To find the median of the given data, we first need to list the number of days of rain in ascending order:
Days of Rain: 6, 6, 7, 7, 7, 9, 10, 10, 10, 10, 11, 12
Now, the data set has 12 entries (which is an even number). To find the median, we take the average of the 6th and 7th values in the ordered list.
The 6th and 7th values are:
- 6th value: 9
- 7th value: 10
Now, we calculate the median:
Median = (9 + 10) / 2 = 19 / 2 = 9.5
So, the median of the given data is 9.5.
