Nt1310 Unit 6 Lab Report

The potential sources of error for a skinfold measurement are the evaluator may not obtain just the adipose tissue but part of the muscle as well, which will decrease accuracy. Also, the evaluator may not obtain all of the adipose tissue present, which will decrease accuracy of measurements as

The problems we found during the lab were that the spring scales were not calibrated or they were broken. We also had some bad data on the second scale (.06, 1) it was a lot of weight compared to the mass, and you can see on the graph that it is in a weird place and not near the line of best fit. Non of those errors messed up the lab too much. Since Fg=m*g, an acceleration due to gravity (g) on earth is always 9.8m/s^2. Theory says that the more mass the more weigh.

Some ways to improve the lab are to make sure that the error sources are fixed. Next time, it should be imperative that the table being used is perfectly balanced and that the tape is not placed on the inside

During we test our Atwood’s machine, we asked to control the time between two weight to touch the ground in 2 second. However, it is really difficult to have difference time in 2 seconds in the real life ever we calculate to get the true mass of weights. There are two causes that we think may affect our margin of error which is the friction and the human benchmark. The friction always is the main issue of any experiments.

All the experiment was depending on fortune and luck and can not be successful at all because the performers do not have proper direction to perform the experiment. For the experiment, workers should have proper equipment, standardise and should have power to do work their own way. It is also concluded that the quality of production might be great in future by use the present statics and create a quality control chart and solve the problem in specific problems which effects the project. The common wisdom is that if only people did not make so many mistakes, there would not be so many problems. But even with the variation contributed by the people reduced to zero, there are still too many red

The floor is decorated with tiles that are the same length all around the room. We noticed that instead of lining up meter sticks along the wall, just measuring the tiles and multiplying how many tiles were along the wall would be a faster and more accurate way. We first had to measure the length of the tiles on the ends of the wall because they were cut off by the wall, therefore having a different length than the other tiles. The uncertainty for those were 0.5 millimeters because we only had to make one judgment since we had the meter stick up against the wall.

Lastly, the percent difference of experiments 2 and 3 was the smallest value: 32.2% Nevertheless, this is still a medium-sized value for percent difference, which was likely caused by human error in both experiments. However, this value is smaller than the others since the experimental value for the coefficient of friction for both experiments were larger than the value in experiment

And also not all variables were controlled. Finally the information is provided by the observer which could be biased o

Purpose: The purpose of this experiment is to investigate the changes in temperature one meter above the ground along an environmental gradient of one meter. The data will be take using increments of one meter from a wall. Introduction: An environmental gradient is a gradual change in abiotic factors through space (or time). Environmental gradients can be related to factors such as altitude, temperature, depth, ocean proximity and soil humidity.

More trail could have been performed to try to get more accurate data, but after sometime habitation or expectation would have occurred and the data would be affected by it. Another issue the accuracy of the measurements. It’s important to start each trail on the same point, however we did not indicate the exact starting point. This most likely didn’t cause that much of an issue, but it’s always something that can hinder the measurements accuracy. Next time it would be better to make a mark of a starting point on each of the body parts

We had been using a tape measure that had a metal loop on the bottom. We believed that the metal loop was for accessory and was not to be used to measure with. However, we learned that the bottom of the metal loop was the 0 cm mark. After learning this we had to remeasure all of our data due to this

Birthdate Relationship Compatibility: How It Works How compatible are you with the person you're with or the person you plan to be with? It would be so nice to know how well you’ll get along, regardless of the situation, or whether or not you're in the same wavelength. Well, the answer is in the stars.

The set up for the experiment can be seen in figure 2. Where the finite airfoil in figure1 is attached to a force balance that is located right below the wind tunnel. The force balance is attached directly on to the 0012 airfoil. The force balance is the instrument that was used to directly measure the lift and drag forces that were acting on the airfoil.

To put it simply, a particular theory may not be supported because the wrong measuring instrument was used (Eysenck, 1991, p.
