Median is the middle number. In case there are two middle numbers, you can either calculate the average for the result or mark both numbers.
20 30 40 50 median is 35 or {30;40}
20, 40, 50
The median is the 50% percentile.
30 times because it landed on heads 20 times, but he flipped the coin 50 times. 20+30=50.
No. By definition of the median, the median has 50 percent of the case below and 50 percent of the cases above. This has nothing to do with the cases being in a normal distribution.

Take your pick; 10 and 20, 10 and 30, 10 and 40, 10 and 50, 10 and 60, 10 and 70, 10 and 80, 10 and 90, 20 and 30, 20 and 50, 20 and 70, 20 and 90, 30 and 40, 30 and 50, 30 and 70, 30 and 80, 40 and 50, 40 and 70, 40 and 90, 50 and 60, 50 and 70, 50 and 80 50 and 90, 60 and 70, 70 and 80, 70 and 90, 80 and 90.
40
Let's say that this numbers are placed in order as x, y, z. So the median is y = 40, and the range is the difference between z and x. So z - x = 30. The sum is: x + y + z = 110 Substitute 40 for y, and x + 30 for z; x + 40 + (x + 30) = 110 2x + 70 = 110 subtract 70 to both sides. 2x = 40 divide by 2 to both sides; x = 20 so, z = x + 30 z = 20 + 30 = 50 Thus these numbers are 20, 40, and 50.
10, 20, 30, 40, 50, 60, and so on 10, 20, 30, 40, 50 The first ten multiples of ten are 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100. 10,20,30,40,50,60,70,80,90,100,110,120,130,140,150,160,170,180,190.........................……and keep on adding 10.
10, 20, 30, 40, 50
10 plus 20 plus 30plus 40 plus 50 equals 150 because 50 plus 40 equals 90 plus 30 =120+20= 140 then + 10 = 150
20 30 40 50 60
50% of 40= 20 25%(half of 50%)=10 5%(a 5th of 25%)=2 10%=4 20%=8 30%=12 40%=16 50%=20 (And so on...) Percents are easily understood if you know what to do to break down a problem into pieces. :]
If you're starting at zero and proceeding up, they're 10, 20, 30, 40, and 50. If you're starting at zero and proceeding down, they're -10, -20, -30, -40, and -50.
20/50 = 40/100 = 40%
10, 20, 30, 40, 50, 60, 70, 80.
They are about £20 or 30 in UK but in USA they are $40 or 50. Xxx
