take the 2 middle numbers, add them together, then divide by 2 and that number is your median.
To find the median of a set of numbers write them in order, then: * if there are an odd number of numbers then the median is the number in the middle * otherwise there are an even number of numbers and the median is the mean average of the two numbers in the middle. With 4 numbers there is an even number of numbers, so the median is the mean average of the 2nd and 3rd numbers when they are sorted into order. Example: Find median of {3, 9, 4, 5} Ordered → {3, 4, 5, 9} → median = mean_average(4, 5) = (4 + 5) ÷ 2 = 4.5

It is 4.
Put the numbers in order. The odd one in the middle is the median: 1,2,3,4,5,6,7 (4 is the median). If even numbers, it is between the two middle numbers: 1,2,3,4,5,6,7,8 (between 4 and 5 is the median).

Mean = 4 Median = 3Mode = 2 and 3Range = 6Mean = 4 Median = 3Mode = 2 and 3Range = 6Mean = 4 Median = 3Mode = 2 and 3Range = 6Mean = 4 Median = 3Mode = 2 and 3Range = 6
Use the Excel MEDIAN function. The Median is the number in the middle of a set of numbers. Half of the numbers have values greater than the median, and half have values are less. If there is an even number of numbers in the set, then MEDIAN calculates the average of the two numbers in the middle.Examples:MEDIAN of the set of numbers (1, 2, 3, 4, 5) is 3MEDIAN of the set of numbers (1, 2, 3, 4, 5, 6) is 3.5 (average of 3 and 4)

If its a odd set of numbers then the median will be (n+1/2)th term. where, n=set of numbers like 2,4,5 then the median will be (3+1/2)th term=2nd term=4. therefore the median is 4 And if its a even set of numbers like 1,4,7,9,6,8 then the median will be the (sum of mid numbers/2) 7+9/2=8 therefore the median is 8
Assuming that you want to discount luck (if not, the answer would be 1), and that the guesser always guesses the median of the remaining range, the answer would be the (ceiling of the log(base 2) of the count of numbers in the range). If the log(base 2) is an exact integer, add 1. Example 1, pick a number between 1 and 9. There are 9 numbers in the range, so the log(base2) of 9 is ~3.16. The ceiling of that is 4. Do not add 1 for a final answer of 4. The full range is 1,2,3,4,5,6,7,8,9. The median is 5 First guess is 5. Higher - 6,7,8,9 is remaining range. 7 and 8 are the median numbers Second Guess is 8. Lower - 6,7 is the remaining range. 6 and 7 are the median numbers. Third guess is 7. Lower - 6 is the remaining range. 6 is the median number Fourth guess is 6. Correct. Example 2, pick a number between 1 and 16. There are 16 numbers in the range, so the log(base 2) of 16 is 4. The ceiling of 4 is 4. Add the 1 because the Log(base 2) is an integer, for a final answer of 5. Full range is 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16. The median numbers are 8 and 9. First Guess is 9. Lower - 1,2,3,4,5,6,7,8 is the remaining range. 4 and 5 are the median numbers Second Guess is 4. Higher - 5,6,7,8 is the remaining range. 6 and 7 are the median numbers. Third Guess is 6. Higher - 7,8 is the remaining range. 7 and 8 are the median numbers. Fourth Guess is 7. Higher - 8 is the remaining range. 8 is the median. Fifth guess is 8. Correct Both of these examples show worst case scenarios. A "lucky guess" will reduce the number of guess needed, possibly all the way to 1. Note: I do realize that to a math purist, in the examples where I said that the median numbers were x and y, the correct answer is that the median number is between x and y. Since I can not guess the number between the two numbers, I am bending the definition of median to treat the two bordering numbers as the median when the strict definition would list the median as being between those two numbers.
It is the central number in the ordered set. To find the median of a list of numbers, you have to put the numbers from least to greatest and then count in an equal number from each side. For n data values, the median will be the ordinal number (n+1)/2 For even numbers of values, it is the average of the 2 middle numbers. Example : 1 2 4 4 5 6 7 7 7 the median is 5 1 2 4 4 4 5 6 7 7 7 the median is 4.5 (4 + 5) / 2
the answer is 3
