WCC1: Dr. B’s Research Lab - The Mystery Dataset 🔬
🔬 Dr. B’s Research Lab: The Mystery Dataset
Weekly Coding Checkup 1 - Enhanced Version
🧪 The Story Begins…
Welcome to Dr. B’s Research Laboratory!
You’ve just been hired as a Junior Data Analyst at the prestigious Analytics Academy. Dr. B has discovered a mysterious dataset that could revolutionize the diamond industry, but the data is locked away and needs your coding skills to unlock its secrets!
Your mission for the next 10 weeks: Help Dr. B solve the Great Diamond Mystery by mastering the tools of data science. Each week, you’ll gain new powers (R skills) that bring you closer to the ultimate revelation.
🎯 This Week’s Mission: Laboratory Access Protocol
Dr. B has left you three tasks to prove you’re ready to handle the laboratory’s most powerful analytical tools. Complete these challenges to earn your Laboratory Access Badge and begin your journey!
🔧 Challenge 1: Power Up the Laboratory (1 point)
“Every great analyst needs their tools ready!”
The laboratory’s main analytical engine needs to be activated. Load the tidyverse package to power up our data analysis capabilities.
💡 Hint: Think of this like starting up a powerful computer - you need to tell R which tools to make available!
[Same enhanced checking code as original, but with themed feedback messages]
💎 Challenge 2: Secure the Diamond Dataset (1 point)
“The diamonds hold the key to our mystery!”
Dr. B has prepared the legendary diamonds dataset for your investigation. Your task: secure it in the laboratory by creating a proper data object, then verify your security clearance with the ls() scanner.
💡 Hint: You’re creating a secure copy of the diamond data and then checking that it’s safely stored in your workspace!
💰 Challenge 3: Decode the Price Mystery (1 point)
“What secrets do the diamond prices reveal?”
Dr. B suspects there’s something unusual about the diamond prices. Use your analytical powers to calculate the average price and uncover the first clue!
💡 Hint: The mean() function is like a detective’s magnifying glass - it reveals the central tendency of the data!
🔍 Discovery Report: What is the average price of diamonds in your dataset? This number will be important for next week’s investigation!
📏 Challenge 4: Measure the Carat Clue (1 point)
“Size matters in the diamond world!”
Dr. B needs you to investigate the typical size of diamonds using the median() function. This will help establish baseline measurements for the ongoing investigation.
💡 Hint: While mean shows average, median reveals the “middle” value - sometimes more reliable when data has extreme values!
📐 Measurement Report: What is the median carat size? Record this crucial measurement!
