Uncertainty reduction theory This theory comes to explain the uncertainty among people who communicate with each other and how different types of communication will help to reduce the uncertainty. As a starting point‚ the developers of this theory (Charles Berger and Richard Calabrese) stated that uncertainty is an unpleasant feeling‚ which people prefer to avoid as much as they can. Every person has been confronted with the feeling of uncertainty‚ rather if it was when arriving to new a destination

In The Great Influenza Barry contrasts certainty and uncertainty so that there is an understanding that scientific research is in fact a pioneering effort through effective abstract language‚ romanticized syllogism‚ and strong metaphors. Firstly‚ the author points out the obvious knowledge of uncertainty and certainty where “certainty creates strength” while “uncertainty creates weakness by using antithesis. That’s general knowledge that most people - myself included- involved scientist as well

Evaluation of procedures: |Precision |The precision of each of the measurements you made is indicated by the % uncertainty calculated. | |Accuracy |The accuracy of an overall result (concentration of acid) means how close it is to the ‘true’ value. | | |It is possible to make very precise measurements but still end up with an inaccurate result because of a weakness | |

balanced equation‚ but the amount of catalyst matched the original value when uncertainty is taken into account. The percent yields for the reactants in the equation are very far from 100% yield. In the case of water‚ the percent yield came out to be meaning there were at least 2 times to 4 times more water than there should be. The percent yield of oxygen came out to be ‚ around 2%‚ maybe higher considering uncertainty of what amount of oxygen there was suppose to be. The reaction was incomplete

Hofstede ’s Dimensions. Brazil ’s highest Hofstede Dimension is Uncertainty Avoidance (UAI) is 76‚ indicating the society’s low level of tolerance for uncertainty. In an effort to minimize or reduce this level of uncertainty‚ strict rules‚ laws‚ policies‚ and regulations are adopted and implemented. The ultimate goal of this population is to control everything in order to eliminate or avoid the unexpected. As a result of this high Uncertainty Avoidance characteristic‚ the society does not readily accept

Solid Mechanics Lab Report Experiment to determine the Young’s modulus of an aluminium cantilever beam and the uncertainties in its measurement 1. Abstarct: The young’s modulus E‚ is a measure of the stiffness and is therefore one of the most important properties in engineering design. It is a materials ratio between stress and strain: E=σε Young’s modulus is a unique value for each material and indicates the strength of that material as well as how it will deform when a load is applied.

Boris Tjhia 11PDe Physics IA Factors affecting the time period of a pendulum. Research question: How does the length of a pendulum affect its time period? The independent variable is the length. The dependent variable is the time. Controlled variable is the mass of the pendulum bob. Formula for 1 period of oscillation of a pendulum of a certain length is T=2π √lg Where l is length and g is gravity (9.81 ms-2) T2= 4π2 lg T2= 4π2g l Hypothesis: The longer the length
