Scientific Method Study

BSC1010 23FL/Maul ssignment No. 1 – The Scientific Method. Exercise. ▪ Read Chapter 1 Section 1.3 on the scientific method Use the scientific method to come up with a study where you measure something quantitatively (i.e. something you can measure with numbers). By answering the following questions you will be using the scientific method with its elements of observation, hypothesis, setting up the experiment/data collection, data analysis (includes graph), and conclusion. Dr. Maul’s EXAMPLE 1. What is your topic Dogs barking 2. What observations have you done In a dog park by my house I observe that Dobbermans and German shepherds seem to bark more than Golden retrievers 3. What is your hypothesis Golden retrievers bark less that other dogs 4. How will you set up your experiment In an experiment you must include the following factors: – control group and experimental group (Groups are also called treatments) – Independent variable and dependent variable – No. of replicates for each treatment: Control group (this is the reference group): Group 1 Golden retrievers (control) Experimental groups (all the groups that are not the control group: Group 2: Dobbermans; Group 3: German Shepherds Independent variable (this is the variable I CHOOSE to test): breed of dog Dependent variable: Number of times the dogs bark in a period of 1 hour (this is the variable that is dependent on the independent variable) No. of replicates for each treatment: 10 1 BSC1010 23FL/Maul Data collection: Make up a table of results (make up the data pretending that you took measurements. The table in this case will show How many times do dogs bark at strangers in a period of 1 h? Group or Golden Dobberman German Treatments retrievers Shepherds 1 0 4 4 2 2 4 5 3 1 3 3 4 3 5 4 5 0 2 3 6 2 5 4 7 1 4 2 8 1 3 0 9 1 4 2 10 2 3 4 Average 1.3 3.7 3.1 Analyze the data to be able to reach a conclusion: I calculated the average for each group, and the comparison of average data tells me that golden retrievers have a lower number of barks per hour Graph: Conclusion: Do you accept or reject the hypothesis? Conclusion (remember the conclusion always refers to the hypothesis): I accept my hypothesis. I found enough evidence to state that Golden retrievers bark less than other dogs. 2 BSC1010 23FL/Maul Now it is your turn: 1. What is your topic Luxury vs normal car brands 2. What observations have you done In the Brickell area I observed more luxury cars compared to the Kendall area where I saw more common cars. 3. What is your hypothesis? In Kendall there are more common cars because more middle class people live there in comparison to Brickell. 5. How will you set up your experiment? In an experiment you must include the following factors: – control group and experimental group (Groups are also called treatments) – Independent variable and dependent variable – No. of replicates for each treatment: Control group: Experimental groups: Independent variable (this is the variable I CHOOSE to test): Dependent variable (this is the variable that is dependent on the independent variable): No. of replicates for each treatment: 3 BSC1010 23FL/Maul Data collection: Make up a table of results (make up the data pretending that you took measurements. The table in this case will show How many times do dogs bark at strangers in a period of 1 h? Data collection: Make up a table with your data (make up the data pretending that you took measurements. Treatment Average Analyze the data to be able to reach a conclusion Graph your data: Conclusion: Do you accept or reject the hypothesis?
