Calculating the height was the simplest part of this investigation, first the tangent theta ratio, followed by eliminating the adjacent value from the equation, leaving us with the opposite value then averaging all the trails to come to a final height. ? Diagram: Calculations: To get our results we were required to grab all the trails and get an ideal average. Here’s a diagram of what we had done: (Trail 1+Trail 2+Trail 3+Trail 4) ? 4 = 17. 74 In other words; (The sum of all trials (70. 96)) ? (The number of Trials (4)) = (The Average (17. 74))
State the conclusions that you reached about the height of the school. As a result of our accurate and correct use of the clinometer and the meter wheel, along with our high knowledge of the application of trigonometry, we were able to get a final answer for the height of our school. After analyzing all our results, I can conclude that the total height of the school is 17. 74m/1774cm. ? Did your conclusion make sense in the context of the problem? Explain why you consider your results to be reasonable or why you consider them to be unreasonable.
For our investigation, the task that we were assigned was to find the height of the school. However, this questions clears asks whether my conclusion makes sense in the context of the problem, which it clearly does to a very deep extent, but it also asks whether my results were reasonable. It took me a while to finally come to an answer to this question, my results are accurate up to a certain extent, they can be used as an estimate, but not as a precise exact point. This data is reasonable but up to a certain extent.
Bullying in the Schools
Bullying and intimidation are a major social problem in many cultures. Since it is widely considered immature and mean to perpetrate violent or threatening acts, it is not surprising that incidents of bullying are usually found among young people where they gather to socialize. Schools are a hotbed of bullying activity, and many children are victimized. Bullying has two key components: repeated ...
Yet, in terms of reasonability, various factors influence whether a particular adjustment is considered reasonable. The test of what is reasonable is ultimately an objective test and not simply a matter of what you may personally think is reasonable. So it is for my awesome teacher to decide whether my results are reasonable according to what she/he personally thinks is reasonable. Discuss the accuracy of your findings. Include comments on how confidant you can be that your findings are accurate and why you can or cannot be confident. Your response to these questions is very important.
High levels can only be achieved if you address accuracy in detail. Mathematical analysis will gain more credit then discussion. Bellow are some suggested ideas that you might like to consider. As I have mentioned previously in the reflection about reasonability. I think that my results cannot be considered accurate, yet, there was no ideal measurement to compare my results to. In other words, if there was an accurate measurement of the building in millimeters, that would be considered accurate. But to generalize my results were not accurate.
There are certain procedures that can take place to make the results more accurate, for example the meter wheel not being in millimeter. Height of the person taking the angle of measurement I think the height of the person taking the angle of measurement using the clinometer is very interesting. The height factor doesn’t affect whether or not our accuracy is rational however, it just affects increases/decreases the angle depending on the height of the observer. In conclusion, the height of the person does not affect the accuracy as it is added in later and does not affect our final result.
Percentage Error Unfortunately, since there wasn’t a specific measurement for us to be able to calculate the error and find whether or not our calculations/accuracy were clear. ? What if your angle measurements were 1 degree off course? The result of this would indeed be quite simple. As seen in my data, a small different in data can make a significant difference. But to justify it that tad bit more, a small error of 1 degree could do so much of a difference as listed bellow. If you swipe through my data and add/remove a degree there would be a significant 13% to 4. 8% error, averaging to either a negative or positive 8. 39% error. So lets say Shanthanu isn’t as stable at holding the clinometer and was nervous there would be an at least 8. 39% error in our calculations, if not more. How to improve getting a more “accurate” result of the height of the highest point in our school. •Using a millimeter measuring tape to get an accurate reading, instead of using a trundle-wheel because trundle-wheel only give measurements in meters and centimeter, but not millimeters.

Sometimes the reading can be more than 1cm e. g. 1cm and 4mm. •The horizontal distance should be measured from the tips of the clinometer to the pole, instead of measuring from the body to the pole. This method is used because that is where you start to measure the angle. •The clinometer used, gives angle to the nearest 10 degrees, but it would be more accurate to use a clinometer that gives angle in every 1 degree. It would not be accurate if the angle is given to the nearest degree, what if the angle is 55. 868492543, it would increase the
