Measurement issues. Data, even numerically coded variables, can be one of 4 levels - nominal, ordinal, interval, or ratio. It is important to identify which level a variable is, as this impact the kind of analysis we can do with the data. For example, descriptive statistics such as means can only be done on interval or ratio level data. Please list under each label, the variables in our data set that belong in each group.
Our experiment consists of adding one tablespoon of baking powder to each two cupcakes. There will be ten cupcakes in all and two will be controls, without baking powder. We will figure out which cupcake is the most “perfect” meaning the most fluffy, its circumference and height will be measured. Baking powder contains sodium bicarbonate, dry acid, and cream of tartar. These ingredients chemically changed out mixture into cupcakes.
The dependent variables in our experiment are the colors of the candies and the solvent that’s being used. In our experiment, we should be able to find out that the candy coating is actually a mixture of several pigments. Some pigments are more easily dissolved in the water and are pulled farther up the paper with the water. Certain pigments are more attracted to the paper so they will move slower up the paper. In other experiments done in the past the conclusion was only two M&M candies had two dyes involved in the candy coating.

The U.S. Department of Agriculture’s Continuing Survey of Food Intakes by Individuals discovered that 85% of Americans eat breakfast. With this large consumer base it comes to no surprise that bagel consumption has increased by 150% during the past decade, leading the trend toward simpler and more convenient breakfast foods according to U.S. Foodservice magazine. The bagel market itself is a $1.4 billion market that is continuously growing on a yearly basis (Boy, 2014). This provides that the product Hot Cheetos bagel has a high potential to hit the market since the bagel market itself is expanding and if a company does not act now they will not gain in market share. Bagels are a gaining popularity with 2/3 of its yearly revenue deriving from bagel shops that offer soups, sandwiches, and coffee.
This began the flours wars of the 1920’s when Betty Crocker was introduced as a figurative person that touched the lives of many with the “practical, thoughtful, and timely messages” (Marks 16) of cooking. The many recipe books published by General Mills captured the essence of simple, clean, easy baking that has remained timeless. The first picture cookbook “Betty Crocker Cookbook”, published in the 1950’s, became a national top best-seller. Since then, more than 250 Betty Crocker cookbooks have been published that have remained heavily used to this day. The hundreds of recipes and products promoted through these books have shown that General Mills could deliver the perfect products to the home and at the same time teach simple, nutritious ways to enjoy
The author of “Fast Food Nation”, Eric Schlosser, informed Food Inc. by mentioning, “In the 1970s, the top five beef-packers controlled only about 25% of the market. Today, the top four control more than 80% of the market.” (Kenner, Food Inc.) Schlosser statistics provides a reliable data which strengthen logos in a certain
The methods used in this lab experiment consisted of having four different drinking categories. These categories were non-drinkers, Coke, Gatorade, and water; the subjects will be chosen randomly to drink one of the drinks and then void 30 minutes after. After voiding, the subjects will have measured their urine temperature, urine volume, calculate specific density, urine pH and urine flow rate. After the calculations are done, the subjects will use the Labstix strips to measure if their urine tests positive or negative for blood, ketones, glucose, and protein. In my hypothesis I will expect water to have the greatest urine volume and flow rate, then all other drinks (Gatorade, Coke, and non-drinkers).
There are plenty of restaurants around Calgary, however none are quite like The Silver Spoon. Buttermilk Fine Waffles is the most similar, with a focus on a very specific food item, traditionally served at breakfast. Buttermilk serves waffles all day, running into the late hours of the night as well. However, Buttermilk does very little outside of that very specific menu item, and is located downtown, therefore it is not a perfect comparison to The Silver Spoon.
The standard curve produced in the Beer-Lambert Law graph can be used to determine the protein concentrations of 2% milk, a protein drink, and soy milk, by knowing their absorbance. This method consists of measuring the absorbance values of 6 standard proteins in this case, and use this information to find the protein concentration of the unknowns. From this, the absorbance of 2% milk, a protein drink, and soy milk are compared with the graph to find their true protein concentrations. Their protein concentrations are important because the Canadian Food Inspection Agency also have other standards regarding the claims a food production company can make towards their products. In other words, food companies have to respect the Summary Table of Protein Claims in regards to special claims made on their tenure of proteins.
Year 6 children investigated how the length of the straws affects the sound it makes. The pattern that was noticed in the results shows that the shorter the straw gets, the higher the pitch of sound is produces. From the results I have noticed that the length of the straws is the independent variable and the sound is dependent variable. This meant that the straws length had to be changed in order to receive results of the sounds. I gathered from the information that students were using different length straws to determine the pitch.
In conclusion, from the collected data, the lack of the change in characteristics from Biuret’s solution suggests that there is a minimal amount of protein in both of the McDonald’s happy meals, if
With this in mind, some responses led to key findings that were extracted from the research: Findings Interpretation Inferences Emotional attachment of family with the cookies Baking spreads happiness among the family Baking experience needs to be linked with Pillsbury brand Branded and Lapsed users have alternative issues with product Lapsed users had quality concerns and poor perception about attributes of product Current branding and advertising wasn’t communicating the core competencies of the brand Moms looking for practical solution to please kids Pleasing kids and practicality integral for mothers Right product with right values need to be communicated in their advertisements HYPOTHESIS Attributes Relation to consumer Implication Quality and Nourishment The more the better Currently company wasn’t communicating these 2 attributes Multiple uses of cookies The higher the better If company can find ways to increase methods of baking cookies it can increase sales considerably Convenience of usage The greater the better It is the existing core competency and the company should continually remind customer about

Data analysis at work time the teacher may hear the children discussing the ice cream truck that came by their house. During large group time the teacher will draw a chart with different flavors of ice creams and gather the children data based on their favorite ice cream. Children can explore shapes outside when exploring the playground. The teacher can ask the children about the different type of shapes they see on the playground or turn the shape activity into games such as “I spy” or shape hunt. (Gainsley,
