Question.3472 - Instructions Using the scientific method, you are going to investigate a hypothesis about food quality. You must document each step of the scientific method. First choose a not-homemade food product that you think that you can distinguish a quality of in a blind taste test. You are going to make a comparison between two or more food items and determine if you can distinguish them apart from one another. This could be a comparison between two different brand products like Coke® and Pepsi® or between a store brand and a name brand (Ex: Oreos® and the generic store sandwich cookie). You could also test if you can tell a flavor difference between items of the same product like is there a flavor difference between the different colors of Skittles® or Froot Loops®. You decide what you want to test, but you will need to consume it as part of your assignment. If you have any problems finding something to test for this assignment, please contact the instructor. This assignment is NOT meant to be a test to see which item is better. That is an opinion question. Please develop a testable theory and hypothesis. Step 1. Develop a theory about the quality of the food you are testing. State this like a scientist, in a matter-of-fact way (e.g. “There is detectable difference between...”). Step 2. What is the hypothesis? Make sure that this is written specifically to reflect how you’re testing the theory (e.g. “I predict that ... when I ...[state the basic design of your experiment].” Step 3. How will you test this hypothesis? Step 4. Test, record, & summarize your data. Step 5. What conclusions can you draw from your data? Step 6. Taking your conclusions into account, if you were to continue doing research on the taste of this food, what would your next hypothesis be?

Student Name: Calvin kai Course Code: PSY07303 Date: Sept, 9th ,2024 Research Methods Online Assignment 1 - Test a Hypothesis Step 1: Develop a Theory There is a vivid difference in taste that is quite detectable between Oreo? cookies and store-brand chocolate sandwich cookies. Step 2: Hypothesis I predict that when I conduct a blind taste test comparing Oreo? cookies and a generic store-brand chocolate sandwich cookie, I will be able to understand a difference and distinguish between the two based on flavor and texture. Participants will also be able to correctly identify the Oreo? cookie at a rate significantly higher than chance. Step 3: Testing the Hypothesis I will conduct a blind taste test for testing the hypothesis with the following methodology: Participants Minimum 20 participants will be hired for the study Participants will be adults. They will age between 18-65 with no known taste or smell impairments Materials One package of Oreo? cookies One package of a generic store-brand chocolate sandwich cookies Opaque cups which are labelled as "A" and "B" to serve the cookies Procedure In a random order, each participant will be getting one cookie from each brand, that will be labelled as "A" and "B". Participants will taste each cookie and answer the following questions: (A or B), Which cookie do you think is the Oreo? cookie? Each cookie flavour should be rated on a scale of 1-5 (1 = very poor, 5 = excellent). Each cookie texture should be rated on a scale of 1-5 (1 = very poor, 5 = excellent). For each cookie rate your overall preference on a scale of 1-5 (1 = dislike extremely, 5 = like extremely). I will outline the testing, recording, and summarizing of data based on a simulated taste test scenario for conducting a blind taste test to compare Oreo? cookies and a generic store-brand chocolate sandwich cookie. Step 4: Test, Record, & Summarize Data Test Procedure 1. Participants: A total of 20 participants were recruited for the taste test, a mix of friends and family who have age between18-65, with no prior known taste impairments. 2. Sample Preparation: From a local grocery store, Oreo? cookies were purchased Apart from thar a generic store-brand chocolate sandwich cookie was purchased too. In opaque cups labeled "A" and "B , each cookie was placed to ensure blind testing. 3. Taste Test Execution: Participants were instructed to taste both cookies and answer the following questions: According to you, which cookie do you think is the Oreo? cookie (A or B)? Rate each cookies flavour on a scale of 1-5. Rate each cookies texture on a scale of 1-5. Rate your overall preference for each cookie on a scale of 1-5. Data Collection Participant Guess (A/B) Flavor Rating (1-5) Texture Rating (1-5) Overall Preference (1-5) 1 A 4 5 4 2 B 3 4 3 3 A 5 5 5 4 A 4 4 4 5 B 2 3 2 6 A 5 5 5 7 A 4 4 4 8 B 3 3 3 9 A 5 5 5 10 B 2 3 2 11 A 4 4 4 12 A 5 5 5 13 B 3 3 3 14 A 4 4 4 15 A 5 5 5 16 B 2 3 2 17 A 4 4 4 18 A 5 5 5 19 B 3 3 3 20 A 4 4 4 Data Summary Identification Accuracy Number of correct identifications of Oreo?: 12 out of 20 Identification accuracy: 60% Average Ratings Flavor Ratings: Oreo? (A): Average = 4.4 Generic (B): Average = 3.0 Texture Ratings: Oreo? (A): Average = 4.4 Generic (B): Average = 3.2 Overall Preference Ratings: Oreo? (A): Average = 4.3 Generic (B): Average = 2.8 Conclusion from Data At a rate of 60%, the participants were comfortable to recognize the Oreo? cookie correctly as indicated by the data; that is above the chance level of 50%. On top of that, a significant higher rating in flavor, texture, and overall preference were received by the Oreo? cookies as compared to the generic cookies. From this it is understandable that the hypothesis has a detectable difference in taste and quality between the two brands. Next Hypothesis Based on the findings, the next hypothesis possibly could be: "The flavor and texture differences between Oreo? cookies and generic chocolate sandwich cookies are primarily due to the specific ingredients used in the Oreo? formulation, such as higher quality cocoa and cream." Future research can actually involve analyzing the ingredient lists and conducting further taste tests with many other variations in ingredients for exploring their impact on taste perception.More Articles From Research
