Find the quartiles of the list 45, 32, 67, 54, 34, 28, 78, 92, 95, 60. | |

We need to put this list in order: 28, 32, 34, 45, 54, 60, 67, 78, 92, 95 First we cut the list in half by finding the median. This list has two middle numbers: 28, 32, 34, 45, **54, 60**, 67, 78, 92, 95 Its median is . Now we look at the left half of the list (not including the median, which isn't in the list anyway): 28, 32, 34, 45, 54. and we find its median: 28, 32, **34**, 45, 54. Finally, we look at the right half of the list: 60, 67, 78, 92, 95 and we find its median: 60, 67, **78**, 92, 95. The quartiles are 34, 57, 78. | |
