The median is found by putting the numbers in order from least to greatest and finding the
number in the middle. The lower extreme is found by identifying the lowest number on the line
which is “1”. The upper extreme is the highest number on the line which is “12”. To find the
lower quartile you first need to identify the median from the first half of the number line which
is “2”. The upper quartile will be the median of the second half of the number line which is “6”
