Correct: Collaborating with a social scientist to provide insights into human bias and social contexts is an effective way to avoid bias in your data. *Course Challenge*1. Scenario 1, question 1-5Next, you continue to the prepare step. You access the database and write a query to retrieve data about Splashtastic. You notice that there are only 38 rows of data, representing the company’s 38 stores. In addition, your dataset contains five columns: Store Number, Average Daily Customers, Average Daily Splashtastic Sales (Units), Average Daily Splashtastic Sales (Dollars), and Average Total Daily Sales (All Products).Considering the size of your dataset, what’s the best way to proceed with the process and analyze steps?
Correct: Spreadsheets work well for processing and analyzing a small dataset, such as the one you’re using. 2. Scenario 1 continuedNow, it’s time to process the data. As you know, this step involves finding and eliminating errors and inaccuracies that can get in the way of your results. While cleaning the data, you notice there’s missing data in one of the rows. What might you do to fix this problem? Select all that apply.
Correct: You could ask your supervisor or a colleague for guidance. Asking questions helps you learn and avoid mistakes. 3. Scenario 1 continuedOnce you’ve found the missing information, you analyze your dataset.During analysis, you create a new column F. At the top of the column, you add the attribute Average Percentage of Total Sales – Splashtastic. Select the correct definition for an attribute.
Correct: An attribute is a characteristic or quality of data used to label a column. 4. Scenario 1 continuedNext, you determine the average total daily sales over the past 12 months at all stores. The range that contains these sales is E2:E39. Identify the correct way to write your function.
Correct: The function begins with an equal sign (=), and the range is E2 through E39. 5. Scenario 1 continuedYou’ve reached the share phase of the data analysis process. It involves which of the following? Select all that apply.
Correct: The share phase involves creating data visualizations, preparing your presentation, and communicating your findings to stakeholders. 6. Scenario 2, question 6-10You’ve been working for the nonprofit National Dental Society (NDS) as a junior data analyst for about two months. The mission of the NDS is to help its members advance the oral health of their patients. NDS members include dentists, hygienists, and dental office support staff.The table is dental_data_table, and the column name is zip_code. How do you complete the following query?
Correct: The correct syntax is WHERE zip_code = 81137. WHERE indicates where to look for information. The column name is zip_code. And the database is being asked to return only records matching zip code 81137. 7. Scenario 2 continuedThe dataset your supervisor retrieved and imported into a spreadsheet includes a list of patients, their demographic information, dental procedure types, and whether they attended their follow-up appointment. To use the dataset for this scenario, click the link below and select “Use Template.”The patient demographic information includes data such as age and gender. As you’re learning, it’s your responsibility as a data analyst to make sure your analysis is fair. The fact that the dataset includes people who all live in the same zip code might get in the way of fairness.
Correct: It’s your responsibility as a data analyst to make sure your analysis is fair. Although many zip codes do reflect diverse populations, a better choice would be to include data about people who live in multiple zip codes. 8. Scenario 2 continuedAs you’re reviewing the dataset, you notice that there are a disproportionate number of senior citizens. So, you investigate further and find out that this zip code represents a rural community in Colorado with about 800 residents. In addition, there’s a large assisted-living facility in the area. Nearly 300 of the residents in the 81137 zip code live in the facility.Now, the NDS campaign will be about educating dental offices on the challenges faced by senior citizens and finding ways to help them access quality dental care.Fill in the blank: Changing the business task involves defining a new _____.
Correct: A business task is the question or problem data analysis answers for a business. 9. Scenario 2 continuedYou continue with your analysis. In the end, your findings support what you discovered during your online research: As people get older, they’re less likely to attend follow-up dental visits.But you’re not done yet. You know that data should be combined with human insights in order to lead to true data-driven decision-making. So, your next step is to share this information with people who are familiar with the problem. They’ll help verify the results of your data analysis.The people who are familiar with a problem and help verify the results of data analysis include customers and competitors.
Correct: Subject-matter experts look at the results of data analysis to identify any inconsistencies, make sense of the gray areas, and eventually validate the choices being made. 10. Scenario 2 continuedThe subject-matter experts are impressed by your analysis. The team agrees to move to the next step: data visualization. You know it’s important that stakeholders at NDS can quickly and easily understand that older people are less likely to attend important follow-up dental appointments. This will help them create an effective campaign for members.It’s time to create your presentation to stakeholders. It will include a data visualization that demonstrates the trend of people being less likely to attend follow-up appointments as they get older. Which type of chart will be most effective?
Correct: A line chart is effective for tracking trends over time, such as people attending fewer follow-up appointments as they get older.
