๐โ๏ธHere are Data Analytics-related questions along with their answers:
1.Question: What is the purpose of exploratory data analysis (EDA)?
Answer: EDA is used to analyze and summarize data sets, often through visual methods, to understand patterns, relationships, and potential outliers.
2. Question: What is the difference between supervised and unsupervised learning?
Answer: Supervised learning involves training a model on a labeled dataset, while unsupervised learning deals with unlabeled data to discover patterns without explicit guidance.
3.Question: Explain the concept of normalization in the context of data preprocessing.
Answer: Normalization scales numeric features to a standard range, preventing certain features from dominating due to their larger scales.
4. Question: What is the purpose of a correlation coefficient in statistics?
Answer: A correlation coefficient measures the strength and direction of a linear relationship between two variables, ranging from -1 to 1.
5. Question: What is the role of a decision tree in machine learning?
Answer: A decision tree is a predictive model that maps features to outcomes by recursively splitting data based on feature conditions.
6. Question: Define precision and recall in the context of classification models.
Answer: Precision is the ratio of correctly predicted positive observations to the total predicted positives, while recall is the ratio of correctly predicted positive observations to all actual positives.
7. Question: What is the purpose of cross-validation in machine learning?
Answer: Cross-validation assesses a model's performance by dividing the dataset into multiple subsets, training the model on some, and testing it on others, helping to evaluate its generalization ability.
8. Question: Explain the concept of a data warehouse.
Answer: A data warehouse is a centralized repository that stores, integrates, and manages large volumes of data from different sources, providing a unified view for analysis and reporting.
9. Question: What is the difference between structured and unstructured data?
Answer: Structured data is organized and easily searchable (e.g., databases), while unstructured data lacks a predefined structure (e.g., text documents, images).
10. Question: What is clustering in machine learning?
Answer: Clustering is a technique that groups similar data points together based on certain features, helping to identify patterns or relationships within the data.

Can you use Chat GPT as a data analyst?
The answer to this question is yes, but you need to be cautious about using Chat GPT on the job (and even while learning analytics) for the following reasons.
1. Chat GPT gets things wrong. A lot.
If you use Chat GPT to write code, you better know that coding language extremely well, because you gotta be able to fact check and alter the response you get from Chat GPT.
For this reason, I would recommend staying away from Chat GPT when youโre learning SQL, Python, etc so you thoroughly learn the code without becoming dependent on AI.
2. You absolutely CANNOT paste company data into Chat GPT
As data analysts we work with highly confidential data that we must exercise great caution to protect.
For this reason, no matter how secure Chat GPT says it is, you must never paste company data into the application.
3. Some companies and bosses may not allow the use of Chat GPT
This is a reality in the world of tech and data since the avalanche of AI tools and features over the last couple years.
Iโve heard of some companies that block Chat GPT altogether, and some managers who advise against using it out of fears for security and other reasons.
Given all three of these reasons, feel free to play around with Chat GPT and AI and learn about them, but donโt become overly dependent on these tools.
