...The First and Second Derivatives The Meaning of the First Derivative At the end of the last lecture, we knew how to differentiate any polynomial function. Polynomial functions are the first functions we studied for which we did not talk about the shape of their graphs in detail. To rectify this situation, in today’s lecture, we are going to formally discuss the information that the first and second derivatives give us about the shape of the graph of a function. The first derivative of the function f (x), which we write as f (x) or as df , is the slope of the tangent line dx to the function at the point x. To put this in non-graphical terms, the first derivative tells us how whether a function is increasing or decreasing, and by how much it is increasing or decreasing. This information is reflected in the graph of a function by the slope of the tangent line to a point on the graph, which is sometimes describe as the slope of the function. Positive slope tells us that, as x increases, f (x) also increases. Negative slope tells us that, as x increases, f (x) decreases. Zero slope does not tell us anything in particular: the function may be increasing, decreasing, or at a local maximum or a local minimum at that point. Writing this information in terms of derivatives, we see that: • if • if df dx (p) df dx (p) > 0, then f (x) is an increasing function at x = p. < 0, then f (x) is a decreasing function at x = p. • if df (p) = 0, then x = p is called a critical point of f (x), and...

One experimental group and one control group are administered the pretest and the other groups are not, thereby allowing the effects of the pretest measure and intervention to be segregated. In this study there were two groups who were studied: a group who studies alone and a group who studies with a group, this design is a combination of pretest and post test controlled group design, and the post test only controlled group design, in addition to the basic pretest/treat/posttest design three additional test, one without treatment, one without pretest, and one without both pretest and treatment were considered. For a reliable result several sets of four tests were applied and the means used. The various combinations of tested and untested groups with treatment and controlled groups allow the researchers to ensure that confounding variables and extraneous factors have not influenced the results. | |Pre-test |Treatment |Post test | |Experimental with pre-test |O1 |X |O2 | |Controlled with pretest |O1 | |O2 | |Experimental without pretest | |X |O2 | |Controlled without pretest | | |O2 | Legends: O1 with pretest O2 with posttest X with treatment Sampling Design ...

...Statement Which of the leading brand paper towels is more absorbent; Brawny, Bounty, Sparkle, or Scott? Relevance of Testable Question The relevance of this test question is to determine which brand of leading paper towels is the best most absorbent. Consumers want to use the product that is most effective at meeting their needs. A more expensive product may actually be more cost effective if you can use less of it than a brand that costs less. Literature Review Many experiments have been conducted to test the strength and absorbency of paper towels. While the steps of the experiment vary from test to test, all of experiments are testing the same two factors; how much water can each paper towel brand absorb and how strong are each of the paper towels. Below I have reviewed the process and results from three experiments that are similar to the one I will be using. In the first experiment, the tester uses five brands of paper towels to test for absorbency, using paper towels of the same size to ensure the accuracy of the results. He draws a two inch circle in the center of a sheet of paper towel from each brand represented and placing the paper towel in an embroidery hoop to maintain stability. He then drops fifteen drops of water into the center of the circle draw on the paper towel, repeating the process for each brand, and measures the amount of time it takes the paper towel to wick the moisture outside of the circle. This test concludes that Bounty has the greatest...

Note the comments along the left side of the paper that point out some of the expectations of the assignment. Abstract Assessment tools are used in classrooms, by teachers, to help them learn the many student differences. It is important for teachers to discover the different interests, ability/intellectual levels, achievement levels, and personality types of students so that they can effectively instruct students accordingly. Some assessment tools (tests) that have been found to help teachers discover these differences are Student Interest Survey for Career Clusters, Brigance Early Childhood Screen II K & 1, Woodcock-Johnson Tests of Cognitive Abilities, Kaufman Test of Educational Achievement, TerraNova/Cat 6 Test, and Millon Adolescent Personality Inventory. Interests 1. The Student Interest Survey for Career Clusters is a survey that is used for those exploring careers, or can be used by students for educational purposes only. The survey assesses students on their interests by having them answer questions by circling any and all of the given choices that best describe the student. This survey is fairly extensive, as the same 3 questions are asked 16 different times, but the list of answer choices...

