Is it necessary to weigh by company if the total number of products produced is, say, $10,50$, and $20$?

Math can be intimidating and complex, but understanding averages is a great place to start. An average is a way to measure the central tendency of a set of data. It can be calculated as the mean, median, and mode of data. Understanding how to calculate an average is an important skill to have when working with data. It can be used to track progress, compare scores, and measure performance. Averages can be calculated for a wide range of data, such as grades, test scores, weights, and heights. Knowing how to calculate an average is an important skill, and can be used in a variety of real-world situations. With practice and a little bit of guidance, anyone can learn how to work with averages.
