It depends on whether you mean median in terms of statistical data or the line joining a vertex of a triangle to the midpoint of the opposite side.
The Statistical Median:
If there are n observations where n is odd, then the median is the (n+1)/2 smallest observation. If n is even, then the median is the arithmetical mean of the n/2 and n/2+1 smallest observations.
The Coordinate Geometry Median:
Given triangle ABC, with A = (xa, ya), B = (xb, yb) and C = (xc, yc), the midpoint, D of BC is [(xb+xc)/2, (yb+yc)/2] and so, the equation of the median AD is
(y-ya)/(x-xa) = (2ya-yb-yc)/(2xa-xb-xc)
you just simply cut it in half and you'll have the median
The formula is: median of lognormal = exp(u)
n+1/2
If you want to get the median of numbers within the first quartile, you have to use the QUARTILE, MEDIAN and IF functions together and then enter it as an array formula. Say your values are in the cells from E2 to E27. =MEDIAN( IF( E2:E27<=QUARTILE( E2:E27,1 ), E2:E27 ) ) To enter it as an array formula, you must press Ctrl- Shift - Enter together. The formula will then appear with curly braces around it, indicating that it is an array function.

You have to use the MEDIAN and IF function together and then enter it as an array formula. Say you wanted to find the median of values in cells from E2 to E27 that were over 20, you would type this in. =MEDIAN( IF( E2:E27>20, E2:E27 ) ) To enter it as an array formula, you must press Ctrl- Shift - Enter together. The formula will then appear with curly braces around it, indicating that it is an array function.
m^2=(2b^2+2c^2-a^2)/4 where m is the median of triangle ABC.
If you will let me assume that the probability density function (pdf) is absolutely continuous over its support then the median is given as the integral from -inf to the median of the pdf over that support = 1/2.
The median is the middle number. If there is an odd number of numbers in the set, the median is the middle number, and the only way to find the missing number is if the median is the missing number. If there is an even number of numbers in the set, the median is the average of the two middle numbers, and the only way to find the missing number is if the median is one of those two numbers. If it is, you can take the median and the one of the two numbers you know. Use the formula (# +#)/2=median and solve.
