Power Bands

1. I think these power bands are not very effective. I do not think they work. I think this because in the first video the showed the test to a man who didn't think it worked and he said when the man testing the bands on people knew who had the band it worked, but when he didn't know who had it, the band didn't work as well. So I honestly wouldn't think they worked. I would have to see it to believe it.
2. My hypothesis would be that with the band on people may do a little better, but not a big differece because they believe it works so their confidence goes up and they try harder without knowing it. To test this I would get 5 volenteers and test their strength by having them try to lift 175 pounds and measure how high up they lifted it, then have them put the band on and have them try to lift it again and see if it makes a difference in the height. Then to test the balance, I would do the arms out with one foot up test and see how long they stand before falling, then retest them while they are wearing the power band and compare the results. Then to test the flexability I would have the participants put one arm out straight in front of them. Then have them twist their arms and body around until they can't go any farther  and measure how far they turned. Then finally retest with them wearing the power band and measure how far they turned that time and compare the numbers. Then i would look over all my data and make my conclusion. That is my way of how to test the power bands.
3. It is necessary to look at all sides of the before forming a hypothesis and doing an investigation because if you don't get all the data about what your hypothesis is about, it will affect your hypothesis and investigation and give you wrong results because you might be missing vital information that will affect how you run your expiriment.
