Answer: 1
Step-by-step explanation: You can do this by writing it all out.
The frequency tells you how many of the number there are.
Eg. there are 9 0s because it says it on the table.
So you would write
0,0,0,0,0,0,0,0,0,1,1,1,1,1,2,2,2,2,2,2,2,3,4,4,4
Cancel one number from both sides going into the middle until.
Median = 1
