Business and Analysis- design an experiment on starbucks - Research Paper Example Company managers with this orientation strive to make their products the best and for continuous improvement. An experiment, specifically a blind two-group experimental taste test, will be conducted to find out whose latte has superior taste. The research questions are: 1. Does a Starbucks latte taste better than a McDonald latte? 2. Does a Starbucks latte taste better than a Dunkin Donuts latte? The taste test is an example of a sensory test, in which the instruments for investigation are the senses themselves (Liedtke, et al., 2005). Many such tests have been conducted. Some examples are: 1. Gunnarsdottir and Thorsdittor’s (2010) study on the effect of food packaging on the perceived taste of healthy food by children; 2. Urdan and Urdan’s (2001) experimental analysis on the effect of brand name and taste on consumers’ buying intentions; 3. Studies that assess the taste and off-taste in drinking water by using quantitative taste and odor measurements compared wi th threshold numbers to evaluate compliance with government regulations (DWI, 2002); and 4. A comparison of taste test ratings after repeated consumption of different strengths of iced tea (Vickers and Holton, 1998). The experiment will involve a blind two-group experimental design, like those used for clinical drug trials. ... Ha: A Starbucks latte tastes better than a Dunkin Donuts latte. Method Participants Though Starbucks has long insisted that it does not market to children, the young population is often seen drinking their beverages (Linn, 2007). Stratified, quota sampling will be employed. There will be six sets of sixty participants each, totaling 360 participants, stratified by age (11-19; 20-29; 30-39; 40-49; 50-59; 60 and up), where each set will have 30 males and 30 females, to control for age and sex, factors for which taste norms have not been determined (Moretz, 2006). Participants will be randomly assigned to a control group or intervention group by computer-generated randomization schedule, where each group will equal thirty participants, with equal numbers of male and female participants and stratified by age. This process is blinded, so that participants will not know their group assignment. Participants will be recruited through advertisements in the newspapers. They will be informed of their full rights and compensation and will be asked to sign consent forms. Research ethics shall be strictly followed. Interventions The control group will be given three cups (fifteen ounces each) of Starbucks latte. The intervention group will be given one cup (fifteen ounces) each of a Starbucks, McDonalds, and Dunkin Donuts latte. Administration of cups will be rotated. Both groups will be asked to rate each cup on a five-point scale (very good, good, neutral, bad, very bad). Both descriptive and inferential statistics will be employed upon analysis of results. Variables and Controls The dependent variable is the perception/measurement of taste of the lattes. The independent variable is the brand of latte, i.e. Starbucks, McDonald’s, and Dunkin

Single Slit Diffraction Pattern of Light :: Mathematics Math

Missing Figures SINGLE SLIT DIFFRACTION PATTERN OF LIGHT The diffraction pattern observed with light and a small slit comes up in about every high school and first year university general physics class. The intention of this paper is to explain this pattern at the academic level mentioned above. Light is interesting and mysterious because it consists of both a beam of particles, and of waves in motion. WAVE PARTICLE DUALITY: All carriers of energy and momentum, such as light and electrons, propagate like a wave and exchange energy like a particle. It wasn't until the 19th century that convincing evidence was found showing that light behaves like waves. Before reading on, you may wish to review some wave terminology. The key to understanding why light behaves like waves is in INTERFERENCE and DIFFRACTION. Interference and Diffraction are the phenomena that distinguish waves from particles: waves interfere and diffract, particles do not. Light bends around obstacles like waves do, and it is this bending which causes the single slit diffraction pattern. Some assumptions must be made for this description of the single slit diffraction pattern: * The slit size is small, relative to the wavelength of light. * The screen is far away. * Cylindrical waves can be represented in 2D diagrams as cicular waves. * The intensity at any point on the screen is independent of the angle made between the ray to the screen and the normal line between the slit and the screen (this angle is called T below). This is possible because the slit is narrow. point1 Consider a slit of width a, light of wavelength l, and a smaller than l. When the light encounters the slit, the pattern of the resulting wave can be calculated by treating each point in the aperature as a point source from which new waves spread out. pointb Let L represent the distance between the slit and the screen. Let T represent the angle between the wave ray to a point on the screen and the normal line between the slit and the screen. point2 The top part of the figure to the left is an imitation of a single slit diffraction pattern which may be observed on the screen (there would really be more blending between the bright and dark bands, see a real diffraction pattern at the top of this page). Below the pattern is an intensity bar graph showing the intensity of the light in the diffraction pattern as a function of sin T.

18th Century Swimwear During the 18th century, spas where men and women engaged in public bathing began appearing in France and England. Men and women still bathed infrequently for recreation and it was considered as therapy. Modesty was of prime importance with style not much of a consideration in those days. The first suits were far from practical or comfortable; ladies went as far as to sewing lead weights into the hem of the bathing gown to prevent the dress from floating up and exposing their legs.With the introduction of railroads, ocean-side beaches became popular for sunny ecreations and a need to wear bathing suits was felt to protect the skin from the harsh sun and being modest and strongly against any skin show. This 1797 Gallery of Fashion print shows two ladies protected by face-shading bonnets, shawls and gloves as they 1858 Bathing Suit typically worn by the French and English. Early 19th Century Swimwear Even though the 19th century Swimwear was not very high fashion and stylish for the masses a strong need was felt for a fashionable outfit for swimming or Sea Bathing.This is because Sea Bathing was considered as a recreational activity which was only taken up by the wealthy. The Activity itself was considered fashionable. Along with this new outdoor pastime came the need for a stylish garment for the privileged lady of fashion. Here we will follow the path of the fashionable bathing suit, which began long before the modern day bikini.

Late 19th Century Swimwear The swimsuits consisted of bloomers and black stockings.By 1855, drawers were added to prevent the problem of exposure. Women still refrained from swimming too much; the prevailing attitude of the day was that it was mainly a male prerogative. The â€Å"Princess† cut was introduced, consisting of a blouse and trousers in one piece. The skirts were replaced with cotton-like trousers. There was also a separate skirt that fell below the knee and buttoned at the waist to conceal the fgure. A ruffed cap or a straw hat completed the ensemble.

Counselor s Assessment - 1137 Words

In the lives of counselor’s assessment plays a great role. Assessments are what shows the counselor what it is that their client is in need of help in. Like our book states, assessment is a complex, problem solving process that allows us to collect information in order to better serve our client (Drummond, Sheperis, Jones, 2016). I was not aware of how involved counselors are in the testing process until I began this class. I now see that assessments also helps the client understand their own problems as well, it is just up to us to help them interpret the assessment. When using various assessments in counseling, we have to be aware of our clientele and culture we are working in. As counselors, we are to be conscious of controversies in assessments such as privacy invasions, bias test, and even the pressure of the assessment of the children. We are there to help alleviate and to insure these problems do not come to rise. Statistics in assessment is important because it enables us to keep track of how well or below average a student or group of students are doing. Statistics is the number report that we are able to visually see. Culturally, we would need to be aware of the customs, traditions, and values. We need to be mindful of each student or client’s uniqueness and be sure we are equipped with the knowledge to help them through the assessment. Through the code of ethics and the legal issues we are able to follow certain standards to prevent insulting or malpractice.Show MoreRelatedMy Career As A School Counselor769 Words   |  4 Pages will be useful in my career as a school counselor.
