Median data set quiz for 7th graders

📚 Quick Study Guide

• 🔢 The median is the middle number in a sorted list of numbers. Think of it as the number that sits right in the center!
• 📝 To find the median, first, you need to arrange your data set in ascending order (from smallest to largest).
• 📌 If you have an odd number of values, the median is simply the middle value.
• ➗ If you have an even number of values, the median is the average (mean) of the two middle values. You find this by adding the two middle numbers and dividing by 2: $\frac{number1 + number2}{2}$
• 💡 Remember to always sort your data first! That's the most important step.
