Accuracy and precision

data were the main concerns in big data. An interesting point he put across was that someone stated he did not love statistics but he loved what one could do with statistics. The author emphasized that precision and accuracy were not synonymous. He said that big data allowed us to be precise. Accuracy, however, was about whether a figure had a certain relation with the reality. He also talked about the power of predictive analysis,…

Rounding Data When data is gathered and calculated, the final information presented tends to be rounded. On some occasions it may be necessary to round data, especially when rounding non-integer vales to integer values for simplicity and statistical representation. An example of this would be at the end of the calculations in sample weighting, the fractions you get are rounded to integers, since the data is based on physical objects which cannot have fractions, and so is considered extra for…

to four items at a time. Though this previous research provides a basic understanding of how much a memory of a child can withhold Burnett decided to take a step further in their research and analyze the precision of memory in this population. The null hypothesis indicates that the precision of memory stays constant throughout ages. On the other hand, the alternative hypothesis that was proposed by the researchers…

Rebels was a historical fiction novel, accuracy is very important. In order to feel the full flooding of high run emotions throughout the book, it had to feel real first. In order to fall in love with the character and hurt for the character, the reader had to first believe the character. Although the story took place in the 1700s while the book itself was written by John Jakes in 1979, I still find the historical precision of the novel well done. Due to the accuracy, there is a lot to take from…

Elements of Sculpting in the Renaissance Sculpting is a complex art form, requiring absolute precision in proportions and texture in order to make the piece believable to our eyes. Some of the greatest artists are able to turn stone into softly pressed flesh or a billowing piece of cloth. They created these pieces using refined techniques and prior knowledge. The old renaissance sculptures used accuracy, texture and previous Roman and Greek techniques, styles and concepts to make their works.…

Precision weapons have been around since the Civil War and have been evolving ever since. Ever since the development of such weapons, soldiers have been more effective in the battlefield, while also reducing collateral damage. Everyday more and more precision weapons are being made and used around the world. In today’s wars, precision weapons are a normal thing, which have made wars much cheaper and quicker. The development of precision weapons has changed the outcomes of many wars throughout…

3A.2.10 Robustness A method is robust if it is unaffected by small changes in operating conditions. To evaluate the robustness of developed analytical method few parameters were deliberately changed. The parameters included analysis at different temperatures viz. 250C and 300C, at 0.8 and 1.0 mL/min flow rate, using C18 columns from different manufacturers one from Qualisil BDS, USA (4.6 x 250 mm x5µ) and the other from LC-GC, India (4.6 x 250mm x5µ). Each of the three selected factors were…

can invariably influence the overall accuracy of the experiment. A salt bridge keeps charges from accumulating on one side or the other, thus maintaining charge neutrality. Failure to attach a salt bridge to each half cell causes the solution in the anode compartment to be positively charged and the solution in the cathode compartment would become negatively charged, because of the charge imbalance the electrode reaction would quickly come to a halt. Precision of this experiment could not be…
