Georgina claims that the median is the best measure of center for this set of data she collected on hair length of her friends (in inches.) What is the median hair length? Write your answer in decimal form.
{10,26,14,12.5,13,11,12.5,14.1,11,8,14,12.3,11.4}
To find the median, first we need to reorder the data in ascending order:
{8, 10, 11, 11, 11.4, 12.3, 12.5, 12.5, 13, 14, 14, 14.1, 26}
The median is the middle value when the data set is ordered. In this case, there are 13 values, so the median is the 7th value, which is 12.5.
Therefore, the median hair length is 12.5 inches.
