Put the given data in ascending order:
1, 1, 1, 1, 1, 2, 3, 3, 3, 3, 5, 9, 9, 9, 9, 9, 9, 9, 9, 9Mean is the average of 20:
(1*5 + 2 + 3*4 + 5 + 9*10)/20 = 5.7median = 5.7Mode is the most repeated number:
mode = 9Median is the average of the two middle numbers:
(3 + 5)/2 = 4median = 4Ответ:
Mean = 5.7
Median = 4
Mode = 9
