Quantitative Research i. Rigor‚ in Quantitative studies is the act of striving for excellence in research‚ and it requires discipline‚ adherence to detail ‚ and strict accuracy. It has measuring tools‚ a representative sample and a tight controlled study design. ii. To critique the rigor of a Quantitative study‚ the reasoning and the precision used in conducting the study must be examined‚ all of which includes logical reasoning related to deducting and inductive reasoning. iii. In Quantitative‚ rigor

Chapter One: Chemistry and Measurements Describe the “scientific method” in terms of hypothesis‚ experiment‚ theory‚ and law. • The scientific method begins with observation (a woodpecker is make a hole in a tree). • Followed by hypothesis (because the tree has termites) • Followed by experiment (a collection of woodpeckers is observed in a setting in which trees have no termites). • Leading to a refined hypothesis and further experiment to a possible theory (woodpeckers only

There is a large debate on what style of rifle to use for long range‚ competition‚ and hunting shooting. Some of the older generations say‚ “ A rifle is one where you have to pull the bolt back every time you pull the trigger” (Nichols‚ Jerry). I believe a rifle

the spinach extract at 18oC should have a faster rate of reaction than the 5oC extract because higher temperature allows substrates to move more rapidly hence increases the chance of collision with the enzymes. Moreover‚ the experiment was low in accuracy as the class average varied significantly to the individual results. Therefore‚ random and systematic errors may have affected the reliability and validity of the outcome. Random errors that may have caused the result to be imprecise include: the

Introduction to Measurements & Error Analysis The Uncertainty of Measurements Some numerical statements are exact: Mary has 3 brothers‚ and 2 + 2 = 4. However‚ all measurements have some degree of uncertainty that may come from a variety of sources. The process of evaluating this uncertainty associated with a measurement result is often called uncertainty analysis or error analysis. The complete statement of a measured value should include an estimate of the level of confidence associated

------------------------------------------------- Nov. 23‚ 2012 A skillful researcher aims to end his study with a precise and accurate result. Precision refers to the closeness of the values when some quantity is measured several times; while accuracy refers to the closeness of the values to the true value. The tool he utilizes to prevent errors in precision and accuracy is called statistics. In order to become familiar to this tactic‚ the experiment aims to help the researchers become used to the concepts

Weight of the vial‚ the cap‚ vial with cap and the vial that was induced with the factors affecting the sensitivity of the balance (e.g. moisture) were determined. As seen‚ there were significant differences on the weights though there were some errors observed. Expected results were not seen because of certain influences that somehow affected the precision and accuracy in weighing. All in

whole did not have the best precision and accuracy‚ it was mainly due to one or two groups having poor results. On a group to group basis though‚ there was very good accuracy. The results of each compound clearly identified the unknown with one of the iron compounds. There was no guessing which unknown was which compound because each experimental mass percent matched up well with the theoretical mass percent of the iron compounds. So a lot of confidence is behind the accuracy of the identification of
