1. What is the hypothesis that will be tested in the experiment?
If the model added milk before the coffee, then she would be able to taste the difference if she added the milk after the coffee.
2. Why is it important to offer the model more than just two cups (one with the milk added first and one with the milk added second)? Explain your answer.
It is important to offer the model more than just two cups because the more the better. The more cups you have, the data would be more accurate and reproducible.
3. How many cups of coffee should the model taste? Explain your answer.
Ten cups are an ideal amount of cups to give to the model but there should be the same amount of milk and coffee in each cup.
4. Describe exactly how the cups should be prepared. Does every cup need to be exactly the same in every way except the order of the addition of milk and coffee? Can you actually make every cup identical?

How do you recommend that the characters decide if the model is able to tell whether the milk was added to the cup before or after the coffee? (In other words, how many cups does she have to correctly evaluate for you to conclude that she really can tell the difference?) Explain your choice.
I recommend that the model should get nine out of ten cups correct, stating whether milk was added before the coffee or added after the coffee. I think that nine out of ten is the best choice because we need to have at least 90% accuracy.
7. Without looking it up in a textbook or online, provide your own definition of "experimental design".
Experimental Design is when you take time and effort to organize the experiment properly to ensure that the right type of data, and enough of it, is available to answer the questions of interest as clearly and efficiently as possible.
Part II
1. Referring to your answers to the questions in Part I, was the hypothesis you chose different than the null hypothesis given by Fisher in his essay? Explain your
Fisher doesn't believe that all of the cups should be the same because he states that it is "impossible" to make every cup the same. Fisher says that each cup changes and has its differences from the next one. He says, "It is possible that the cup will differ perceptibly in the thickness or smoothness of the material." Fisher also says that during the experiment we don't really need to pay attention to the cups every detail. He says to pay attention too the important things like the amout of coffee and milk
The coffee served in Second Cup is also high quality and the drinks available strongly rival those in Starbucks. In the past decade there has been an explosive growth of 157% in the area of coffee shop market. Canadian coffee market share, new companies have limited to no space for growth in North America. Second Cup’s market share at the Canadian market is about 8%.Upon these facts and analysis there is an unlimited growth possibilities in the coffee market in Canada. There are different factors that do influence in the purchase of coffee from these outlets and the the way these coffees are priced. Customers are reluctant to get coffee from these outlets as the prices are too high than the coffees that could be made at home. There is a huge conflict between the pricing of coffees at these places and homemade ones. Coffee shops are determined to serve the best quality coffees which are been imported from South America and Africa, due to the rise in oil prices transportation charges have also been increased. And also due to different global climatic conditions the prices of these gourmet coffee beans have been increased.
My second big decision involved picking which size coffee maker I wanted. I had the choice to either pick a dual capacity or a high capacity coffee maker. The difference in the price between them are $3,000 and $6,000, respectively. The dual capacity
According to the Canadian coffee drinking study in 2013, coffee is the number one beverage of choice for adult Canadian. Because of the highly demand of coffee among the adult population, there is a lot of methods to make coffee. The method that used to make coffee unfortunately not efficient and consumed a lot of time and energy. Within the growing technological generation, new methods is being invented to make coffee in short time, less energy and that keep the coffee warmer for long hour. One of the coffee machine that invented is the KitchenAid KCM1202OB 12-Cup Glass Carafe Coffee Maker. This coffee maker machine consists a programmable display, removable water tank, water tank lid, permeant filter, Glass carafe and Brew basket. All
There are two common restaurants at DAH university Appello’s and Coffee Bean. Each one has a different kind of food. Appello’s has a variety sandwiches. On the other hand, Coffee bean has a limited kind of sandwiches. The coffee at Coffee bean is the best ever. However, Appello’s coffee tastes awful because It’s machine coffee. There are fresh juices at Appello’s, but Coffee Bean has only coffee and ice blended there is no fresh juices. The food at Coffee bean is fresher then Appello’s because they did it on request.
In Figure 12, we can see that A1 (tea with cane sugar) is the most preferred beverage with a percentage of 30% among the 10 beverages. The reasons given by the participants were: the tea had a strong and nice aroma and the sweetness is just nice. The second most preferred beverage was C1 (coffee with cane sugar & soymilk) with a percentage of 23%. The reasons were: coffee aroma match with the soymilk, adequate sweetness, strong coffee aftertaste, perfect balance between sweetness and bitterness. The third most preferred beverage was E1 (hot chocolate with cane sugar & soymilk) with a percentage of 17%. The reasons given were: The chocolate taste and aroma are very nice and is just right in the composition. The sweetness for each beverage were
Second Cup’s coffee or any other product. Most of the people that visit Second Cup zero times a month are high school students. These students don’t travel long distances on a regular basis. Hence they would’t come across many Second Cups because of their geographical situation. Most of the individuals that visit Second Cup more than 2 times a month are usually college and university students and working professionals. Well, that confirms our hypothesis. College, university students and working professionals all have to travel a fair distance every day to reach work or school. Therefore, they would come across atleast one Second Cup. Thus visiting
In order to run this experiment my partner and I had to order online the different scents. The scents we chose were banana, vanilla, cinnamon, smoke, and coffee. We also bought six little cups for each scent and one extra cup with only water, which is the control. The control cup is labeled 0. This would mean there was 31 total cups to buy. After all the supplies were ready, we first label all the cups 1 through 6. We then put 20
“I read this model and it compared it [technology integration] to coffee so you have the standard model which is just plain black coffee and there is one where you add cream and they compare it to like a latte and
The system allows consumers to buy a variety of coffee and make a cup of coffee that has the quality like the one you would buy in a gourmet coffee house for upwards of $3 to $5. Based on the surveys and focus groups that had been conducted people were looking for convenience, minimal clean-up, and great taste. Keurig made its decision to promote the system based on those factors and with units succeeding in local businesses now was the time to strike, while the “iron is hot”, a large percentage of survey takers said they would gladly buy the units that were proposed based on the information they were given.
What would be the strongest design for the research question? How does this compare to the design actually used?
The second major flaw in the coffee taste studies is the existence of external variables. It is evident that the first and third studies had underlying variables that may have significantly affected their outcomes. The first study notes that “the author of this study personally purchased coffee to go at four places, took them to his office, tasted them, made notes and drew conclusions” (pg. 63). This indicates a major flaw of this particular study because the time frames for which each cup of coffee was obtained and then consumed are inconsistent.
The product our group decided to chose was the Maxwell House Brewed Coffee Ready-to-Drink. We choose this product because the Maxwell House company lacked commitment they originally promised their customers convenience, which was not obtainable due to several reasons. The main reason this product did not work was because the 48 oz. carton was lined with aluminum foil which is not microwavable. We feel that this product could work if the container was changed to be microwavable and change the size to a single serving. By choosing this product we would like to determine whether our hypothesis was either correct or incorrect.
It is Saturday afternoon. You brew yourself a cup of coffee and are just about to pour cold milk into the coffee. The doorbell rings and you realize immediately that your friend needs your help for a few minutes this afternoon. If you want to have your coffee as warm as possible after you helped your friend, what would be wise to do? Should you pour the milk now, or after you come back? Or does it make no difference?
12. Please indicate which one of the following types of coffee you use most and which one you prefer most. (Mark one option only in each of the columns.) Used most Preferred Instant (e.g..
