[All Databricks-Certified-Professional-Data-Scientist Questions]

In which lifecycle stage are appropriate analytical techniques determined?

AModel planning

BModel building

CData preparation

DDiscovery
In Phase 3, the data science team identifies candidate models to apply to the data for clustering, classifying, or finding relationships in the data depending on the goal of the project, It is during this phase that the team refers to the hypotheses developed in Phase 1, when they first became acquainted with the data and understanding the business problems or domain area. These hypotheses help the team frame the analytics to execute in Phase 4 and select the right methods to achieve its objectives.
Some of the activities to consider in this phase include the following: Assess the structure of the datasets. The structure of the datasets is one factor that dictates the tools and analytical techniques for the next phase. Depending on whether the team plans to analyze textual data or transactional data, for example, different tools and approaches are required.
Ensure that the analytical techniques enable the team to meet the business objectives and accept or reject the working hypotheses. Determine if the situation warrants a single model or a series of techniques as part of a larger analytic workflow. A few example models include association rules and logistic regression Other tools, such as Alpine Miner, enable users to set up a series of steps and analyses and can serve as a front-end user interface (Ul) for manipulating Big Data sources in PostgreSQL.

Wait, there's an 'Alpine Miner' involved? I'm sold! That's gotta be the answer. Who doesn't love a good miner?

Ah, the age-old debate of which came first, the chicken or the egg? I mean, do we determine the analytics based on the data, or the data based on the analytics? This is deep, my friends.

This question is making my head spin. I'm just going to go with my gut and say 'D) Discovery'. Sounds like the most logical choice to me.

I'm a little confused - isn't Model building the stage where you actually choose and apply the analytical techniques? That's where the magic happens!

Nah, I'm going with Discovery. That's where you really dive into the data and figure out what's going on. The analytical techniques flow from that understanding.

I think this is a trick question. The answer is definitely Data preparation - you need to clean and transform your data before you can even start modeling, right?

Hmm, seems like the appropriate analytical techniques are determined during the Model planning stage. That makes sense, as you need to plan your approach before actually building the model.

Wait, is this a trick question? I mean, shouldn't we be determining the analytical techniques throughout the entire lifecycle, not just in one specific phase?

The data preparation phase is key in determining the appropriate analytical techniques. You can't just jump straight to the modeling without first understanding the data structure and addressing any quality or consistency issues.
