10/4/2011 VHS Block 2 Shoe Size and Height Questions 1. While doing this study, there could have been a couple of experimental errors. I could have accidently not produced a 100% accurate measurement for my shoe size, foot size, or height. The reasoning behind this is because since the ruler was not flexible to bend to the shape of my foot or rounded the end of my toe and heal, I had to eye ball the exact measurement. This being said, there was definitely room for some sort, although small, measurement reading error. 2. Data from teenagers would give more variable results than data collected from adults because although some may be finished, a lot of teenagers are not finished growing yet. This meaning that the variables found are not fixed because it is possible that a teenager’s foot size could still increase, or they could even possibly grow taller. This, however, is not the case for adults. 3. Foot length (in inches) x 6.54 = Height (in inches) For my own height : 9 1/8 x 6.54 = 59.68 Height by formula = 59.68 inches Actual Height = 61.5 inches This is not a more accurate correlation between foot size and height because the difference is 1.82 inches, while the difference between my actual height and the height according to the graph was only 1.5 inches. 4. Based on my observations, someone’s height can be estimated by measuring the size of his or her shoe. This estimation however, will be about 1.5-2 inches off from their height. It is a fairly close calculation, although it will almost never be exactly 100%
