Dataset:
City A: 1.0, 1.2, 1.2, 1.3, 1.5, 1.6, 2.5, 4.8, 4.9, 5.3, 7.0, 7.7
City B: 7.4, 7.5, 7.6, 7.9, 8.0, 8.2, 9.0, 9.2, 9.8, 9.9, 10.0, 11.5
Determine the median monthly rainfall for each city.
What don't you understand about this problem?
I understand but what is the number between 1.6 and 2.5
Median = middle number in order
Take the average of 1.6 and 2.5.
(1.6 + 2.5)/2 = 4.1/2 = 2.05
thank you
You're welcome.
Next time, use a calculator.
To determine the median monthly rainfall for each city, we need to find the middle value in each dataset when they are sorted in ascending order.
For City A:
1. Sort the dataset in ascending order: 1.0, 1.2, 1.2, 1.3, 1.5, 1.6, 2.5, 4.8, 4.9, 5.3, 7.0, 7.7.
2. Since the dataset has an even number of values (12), we need to find the average of the two middle values: 1.5 and 1.6.
3. Add the two middle values and divide the sum by 2: (1.5 + 1.6) / 2 = 1.55.
So, the median monthly rainfall for City A is 1.55.
For City B:
1. Sort the dataset in ascending order: 7.4, 7.5, 7.6, 7.9, 8.0, 8.2, 9.0, 9.2, 9.8, 9.9, 10.0, 11.5.
2. Since the dataset has an odd number of values (12), the middle value is the median. In this case, it is 9.0.
So, the median monthly rainfall for City B is 9.0.
