Observational error

the average weight difference is identical to that of the weight difference caused the glucose solution. Low levels of precision can be accounted for by random errors. Random errors are errors caused my unpredictable factors such as wind change or a mistake in the method. In this experiment, there are many possible sources of random errors that may have influenced the results and these may have…

scatter, and consisted of an outlier in the sample in which the ratio of NaCl: deionised water was 10:30mL. The outlier and scatter may have been due to random errors, which caused the results to be unreliable. Due to this, the raw data does not support the hypothesis. Thus, a line of best fit was drawn in order to reduce the effect of random errors, and statistically remove the outliers, to give a better representation of what the results should have been. This line of best fit suggests that…

A weakness in this experimental design is the manual dilution of the Aquasol concentrations. This is because, if a random error were to occur, and the diluted Aquasol concentration does not result in the desired concentration, the validity, reliability, and precision of the results is majorly decreased. Whereas if the Aquasol concentrations were already previously diluted in a lab by professionals, or were bought in the correct concentrations, the reliability, validity, and precision of the…

States there are approximately 7000 deaths per year related to adverse drug events (ADEs); furthermore, it is estimated that a hospitalized patient is subject to at least one medication administration error per day (Koppel, Wetterneck, & Telles, 2008; Richardson, Bromirski, & Hayden, 2012). Medications errors usually end up extending patient stays by 1.74 days and cost the health care system billions of dollars each year (Koppel et al., 2008; Van Onzenoort et al., 2008). Most ADEs occur due to…

Sources of Measurement Error Measurement is the process by where we assign value to empirical events, objects or properties, or activities according to a set of rules or standards (Cooper & Schindler, 2014). The goal of measurement is to represent the events, objects, properties, or activities with complete precision and control. Because a researcher does not have complete control, errors do occur. Measurement error is the difference between the research value assigned and the true…

There are several errors in judgment that individuals make on a day to day basis. Everyone is guilty of making these errors regardless of their background, education, and life experiences. The common errors of judgment found in humans that I chose are Snap Judgment, Projection, and Sweeping Generalizations (Bethel University, 2013). Snap Judgment is a common error that I recognize or experience probably most often. An example would be the cop shootings on “innocent citizens”. The media and…

oxygen, showing the elodea samples to have photosynthesised more than the lower light intensity trials. Trials 1 and 2 were in water bath 1 with full light intensity, whereas Trials 3 and 4 were in water bath 2, with lower light intensity. Experimental error caused the trials with the lower light intensity to be disrupted, and no data was collected for these trials on Day 8 of the experiment. Figure 5 shows the daily volume of oxygen produced by the elodea in each trial. A linear trend line was…

Human error is prevalent throughout all of life. Even when presented with the easiest of instructions, humans tend to mess it up. Though many of these mistakes come from failure or misunderstandings, there are other instances in which over-analysis comes into play. In Victor Hugo’s novel, Les Miserables, we are introduced to one such character. This man’s name was Jean Valjean. Although a former convict, Valjean was presented with an opportunity to change his life for the better. Very few…

At my practicum, there are several opportunities for a counselor to make a mistake. However, the mistakes can be easily corrected, and most of the time the person on the other end of the phone or computer will not be phased by a slip up. The forgiveness of the mess up does not make it okay, because as social workers we should strive to always provide the best services for our clients. When I think of decisions I have made that were flawed, I immediately think of a chat session I had last week…

in writing this assignment. I reviewed the essay after the first submission, I have addressed my common errors and change some wordings. At the same time, I deleted some unrelated and redundant information to my experience in my essay. After doing so, I think the essay contained less errors and more understandable than my first…
