Accuracy and precision

26 to calculate the actual volumes delivered. Error percent analysis was then utilized to deduce the deviation from the accurate volumes. The three different sizes of pipettes used were Epprendorf 10, 100 and 1000 L. The results entailed a higher accuracy in delivering the large volumes, compared to the small volumes, within the same pipette. In addition, the medium sized pipette (10-100L) was the most accurate in delivering the targeted volumes. ϖ

Using three different sorts of glassware is ideal because it allows three different levels of precision and accuracy, therefore giving a more consistent result. In addition, doing three trials for both the density and boiling point is key because the more trials performed, the more consistent the results will be. For instance, if there were fewer trials

methods I used to keep my controlled variable of the substrate I used was to maintain the consistency of its temperature at room temperature and its amount at two milliliters for every trial. Although, regardless of the precision that I may have attempted to maintain the overall accuracy of my measurements, there may have been some factors that contribute the inaccuracy of my experimental results. These factors include the set amount of the substrate and enzyme solution used for every trial to stimulate

sentiment of movie reviews which uses a chi-squared feature selection mechanism for training. I show that machine learning algorithms such as Naive Bayes and Maximum Entropy can achieve competitive accuracy when trained using features and the publicly available dataset. It analyse accuracy, precision and recall of machine learning classification mechanisms with chi-squared feature selection technique and plot the relationship between number of

The present study was aimed at the analytical method development and validation for estimation of Aminexil and Minoxidil in Topical Solution. The analytical method validation for assay method using HPLC for Aminexil and Minoxidil Topical solution was carried out. Aminexil and Minoxidil are used in the treatment of alopecia. 5.1 Identification Fourier- Transform Infra Red Spectroscopy (FTIR) The presence of characteristic peaks associated with specific structural characteristics of the dug molecule

scaling factor is constant during the computation without externally reconfigured. As a result, the precision (least represent able value of the unit in the last place, for a fixed-point number system cannot be improved without sacrificing its represent able value range. Floating-point representation on the other hand provides not only the ability for wide dynamic range support, but also high precision for small values. A typical floating-point number is represented in four components, and its value

guide to give Joseph Jerdee feedback on his research plan. It will review clarity, accuracy, precision, relevance, depth, breadth, logic, significance and the fairness of the research plan. Clarity Joseph, the essay clearly states what the research intends to accomplish. Further, it gives good foundational information on what workplace bullying means and demonstrates that it affects both males and females. Accuracy The claims that are made in the essay about the types of bullying are supported by

The hypothesis is that very little amount of of HCI is needed to neutralize NaCl. This would need to be tested through this lab, and will be confirmed through the different series of trials. Throughout this we also checked our results and see our accuracy through the scientific process. First in the procedures of this experiment, is we had to neutralize the unknown substance. We had a beaker filled with 50 mL of sodium-hydroxide (NaOH) and buret full with 20 mL of hydrochloride (HCl), Figures 2

The accuracy of a person can be improved by playing video games that involves shooting and aiming at other objects. Shooting in a game is similar to shooting or throwing objects in real life. It takes predictions and precision. Not only in video games, but accuracy is a very important key factor in many sports as well. For example, soccer requires aiming the ball at a certain angle or direction to pass it to another player. (Frankl, 2000) This compares to the weapon shooting a bullet at a certain

Research fitness Methods task 1 Differences in methods of research Qualitative: Qualitative research is mainly informal to participate in and the outcome changes with the individual’s opinions and feelings. It includes inductive methods, this could be from the participant feelings changing at a later date or their hypothesis could change over time. Qualitative research is normally conducted by words and is more to do with literature such as what and why something has happened; this research is
