Don’t underestimate the importance of a good data science project in your portfolio—it can be a defining factor in your career progression. While learning is the first step on the ladder to career success, you must also demonstrate your abilities and intuitive mindset by working on real-life projects.

The great aim of education is not knowledge but action.

What Is the 365 Learning Data Challenge?

For this challenge, you’ll take on the role of a data scientist at 365. Your task is to analyze data on student engagement, gather insights, and identify key opportunities for improvement.

A work desk with a large computer screen, wireless mouse and keyboard, a phone, mug, desk lamp, notebook, and pencil holder full of wooden pencils. On the screen is a dashboard with various types of charts and metrics.

This project can be completed in one of two parts (or both, depending on your preferences):

  • Design a dashboard
  • Build a machine learning model

Both options are valid for participation. You can submit either a dashboard or an ML model as an eligible entry or complete both to increase your chances of winning.

We’ll outline each part in its corresponding sections of this article.

Additionally, you can take this challenge in two ways—unguided or guided. The former provides only the bare bones of the task, while the latter gives you a specific direction to follow, providing ideas on the analyses and types of visualizations that can be included. The guided approach is available only inside the 365 platform—access it by registering with a Free Plan account. No credit card is required.

Feel free to use any technology you are most comfortable with or challenge yourself by learning a new skill.

How to Participate?

Once you’re ready with your project(s), share your work with us as a LinkedIn post(s).

  • Add a screenshot of your work to your LinkedIn post (required for dashboard, optional for ML).
  • Share your motivation for taking on the challenge.
  • Describe your method and findings (preferably as bullet points).
  • Include relevant metrics that evaluate the model’s performance (ML only).
  • Tag us @365 Data Science and use the hashtag #365learningdatachallenge.
  • Include a public link to your interactive dashboard (optional).
  • Attach a link to a GitHub repository where you’ve stored relevant code (required for ML, optional for dashboard).

To be eligible for the challenge, you need to share your project(s) via your LinkedIn profile no later than December 2, 2022, at 11:59 PM EST.

What Can You Win?

The best part about a challenge—aside from the winners’ bragging rights, of course—is the prizes. And we’ve got some truly incredible ones in store for you. By entering the 365 Learning Data Challenge, you’re in the running to win one of the following:

  • 1st place: Apple iPad Pro 512GB Wi-Fi
  • 2nd place: Apple Air Pods 3rd generation
  • 3rd and 4th place: Stylish 365 gear

The first-place prize is an Apple iPad Pro, the second-place prize is a pair of Apple 3rd Generation Airpods, and the third- and fourth-place winners will get a branded backpack, t-shirt, and pen with the 365 Data Science logo.

Both guided and unguided projects enter the competition on equal footing and are eligible to win. Whether you proceed with one or the other depends entirely on your preferences.

The winning entries will be determined based on the number of reactions their posts receive on LinkedIn. Multiple submissions are allowed to account for the two parts of the project, in which case your score would be based on the summed number of reactions across your challenge-related posts.

Project Description

365 Data Science is an online learning platform specializing in data science courses. Students learn by watching video content, then evaluate their knowledge by taking quizzes, practice exams, course exams, and career track exams. The exams can be attempted more than once.

As a data scientist at 365, your task is to analyze an extract of a database on student engagement and identify key areas of improvement. The period under analysis is January 1, 2022 – October 20, 2022.

Keeping in mind the metrics that 365’s CEO might find useful, build a single-page dashboard or machine learning model and discuss your findings.

Resources

As part of the challenge, you will have access to the project database and a series of helpful resources to use as you work.

  • You can download and work with the data in one of two ways: a MySQL database of 11 tables or a collection of 11 .csv files.
  • You are not obligated to use all tables included in the database—only those you find relevant for your analysis.

Download the resources files here.

And in case you need a knowledge boost, here are some of the courses the 365 team recommends to help you with this challenge:

Project Structure

The 365 Learning Data Challenge is made up of two parts—dashboard design and building a machine learning model.

Both include additional tasks you need to complete to produce effective results.

You can approach this project in one of two ways:

  • Unguided: You only need to read the brief description of each task and analyze the metrics you find most relevant for depicting students’ engagement.
  • Guided: You can use optional descriptions with detailed instructions regarding each task. Please note that this option offers ideas, not solutions. There is no right or wrong way to complete the challenge.

In this article, you will find only task descriptions for the unguided project approach. If you’d like to complete the challenge using the guided instructions, sign up to the 365 platform with a Free Plan to be granted access.

1.      Dashboard Design

Dashboard Structure

The main objective is to build a single-page dashboard with key metrics, insights, and visualizations on student engagement.

Start with defining the questions you would like to give answers to. Determine what visualization best fits a given query and how the information could be filtered. Then, create a rough sketch of the dashboard.

Data Preparation

Your dashboard needs clean data to present precise results. You must carefully prepare the data to feed it into your favorite visualization program and create the plots.

You can use MySQL to retrieve and join information from multiple tables, creating a sophisticated analysis. You are also welcome to perform this pre-processing step in Python or any other programming language you feel most comfortable with. You can also manipulate the relevant data directly in Tableau, Power BI, or another visualization tool.

Dashboard Construction

This is where you reveal your most creative side!

Create each visualization separately, then build your single-page dashboard chart by chart. Make sure it is visually attractive, intuitive, and practical.

Results Discussion

After completing your dashboard, you should present your findings. Discuss the plots you’ve built, the information they convey, and the conclusions we can draw from them.

This part is essential as it is the underlying reason for creating a dashboard of this sort. Given specific results and certain information from the dashboard, the 365 team can determine what actions can be taken to improve the company’s growth and deliver its students the best learning experience.

2. Building a Machine Learning Model

The second task has you develop a machine learning model to predict whether a Free Plan user would convert to a paid subscriber or not.

Think of the features that could help determine the outcome. Share your result by supporting them with relevant metrics, a confusion matrix, or another industry-standard method for model evaluation.

Note that this classification problem deals with a heavily imbalanced dataset.

FAQ

Am I eligible for a prize if I submit my work after the deadline?
Unfortunately, we cannot make any exceptions for late entries. Projects submitted past the deadline (Dec 2, 2022, at 11:59 PM PST) will not be eligible for a prize.
Can I participate in both parts of the challenge?
Yes, you are very welcome to! If you opt for both the dashboard and the ML part, then create two separate LinkedIn posts. Your score will make up the summed reactions you receive on both posts and, as a result, increase your chances of winning.
Does a guided project have less chance of winning compared to an unguided one?
No, an unguided project does not carry more weight than a guided one. Both enter the competition equally and are eligible for the same prizes.
I have opted for the guided version of the project but also have other ideas for improvement. Could I implement them?
You are free to add any personal touches to the guided project. That version serves as inspiration, offering ideas rather than solutions. Create the solution you are most proud of!
