Paper 22 Q3(b)IGCSE 0580 May/June 2023

Question

On ten days, Stefan records the number of minutes he has to wait for a train. 1 3 12 5 4 23 5 24 11 8 Find the median.

This question tests your ability to find the median from a set of data. The median is the middle value when data is arranged in order, and it's a key measure of central tendency in statistics.

Step-by-Step Solution

Key Takeaway

When finding the median with an even number of values, you must average the two middle values after arranging the data in order.

Common Mistakes

Not arranging the data in order first - you cannot find the median from the original unsorted list
Taking just one of the middle values instead of averaging both when there's an even number of data points

Exam Tip

Always count your data values first to check if you have an odd or even number - this determines whether you take one middle value or average two.
