Brief Information of the experiment:
Independent Variable: Different Wind direction (Check Photo 1 below)
1. One direction from East, South, West, North, Upward, South East (SE), South West (SW), North West (NW), and North East (NE).
2. Two different wind direction simultaneously:
Ex) From West & East (W-E), South & Upward (S-U), North East & North West (NE-NW), South East & South West (SE-SW), South East & Upward (SE-U), North West & Upward (NW-U), West & Upward (W-U), and North West & South East (NW-SE)
Photo 1: Different wind directions Dependent Variable: The performance and results of ski jumping
(Including stability of the human figure while flying)
Control Variable:
1. Same Skateboard and same human figure are used. Moreover, the pose of the ski jumper is constant as it is shown in photo 3.
2. Room temperature is 22°C ± 1°C
Room humidity is 50% ± 1%

First of all, it was able to conclude that wind going upward is the most influential wind direction to the performance and the results of ski jumping event. This is because ski jumper flies more than 92cm all the time. In addition, wind coming from South has considerable impact on the ski jumper. The reason for this is because the wind from South enables ski jumpers to fly near 90, which is far distance compared to other directions of the wind. The key point is that when these two directions combined, this provides the chance to ski jumper to fly the farthest. Evaluation: Overall observations still permit me to draw a conclusion on the effects of different wind directions on the performance and results of ski jumper. However there are certain limitations of the experiment. Generally, random
