When we think about how to use numbers in Year 8 math, there are many everyday examples we can look at. Here are some that show how we use quantitative data:

1. Health and Fitness:

   • You might use a fitness app to track how many steps you take each day. The number of steps is a discrete quantitative variable because you can count each step separately, and you usually end up with whole numbers.

2. Weather Statistics:

   • Keeping track of the temperatures over a month gives us continuous quantitative data. For example, if it’s $20.5^\circ C$ one day and $22.3^\circ C$ the next, those numbers can be any value in between, showing that measurements can change.

3. Sports Analysis:

   • When looking at a basketball player's performance during a season, you can check how many points they scored in each game. These points are counted (discrete), and you can find averages to see how well the player did over time.

4. Class Grades:

   • Collecting information on test scores in class gives us quantitative data that we can use to see how everyone is doing. The average score helps us understand how well the class learned the material.

These examples make it clear why it’s important to know the different types of data. They help students see how statistics are used in real-life situations!
