Transcript of The Scientific Method

Start with a question.
The Scientific Method
Would wearing socks over shoes reduce slipping/sliding??
Our theory is that wearing socks over shoes will not prevent/deter sliding. Shoes are made to have traction, right??
Our Hypothesis -
Now we need to test our hypothesis and perform the experiment.
So, that means that the person walking is attracted to the slippery ground by gravity.
Treatment Group:
this group will wear their socks over their shoes.
Control Group:
this group will wear their socks inside their shoes.
We need two groups, a control group and a treatment group. Our variable in this experiment will be the way that the participants wear their socks.
He-he! :)
Fact: Traction is the adhesive friction of an object on a surface on which it moves.
Self-rated Slipperiness*
Wearing socks over shoes is the new black, didn't you know?
Observer-rated Slipperiness*
Time to Descend Slope (in seconds)
The Law of Gravity states that
everything is attracted to each other,
and is affected by mass and distance.

The participants self-evaluated slipperiness on a five-point scale, 1 being least slippery and 5 being most slippery. Other sources of data included onlookers' evaluation of falls (on the 5-point scale), which included the severity of participant slipping, observed participant confidence; and the time taken to descend the study slope.
This experiment demonstrated both Quantitative Analysis and Qualitative Analysis well:
14 people did not wear socks and 15 people did. Wearing socks over normal footwear was shown to have a "statistically significant improvement in traction." A larger percentage of the intervention group (71%) compared to the control group (53%) appeared confident; one member of the control group fell due to improper sock placement, and this person's data was not used.
The opinion rating (using the 5-point scale) of the participants represents the Qualitative Analysis
The percentage of people that fell or had trouble with slipping in each group represents the Quantitative Analysis
30 random pedestrians, aged 18 to 70 (median age: 20), were used in this experiment. They walked downhill "on icy public footpaths at two sites in Dunedin, New Zealand." Participants wore various pairs of socks over their typical footwear.
Wearing socks over shoes appears to be a practical and inexpensive way to lower the risk of slipping on ice. It may not look trendy, but it's a creative and low-cost approach to winter safety. Never underestimate the power of socks! :)

He should have worn socks :)
Let's think about it...
