Answer:
Sum of numbers =7+4+3+5+6+3+3+2+4+3+4+3+3+4+4+3+2+2+4+3
+5+4+3+4+3+4+3+1+2+3
=104
Total numbers are 30
mean=
30
104
=3.46667=3.47
The mode is the number which appeared most.
Therefore, mode=3
For median arrange the numbers in ascending order:
1,2,2,2,2,3,3,3,3,3,3,3,3,3,3,3,3,4,4,4,4,4,4,4,4,4,5,5,6,7
Median =
2
(15
