| Raok | this is quite tricky |
| EminYus | the key word here is evolution which states that he needs some sort of history to relate to (time-series data satisfies this) |
| johntan1979 | You can't observe evolution with cross-sectional or stratified. |
| praj24 | Just think it out logically. He owns a stock, wants to see the price change throughout a time period, therefore his observations will be over a time series. |
I used your notes and passed ... highly recommended!