...The Paper Towel Experiment. I remember watching certain television commercials when I was kid about the absorbency and strength of paper towels. They seemed to always focus on people trying to wipe up large amounts of water and most of being dumped onto the floor or wet paper towels being stretched out and weight being applied and falling through immediately. Ultimately it was the thickest and newest paper towel that wiped up all the water without spilling any and held the weight. Even as a child I felt this was completely staged and new that major parts of the research was not shown. As an adult, I just choose what I feel is a reasonable brand and wipe away at home without any thought about the value or absorbency of what I am using. With this thought in mind I decided to test four different brands of paper towels to see which one was the most absorbent. I would test the hypothesis that a thicker and coarser paper towel did in fact absorb more water. I first looked to some previous tests to see what steps they took in their testing. The first test I found dipped the paper towels into water and squeezed the towels into a glass (Penzo, nd). While this test seemed to be a good ideal, I felt for the purpose of my test I wanted to find how much water the towel held, not how much I could squeeze out of it. I also found a test that used weight as the measure of absorbency. Consumer Reports weighed each dry towel, wet them, strained them across a pan to remove excess...

... To write a good informative paper, writers need to have three basic criteria in their paper: examples, statistics, and credibility. Right now the big concern in the education system and amongst school administrators deals with the issue of standardized testing. In Don W. Hooper’s 2001 paper on “Accountability for Student Success” published by the American Association of School Administrators, he states that if planned properly the accountability system can greatly improve education. Later in time Childhood Education published Bobbie A. Solley’s 2007 paper “On Standardized Testing: An ACEI Position Paper” which states that the test only focus on what they need to know for the government test instead of actually learning critical thinking and problem solving. Hooper and Solley explain their viewpoints on standardized testing and whether or not it has positive or negative effects on students learning ability. The first type of criteria is examples, which helps with showing that the writer knows what he, or she is talking about. This is important because with evidence the reader knows that some of the paper is actually true and not bias information. In Hooper’s paper he claims schools would fail if they did not have standardized tests. In his second paragraph Hooper gives two scenarios between two different students. The first student is in a relaxed environment were they do not really know the objective, but as long as they pass the test made by the teachers, it really...

ZILIAK University of Iowa Suggestions by two anonymous and patient referees greatly improved the paper. Our thanks also to seminars at Clark, Iowa State, Harvard, Houston, Indiana, and Kansas State universities, at Williatns College, and at the universities of Virginia and Iowa. A colleague at Iowa, Calvin Siehert, was materially helpful. T cant for science or policy and yet be insignificant statistically, ignored by the less thoughtful researchers. In the 1930s Jerzy Neyman and Egon S. Pearson, and then more explicitly Abraham Wald, argued that actual investigations should depend on substantive not merely statistical significance. In 1933 Neyman and Pearson wrote of type I and type II errors: HE IDEA OF Statistical significance is old, as old as Cicero writing on forecasts (Cicero, De Divinatione, 1. xiii. 23). In 1773 Laplace used it to test whether comets came from outside the solar system (Elizabeth Scott 1953, p. 20). The first use of the very word "significance" in a statistical context seems to be John Venn's, in 1888, speaking of differences expressed in units of probable error; Is it more serious to convict an innocent man or to acquit a guilty? That will depend on the consequences of the error; is the punishment death or fine; what is the danger to the community of released...

...well in time. Avoid thinking about what will be asked in the test paper. 3. Relax and don’t think about the exam. Take deep breaths and relax your hands by stretching. Perform some religious ‘Mantra’ if you have faith in religion or at least to be away from the exam anxiety. I used to speak ‘Navkar Mantra’ which is the most powerful mantra for the Jains. 4. When the test papers are being distributed maintain cool and calm position without getting nervous or anxious. 5. Read all instructions of the test paper carefully before starting any answer. 6. Read entire question paper before starting any answer. While you read the questions also judge the question paper in terms of length, difficulty level, type of questions etc. 7. While reading all questions analyse the type of test paper in terms of essay type questions, short-notes, fill in the blanks, true-false, multiple choice questions, reading comprehension, charts etc. 8. Pay attention to the total number of questions and the amount of time which will be required to complete the same. 9. Read directions for all questions and understand what are the optional questions, if any. One of the biggest causes of loss of marks is not reading instructions or not interpreting the instructions correctly. Pay special attention to words like ‘and’, ‘or’ etc. to understand the options. Many students have wrong habit of staring the answers without complete reading of question paper. 10. If your supervisor...

