Quick answer: Median price is half are below, half are above
Average price: All sold prices are added together into a sum;
the sum is then divided by the number of houses that sold.

An answer to an earlier Trulia Thread with the same question:

The big difference between the median and mean is illustrated in a simple example:

1. Suppose 19 workers and 1 billionaire are in a room. Everyone removes all money from their pockets and puts it on a table. Each worker puts $5 on the table; the billionaire puts $1 billion there.

The total is then $1,000,000,095. If that money is divided equally among the 20 people, each gets £50,000,004.75. That amount is the average amount of money that the 20 people brought into the room.

But the median amount is $5, since one may divide the group into two groups of 10 people each, and say that everyone in the first group brought in no more than $5, and each person in the second group brought in no less than £5. In a sense, the median is the amount that the typical person brought in. By contrast, the average is not at all typical, since nobody in the room brought in an amount approximating $50,000,004.75

The median sales price is the price literally in the middle if you line up all prices from lowest to highest. So, for example, let's say you have the prices 1,1,2,2,2,3,4,5,5,6,10. If you look for the middle number in the line, that's your median. In this example, there are 11 numbers. The number right in the middle of the line is 3 (1,1,2,2,2 are to the left of this and 4,5,5,6,10 are to the right), so 3 is the median price. There's really no calculation in median price-it's just lining up the numbers and finding the middle.

With average, you add up all the numbers, divide that number by the amount of numbers in your sequence, and you get the average. In the example above, you take 1+1+2+2+2+3+4+5+5+6+10=41. Divide 41 by the amount of numbers in the sequence, which is 11 (41/11), which equals 3.73. So 3.73 is your average.

Both are measures of center. The median sales price tells you that 50% of the homes sold higher and the other 50% sold lower, like middle. One unusually high or low sale has less effect. Average price is a calculation of adding up all sales prices and dividing by number of sales. One high extremely high or low price may skew this number.

By asking your to provide you with a CMA. If you have not hired a Realtor, check the last 6 months sales at the county court house.

Best of Luck

please determine the average price between the two prices?

property 1 is 4950 000
property 2 is 60 000

Add them together to get the sum of the two numbers. To get the average divide the sum by the total number of properties - in this case there are two properties.
