Sales at Sullivan Realty totaled 10 homes for the month. They were as follows:
$182,900
$189,000
$160,000
$210,000
$175,000
$158,000
$99,000
$126,000
$185,000
$109,000
Calculate the mean and medium.
I came up with $159,390 for the mean, not sure if that’s right. Not sure what the median is.
Mean is average. So you add up all the numbers and divide by the number of sales:
1593900 in sales, 10 sales, = $159,390 . You are correct.
The MEDIAN is the "middle". (The line in the middle of the road is often called the median as well).
Line up the numbers from smallest to largest, and the one in the "middle" is the median.
1. 99000
2. 109000
3. 126000
4. 158000
5. 160000 -> middle number
6. 175000 -> middle number
7. 182900
8. 185000
9. 189000
10. 210000
When you have an even number of entries,t ake the average of the 2 middle.
160000+175000 = 335,000 / 2 = $167500
Good luck!
