Question

review the following video. identifying parts of scientific method in an experiment. when i went to the doctor before school started, the nurse took my blood pressure with the inflatable cuff. my blood pressure was too high and my doctor told me i needed to make some changes to my diet. he suggested that i choose a whole grain cereal for breakfast. there are many whole grain cereals at the store. i chose to try cheerios cereal. i want to know if it will help my blood pressure go down. question/problem: does affect? minimize video. using the scientific method, develop a question related to the covid - 19 pandemic. state your question. what would be your independent variable? what would be your dependent variable? what would be your hypothesis? what kind of data can you collect to answer your question? how would you report your results?

Explanation:

Step1: Develop a question

Does the type of face - mask (cloth, surgical, N95) affect the transmission rate of Covid - 19?

Step2: Identify independent variable

The independent variable is the type of face - mask (cloth, surgical, N95).

Step3: Identify dependent variable

The dependent variable is the transmission rate of Covid - 19.

Step4: Formulate hypothesis

Hypothesis: N95 masks will have the lowest transmission rate of Covid - 19 compared to surgical and cloth masks, as they provide a better seal and filtration.

Step5: Determine data collection

Collect data on the number of Covid - 19 cases among individuals using different types of masks in similar settings (e.g., healthcare facilities, public spaces). Also, record information about exposure levels, duration of mask - wearing, etc.

Step6: Decide result reporting

Report the results in a scientific paper, presenting the data in tables and graphs showing the relationship between mask type and transmission rate. Include statistical analysis to determine if there are significant differences between the groups.

Answer:

Question: Does the type of face - mask (cloth, surgical, N95) affect the transmission rate of Covid - 19?
Independent variable: Type of face - mask (cloth, surgical, N95)
Dependent variable: Transmission rate of Covid - 19
Hypothesis: N95 masks will have the lowest transmission rate of Covid - 19 compared to surgical and cloth masks, as they provide a better seal and filtration.
Data collection: Number of Covid - 19 cases among individuals using different types of masks in similar settings, along with exposure levels and duration of mask - wearing.
Result reporting: In a scientific paper with tables, graphs, and statistical analysis.
