Google Associate Data Practitioner Exam - Topic 4 Question 3 Discussion

Actual exam question for Google's Associate Data Practitioner exam
Question #: 3
Topic #: 4
[All Associate Data Practitioner Questions]

Your company uses Looker as its primary business intelligence platform. You want to use LookML to visualize the profit margin for each of your company's products in your Looker Explores and dashboards. You need to implement a solution quickly and efficiently. What should you do?

Show Suggested Answer Hide Answer
Suggested Answer: B

Defining a new measure in LookML to calculate the profit margin using the existing revenue and cost fields is the most efficient and straightforward solution. This approach allows you to dynamically compute the profit margin directly within your Looker Explores and dashboards without needing to pre-calculate or create additional tables. The measure can be defined using LookML syntax, such as:

measure: profit_margin {

type: number

sql: (revenue - cost) / revenue ;;

value_format: '0.0%'

}

This method is quick to implement and integrates seamlessly into your existing Looker model, enabling accurate visualization of profit margins across your products.

Applying a filter sounds like it could help narrow down the results, but it doesn't actually calculate the profit margin, right? I think we need to focus on the measure instead.

I remember a practice question where we had to categorize products. But in this case, it feels like just calculating the margin directly would be more efficient.

I'm not entirely sure, but creating a derived table could be useful if we need to do more complex calculations later on.

I think defining a new measure for profit margin using revenue and cost makes the most sense. It seems like the quickest way to get the data we need.

I'm a little confused by the question. Do we need to show the actual profit margin values, or just categorize the products based on their margins? I'm leaning towards option C, but I want to make sure I fully understand the requirements first.

Okay, I've got this! Creating a derived table to pre-calculate the profit margin seems like the most efficient solution. That way, I don't have to worry about the calculation in my Looker model, and I can just focus on the visualization.

Hmm, I'm a bit unsure about this one. I'm not super familiar with Looker, so I'll need to think through the pros and cons of each approach carefully. Maybe I'll start by reviewing the Looker documentation on measures and dimensions.

This looks like a straightforward question about visualizing profit margin in Looker. I think I'll go with option B and define a new measure to calculate the profit margin directly.

Haha, I bet the product team is really hoping we all choose B. They're probably tired of explaining profit margins to the sales team!