...Guide to preparing for examinations Nitin D Parekh, CA, CFA, MBA (IIM, A) CFO, Cadila Healthcare Ltd The preparation aspects for examinations can be divided into four sections like Substantive Preparation, Material Preparation, Physical Preparation and Mental Preparation. Substantive preparation refers to learning the material which is the subject matter of the exam. Material preparation refers to the physical items to be taken for the exam. Physical preparation refers to specific care about food, sleep and rest. Mental preparation refers to the attitude and self responsibility, avoidance of tension and stress and being motivated and charged to take up the exam. Substantive Preparation for examinations: 1. What to read?: There is so much to read on any subject like textbooks, study guides, reference books, suggested answers etc. Read all text books and prescribed reading. 2. How to read? How to read addresses issues of methodology of reading and various reading practices. One technique is that of faster reading by not reading word-to-word and not going for re-reading called regression. Faster reading saves a lot of time. Amongst many techniques aimed at better reading, SQ3R is one of the most powerful techniques. This technique is very effectively used by me from 12th standard to Chartered Accountant, IIM MBA and CFA course. This technique is the basic foundation of my academic success leading to consistent rank holding career and...

From the beginning, I did not approve of this website being valid, just based upon looks and as the old saying says “don’t judge a book by its cover”. As the test came to a close it gave me a type of ISFP: Introvert (11%), Sensing (12%), Feeling (25%), and Perceiving (11%). Including those results, it also said that I have a slight preference of Introversion over Extraversion, Sensing over Intuition, Perceiving over Judging and a moderate preference of Feeling over Thinking. The second time I took the test it gave me different results. INFJ: Intorvert (22%), Intuitive (12%). Feeling (38%), and Judging (1%).

...joined monomers. A chemical reaction links monomers together occurs and releases a water molecule, this is called dehydration synthesis. Hydrolysis separates polymers into monomers by using water to break bonds. Organic catalysts called enzymes are proteins that increase the speed of a chemical reaction. In the lab we used Biuret reagent to test for proteins, iodine solution to test for starch, paper to test for lipids. In the first lab, we tested for the presence of proteins in samples by using blue solution called Biuret reagent, which changes to purple when a protein is present and pinkish-purple for peptides. First test tubes were marked at 1cm and then filled to the mark with water, albumin, pepsin, and starch. Next, five drops of Biuret reagent was added to the sample, covered with Parafilm, and swirled to mix. The water remained clear, indicating the sample lacked the presence of proteins, and thus was our negative control. The albumin sample observed changed to an orange-purple color, indicating the presence of protein. The peptin sample changed to a pink-purple hue, testing positive for presence of peptides. The starch sample test tube turned opaque, indicating starch is not a protein. The results of the experiment were in line with my predictions. Although I knew that starch and water would lack protein I was unsure about the albumin and pepsin. Next, we tested for the presence of starch, the complex carbohydrate called a polysaccharide, composed of glucose. To...

...can be an important tool for practitioners in an increasingly complex accounting and business environment. This guide was developed to introduce students to the world of academic research. It is not intended for PhD students or others who wish to perform academic research. Instead, the guide should make published academic research more accessible and less intimidating so that future practitioners will be able to read empirical research and profitably apply the relevant findings. The guide begins by examining the importance of academic research for practitioners in accounting and next reviews the basics of the research process. With that background in place, we then give some guidelines and helpful hints for reading and evaluating academic papers. This guide has been used for several years to introduce master’s degree students to academic literature in an accounting theory class. After reading this guide and seeing a demonstration presentation by the professor, students have been able to successfully read and discuss research findings. Key words: Understanding empirical research, supplemental readings, importance of academic research, incorporating academic research in classroom 25 26 Gordon and Porter INTRODUCTION here has long been a communication gap between the work of academic researchers and that of practicing accountants (for example, see Sterling 1973 and Zeff 2003).
