Random error

1.1 Overview Cryptography is the science/practice of “writing in secret” (“crypto”= “secret, “graphy” = “writing”). Cryptographic functions are generally defined as algorithms or protocols, rules that govern how data is processed to turn plaintext (unencrypted data) into cipher text (encrypted data) [1]. Cryptography is a method of storing and transmitting data in a form that only those it is intended for can read and process. It is considered a science of protecting information by…

However, abilities for operating results of laboratory and imaging tests, prescribing drugs, tracking immunizations are less available (Gans, 2005). There have been a number of stratified random sampling studies across hospitals and medical centers to see how the originators of EHR adoption evolve and to allow for testing the predicting legality of the theoretical foundation (Gagnon, 2010). In every study done, there have been similar findings…

In the observer’s experience apples are less acidic then oranges and both are less acidic then lemons, and this pattern continues with sweetness. Additionally, many cellular processes are affected by the pH of the environment in which they taker place. Because fruits contain a high sugar content, it was theorized that the extracts of these fruits could be used as a source of energy for Saccharomyces cerevisiae. By measuring the rate of fermentation of the yeast given these fruit extracts, the…

randomly. More importantly, all other procedures were identical for participants in both classes except this random assignment to conditions. Next, the research design was subtle because it controlled for confounding variables carefully, such as using deception to disguise the true purpose of the study in order to reduce motivation and placebo effects, eliminating self-selection effects through random assignment, providing similar teaching facilities and classroom designs, using computers to…

via multiple cameras. Social attention features are excellent predictors of the Extraversion and Neuroticism personality traits. Results of the experiment showed that while prediction performance for both traits is affected by head pose estimation errors, the impact…

farms, and the game in general. It was more professional based then the in-game chat. People wanted to convey and convince people on how to farm, guide, and show errors in the game. They wrote well-written paragraphs that were interesting on the topic provided. Due to this, I became inspired and started to write my first guide. It had many errors and had a hard time conveying my point. Nevertheless, the community members gave me the advice needed to make my entry stronger. In the end and after…

size especially when the female and male heights are separated. This will give me a higher standard error of the mean and thus lower the accuracy of the experiment especially in relation to the entire population. Results I organised the data into three columns; male, female and all. I was then able to calculate some statistics of each in order to compare them. As I anticipated, the standard error of the mean was quite high due to the small sample size; approx. 61% (male heights), 43% (females)…

common sense. How do psychologists respond to this claim? What is it that psychologist do, as scientists, that goes beyond common sense and casual observation? Psychologists use the the concepts of hindsight bias, our tendency to perceive patterns in random events, and judgmental overconfidence to respond to those that argue that psychology is just common sense. Hindsight bias is the tendency to believe, after learning an outcome, that one would have foreseen it.…

Due to the random assignment of subjects it is assumed that the two groups are equivalent, and allow for comparison of results, in order to determine if there is a positive effect when one smiles. Between- subjects design is advantageous because it allows each individual…

In this modern age of information gathering and retrieval, the thought of how and to the extent we can store information has always been an issue of paramount concern. For while libraries, hard drives, and floppy disks served their purpose in bygone times, the amount of information we have today, along with the prodigious rate it is still growing, have made them , while not necessarily obsolete, insufficient for the task. This is why the most promising method of storage in the current time is…
