# Advanced Tasks¶

Finally, let’s consider more intricate questions about our data set.

## Tasks¶

- Calculate the differences in air temperature from one hour to the next.
- Find the biggest rise/ drop in temperature over an hour and when they happened.
- Extrapolate daily statistics for all columns from the hourly ones.
- Come up with a metric for a “nice day” and an “awful day”.
What were the most
*nice*or*awful*days in your location? **High difficulty!**Find out what the most common wind directions in your location are. Note that wind directions can be rather fuzzy values, so you might want to come with a better metric here than simply calculating the most common value. They are given in increments of 10Â°. Be aware, the wind direction wraps around after`350`

to`0`

after the adaptations we made when cleaning the data. The approach needed here is called a*circular mean*, which is somewhat tricky to understand and compute. But maybe someone knows a good approachâ€¦
