The first extra activity for Week 0 has two parts:
Activity 1: Create a Google Site as a student portfolio with Statistics 2 as one of the pages inside it. Provide a short and relevant description about the course in this page.
Activity 2: Collect data from an interesting source and populate a Google Spreadsheet. The data should have minimum of 100 rows and 5 columns. Describe the rows and columns of this data in your own words and describe something interesting that you learnt/observed from this data.
Here is the solution to the activity:-
Description of Data Provided:
The data shows daily air quality measurements (AQI) for different cities worldwide. Each row includes the city, country, date, AQI level, and the air quality category (e.g., "Good" or "Unhealthy").
Cities like Tokyo and Sydney often have "Good" air quality, while Delhi and Beijing frequently have "Unhealthy" levels.
Air quality fluctuates in some cities (e.g., Cairo and Mexico City) between "Moderate" and "Unhealthy for Sensitive Groups."
High AQI levels in cities like Delhi indicate serious health risks, especially for sensitive groups.
