Use real data and precise language to work confidently with median class. In this lesson, focus on the median is the middle value after the data is ordered.
The median is the middle value after the data is ordered. It depends on position rather than the total, which makes it less sensitive than the mean to a very large outlier. For median class, the final written answer should make that exact relationship visible rather than hiding it inside an unexplained result.
Median class: The median is the middle value after the data is ordered. Count values on each side of the proposed median; the ordered list should balance around the centre. Keep the median class representation visible until the final line.
Drag values into order and highlight the central position or central pair. Use the model to explain one change you notice while working on median class.
Count values on each side of the proposed median; the ordered list should balance around the centre. Write that check beside the final median class answer.
Given information: Median class — Calculate 3 × 2 + 4. Method choice: Put the values in order before finding the middle. For an even number of values, find the mean of the middle pair. Calculation or reasoning: Use the given values with the stated relationship. Show the calculation clearly to obtain 10. Final answer: 10. Check: For an even number of values, find the mean of the middle pair.

Check: Check the median class result against the original information.
Given information: Median class — Calculate 3 × 13 + 9. Method choice: use the median class method and show each step with the stated values. Calculation or reasoning: Calculate 3 × 13 + 9. Final answer: 48. Check: substitute or compare with the original information to confirm the result fits the question.
Try explaining why each step works before checking the answer.
Given information: Median class — Calculate 3 × 12 + 4. Method choice: use the median class method and show each step with the stated values. Calculation or reasoning: Calculate 3 × 12 + 4. Final answer: 40. Check: substitute or compare with the original information to confirm the result fits the question.
Count values on each side of the proposed median; the ordered list should balance around the centre. Write that check beside the final median class answer.
