Module 4: *Course challenge*

Looking for ‘ask questions to make data driven decisions course challenge answers‘?

In this post, I provide accurate answers and detailed explanations for Module 4: *Course challenge* of Course 2: Ask Questions to Make Data-Driven Decisions – Google Data Analytics Professional Certificate.

Whether you’re preparing for quizzes or brushing up on your knowledge, these insights will help you master the concepts effectively. Let’s dive into the correct answers and detailed explanations for each question.

1. Scenario 1, questions 1-5

You’ve just started a job as a data analyst at a small software company that provides data analytics and business intelligence solutions. Your supervisor asks you to kick off a project with a new client, Athena’s Story, a feminist bookstore. They have four existing locations, and the fifth shop has just opened in your community.

Athena’s Story wants to produce a campaign to generate excitement for an upcoming celebration and introduce the bookstore to the community. They share some data with your team to help make the event as successful as possible.

Your task is to review the assignment and the available data, then present your approach to your supervisor. Click the link below to access the email from your supervisor:

Then, review the email, and the Customer Survey and Historical Sales datasets.

If you don't have a Google account, you can download the CSV files directly from the attachments below.

After reading the email, you notice that the acronym WHM appears in multiple places. You look it up online, and the most common result is web host manager. That doesn’t seem right to you, as it doesn’t fit the context of a feminist bookstore. How do you proceed?

  • Send your supervisor a polite, concise email, asking them to confirm the meaning of WHM.
  • Schedule a meeting with your supervisor, the client, and another analyst on your team to figure out the meaning.
  • Call the client to ask what WHM means and inform them that using acronyms is not a professional business practice.
  • Proceed with the project assuming WHM must mean web host manager.

2. Scenario 1 continued

Now that you know WHM stands for Women’s History Month, you review the Customer Survey dataset which contains both qualitative and quantitative data.

To use the template for the dataset, click the link below and select “Use Template.”

OR

If you don't have a Google account, you can download the CSV file directly from the attachment below.

The data in column F (Survey Q6: What types of books would you like to see more of at Athena's Story?) is quantitative.

  • True
  • False

Explanation:
Qualitative data consists of non-numerical responses, such as text describing customer preferences, as in Survey Q6.

3. Scenario 1 continued

Next, you review the customer feedback in column F of the Customer Survey dataset.

To use the template for the dataset, click the link below and select “Use Template.”

Link to template: Customer Survey

OR

If you don't have a Google account, you can download the CSV file directly from the attachment below.

The attribute of column F is, “Survey Q6: What types of books would you like to see more of at Athena's Story?” In order to verify that children’s literature and feminist zines are among the most popular genres, you create a visualization. This will help you clearly identify which genres are most likely to sell well during the Women’s History Month campaign.

The chart you create demonstrates the percentages of each book genre that make up the whole. It’s called an area chart.

  • True
  • False

4. Now that you’ve confirmed that children’s literature and feminist zines are among the most requested book genres, you review the Historical Sales dataset.

To use the template for the dataset, click the link below and select “Use Template.”

Link to template: Historical Sales

If you don't have a Google account, you can download the CSV file directly from the attachment below.

You’re pleased to see that the dataset contains data that’s specific to children’s literature and feminist zines. This will provide you with the information you need to make data-inspired decisions. In addition, the children’s literature and feminist zines metrics will help you organize and analyze the data about each genre in order to determine if they’re likely to be profitable.

Next, you calculate the total sales over 52 weeks for feminist zines. You type =CALCULATE(E2-E53) but get an error. What is the correct syntax?

  • =SUM(E2:E53)
  • =MAX(E2:E53)
  • =COUNT(E2:E53)
  • =CALC(E2:E53)

5. Scenario 1 continued

After familiarizing yourself with the project and available data, you present your approach to your supervisor. You provide a scope of work, which includes important details, a schedule, and information on how you plan to prepare and validate the data. You also share some of your initial results and the pie chart you created.

In addition, you identify the problem type, or domain, for the data analysis project. You decide that the historical sales data can be used to provide insights into the types of books that will sell best during Women’s History Month this coming year. This will also enable you to determine if Athena’s Story should begin selling more children’s literature and feminist zines.

Using historical data to make informed decisions about how things may be in the future is an example of which problem domain?

  • Making predictions
  • Identifying themes
  • Spotting something unusual
  • Discovering connections

Explanation:
Using historical data to forecast future trends involves predictive analytics, a key component of problem-solving in data analysis.

15. Scenario 2 continued

Now, the vice president presents a situation having to do with resolving challenges and meeting stakeholder expectations. Consider and respond to the following question.

You’re working on a rush project, and you discover your dataset is not clean. Even though it has numerous nulls, redundant data, and other issues, the primary stakeholder insists that you move ahead and use it anyway. The project timeline is so tight that there simply isn’t enough time for cleaning. How would you handle that situation?

  • Communicate the situation to your supervisor and ask for advice on how to handle the situation with the stakeholder.
  • The stakeholder is in charge. It’s best to do as they say and use the unclean dataset.
  • Clean the data as quickly as you can. It’s not perfect, but it’s better than it was before, and this way you can meet the deadline.
  • Contact the stakeholder’s boss to let them know about the issue and ask for help managing the stakeholder’s expectations.
