Dad Vinci explained that for a human to have perfect proportions need to follow the next criteria: the length of the outspread arms needs to be equal to the height of the man, the distance from the elbow to the tip of the hand needs to be 1/4 of the height of man, and the maximum width of the holders needs to be 1/4 of the height of the man. After going through this whole process I got into a very concise conclusion, just two people in my class have the ideal human proportions. Hungary Ramirez and Maria Smiley are the only ones who fit into the three of the statements made by Dad Vinci and Vitreous. As is shown on table #1 and table #2, Hungary Ramie’s length of the outspread arms is equal to her height; her distance from the elbow to the tip of her hand equals a 1/4 of her height, same situation occurs on Maria Smiley measurements. But on the third criteria you can see there is a difference between the maximum of their shoulders and their heights a difference of 1 CM.

Even though their measurements have a difference of one CM, we can still say their proportions are idea, since we are account the uncertainties of +/- 1. Several of my other classmates followed several criteria but at the end they didn’t fit exactly, for example as it’s shown on table #1 and table #2, Amanda Kauffmann length of the outspread arms is equal to her height, and her distance from the elbow to the tip of her hand is a 1/4 of her height as well, but when it moms to the third criteria, the maximum width of the shoulders isn’t a 1/4 of her height. The difference is about to 4 CM, which is an extremely small difference, since the maximum of her shoulders is about 39 CM and the 1/4 of her height is about 43 CM.

Evaluation: Due to the fact that the Dad Vine’s Vitamins man lab demonstrated failure on the past examinations, we can feel free to assume that many errors are shown in this experiment. The first error noticed is the fact that we measured everything with a small measuring tape instead of a big measuring tape, which didn’t help since we were lealer and bigger than the measuring tape, so we had to use two measuring tapes added together. Using a small measuring tape to find out these measurements ended being extremely inaccurate. After data collection we were not really sure if the numbers we got were real, and it probably affected a lot on the way the results came out. The lab activity validity started to be questionable now.

By the time we were looking for the four measurements needed just one group of people from the class was using a measuring tape, the rest of the class were using two small ones (so they could have the same length). The way it worked was to put one in the top of the other and then add the numbers, which was hard for the person who was measuring since he didn’t have enough hands to hold the small measuring tape in the bottom, in the middle (place in which both tapes were combined) and in the top. If one of the measuring tapes we were using (top or bottom) moved a little bit, then the whole addition will change and the final result will end being inaccurate.

A proposed solution to this error will be measure all of the quantities again with a big measuring tape, in this way, we could make sure that all of the agreements are more precise and that no movement of the person with the tape was going to affect on the validity of the research. Another error noticed is the fact that you can always make a mistake with the numbers and get confused, so maybe the numbers you got aren’t real. A great solution to this error will be measuring at least three times each of the four requirements, which at the end will give us a more specific, secure, and valid answer. If we make another two measurements and we still get different numbers, we need to keep re-making this process until we start getting the same answer over and over again after repetitive results.

Another big error was noticed on the width of the shoulders measurements specifically, since some people didn’t know from which to which point it was, so in that way some people got a very inaccurate difference between this number and the 1/4 of the height of a man. A good example that is shown is on table #1 and table #2, were Sabina Classical and Alberta Gonzalez got a lot of difference between this two measurements. Sprain’s width of the shoulders is equal to 54 CM as is shown in the first table, and the 1/4 of the height of a mans equals to 39. In the other hand, Albertson measurements also had a huge difference between them. His width of the shoulders is equal to 65, and 1/4 of his height equals to 43. 50.

After inspecting those numbers we can conclude that there is an error, since the rest of the students show on table #1 and table #2 do not have a difference higher than three CM between the numbers as both of this students had. This numbers are very inaccurate since the width of the shoulders and the 1/4 of the height are suppose to be exactly the same, and this is such a huge difference. A solution to this problem could be measuring the width of the shoulders and the 1/4 of height of this students again, if we still get such a huge difference between both numbers, then the solution could be measuring the four principles again for this two people, at least 3 or 4 times, until the numbers we get are much more accurate.

One limitation I observed was the fact that most of us, the students, are still in a transitory age, which means we are still going through the process of developing physically. Since we are not entirely developed we are not a secure resource to prove if this statement is true or false. Our legs are not entirely developed yet, either our arms or the rest of our body. Another limitation found was the fact that we tested the validity on man and women, which variance wasn’t explain on the theory. Men and women may not have the same proportions as just man. This affected the research because women composed most of the class, so there were only two men (Alberta and Luis).
