4. What are the modes of 7.7, 8.4, 6.3, 7.0, 6.4, 7.0, 8.6 and 9.1 The median is The average is__ ．

Data from small to large order is 4, 6.3, 6.4, 7.0, 7.0, 7.7, 8.4, 8.6, 9.1, a total of 9 data, so the median is: 7.0; data 7.0 appeared twice, the most times, so the mode is 7.0; average: (4 + 7.7 + 8.4 + 6.3 + 7.0 + 6.4 + 7.0 + 8.6 + 9.1) △ 9, = 64.5
