1. What are the Z and t-tests, and when should you use each?

Explain the purpose and differences between Z-tests and t-tests. Describe scenarios where one test is preferred over the other.

2. How would you reformat student test score data for better analysis?

Given two datasets of student test scores, identify drawbacks in their current organization. Suggest formatting changes to improve usability and discuss common issues in messy datasets.

3. What metrics would you use to evaluate the value of marketing channels?

Given data on marketing channels and costs for a B2B analytics dashboard company, identify key metrics to determine the value of each marketing channel.

4. How would you determine the next partner card using customer spending data?

With access to customer spending data, outline a method to identify the best partner for a new credit card offering.

5. How would you investigate if a redesigned email campaign led to increased conversion rates?

Analyze a scenario where a new email campaign coincides with an increase in conversion rates. Determine how to investigate whether the campaign caused the increase or if other factors were involved.

6. How would you use linear interpolation to fill missing temperature data in a time-series dataframe?

A climate research organization has a time-series dataframe with daily temperature readings for different cities. Some temperature readings are missing. Write a Python function using Pandas to perform linear interpolation to estimate and fill the missing data. Ensure the interpolation considers data from the same city only. Assume no consecutive missing data and valid temperature data at the start and end of the dataframe.

7. How does random forest generate the forest? Additionally, why would we use it over other algorithms such as logistic regression?

Explain the process of how random forest generates multiple decision trees to form a forest. Discuss the advantages of using random forest over logistic regression, such as handling non-linear data and reducing overfitting.

8. Let’s say we’re comparing two machine learning algorithms. In which case would you use a bagging algorithm versus a boosting algorithm?

Compare two machine learning algorithms. Describe scenarios where bagging (e.g., Random Forest) is preferred for reducing variance and boosting (e.g., AdaBoost) is preferred for reducing bias. Provide examples of tradeoffs between the two.

9. Let’s say you work for a bank that gives out personal loans. Your co-worker develops a model that takes in customer inputs and returns if a loan should be given or not.

  1. What kind of model did the co-worker develop?

10. What’s the difference between Lasso and Ridge Regression?

Explain the key differences between Lasso and Ridge Regression, focusing on their regularization techniques (L1 for Lasso and L2 for Ridge) and their impact on feature selection and model complexity.

11. What are the key differences between classification models and regression models?
