To find the median of the list 1, 9, 4, 3, 7, 6, 8, 8, 12, 15, first, arrange it in ascending order: 1, 3, 4, 6, 7, 8, 8, 9, 12, 15. With an even number of values, the median is the average of the two middle numbers. Here, that's 7 and 8, making the median 7.5.

FAQs & Answers

  1. What is the median in statistics? The median is the middle value in a data set when the numbers are arranged in ascending order, dividing the data into two equal halves.
  2. How do you find the median of a list with an even number of values? When there is an even number of values, the median is found by averaging the two middle numbers after sorting the list in ascending order.
  3. Why is median important in data analysis? Median provides a measure of central tendency that is less affected by outliers and skewed data compared to the mean, making it useful for understanding the typical value of a dataset.
