Research Question: Do we have the ideal proportion? The length of the outspread arms is equal to the height of a man The distance from the elbow to the tip of the hand is a quarter of the height of the man The maximum width of the shoulders is a quarter of the height of a man Data Collection: Raw Data: Table #1: Measure of the Outspread Arm, Height, from Elbow to the Tip of the Fingers, and Width of Shoulders (cm) (per person) Name Outspread arm /cm +/-1 Height /cm +/- 1 From the elbow to the tip of the fingers /cm +/- 1 Width of shoulders /cm +/-1 Silvana Chumaceiro 170 163 43 43 Anna Marrone 165 163 41 42 Sabrina Casilla 158 156 37 54 Alberto Gonzalez 180 174 48 65 Yanuara Ramirez 164 164 41 42 …show more content…
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 ¼ of her height is about 43 cm. Evaluation: Due to the fact that the Da Vinci’s Vitruvian 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 taller 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

Find from the “Starting” and “stopping” locations of where you are going to measure. i.e., I am going to have Charles lay down and I will measure from the bottom of his feet to the top of his head
Throughout the test the same people took the measurements each time and the same person was doing the step test. The height of the step, the length of the exercise time and the pace of the stepping were all kept monitored so they kept the same and there were no changes to the subject. For results to be valid it must be possible to replicate them and this experiment has been carried out many times before and so the results expected have been explained many times over. If the results do not replicate the expected results, then they may not be valid and effective to use in the investigation.
Doctors Craig Haney, Curtis Banks and headed by Doctor Phillip Zimbardo. This article provides in detail the initial purpose for this study, its participants, the nature of the study, the events that transpired during the experiment and of its results. With this article we are provided with a clear picture of the events that had transpired during the experiment and provides some insight into why the events may have occurred.
Circumference of head and chest is equal; head size is in better proportion to the body.
This lab could have contained errors. The errors could have happened when performing the lab. Some of the possible errors in this lab are:
There are two main errors that could happen in this lab. The first being human error when weighing the elements. This would result in more reactants which would cause more products and a misreading
The overall shape of the distribution of soldiers’ foot lengths was a symmetric unimodal with a single outlier. The center of distribution was about 26 centimeters.
Another way they have figured out is measuring the humerus. If you are a female you measure her humerus in centimeters and multiply it by 3.08 and then add 64.67. If you are a male you measure in centimeters and multiply it by 2.89 and then add
These different mistakes during the lab caused the results to change during the
Polykletios followed a ratio in his creation of Doryphoros, the head height being on one-eighth of the total height, and the forearm length being one-quarter of the body length, creating a 1:2:8 ratio for the creation of the perfect human body
The evaluation in this report showed that the equation has considered comprehensive parameters such as horizontal location and asymmetric angle. However, several parameters such as the horizontal location failed considering the anthropometric differences of the worker. The workers assumed has a similarly optimal horizontal location,
Certain areas of measurements was harder to take than other areas because of it’s angle. It was harder to take skin fold measurements on a participant who did not have much fat on their body. It was also difficult to take measurements when the participant was in multiple layers of clothes. The potential sources of error when measuring circumferences and skeletal diameters can occur if the administrator does not properly measure the specific areas. Measuring too high or too low of a certain area can skew accuracy.
In order to perform this lab, the students will require a measuring tape and calculator.
