(Q4). Does the mode change, if another observation is added to the data in Example? Comment.

Answer :

In the example the observations are 0, 1, 2, 2, 2, 3, 3, 4, 5, 6.

Here mode

3
6
2
2,3

If we add '2' then mode doesn't change.

If we add '3' then the mode will be

2
3
2 and 3
6

Even if we add other then 3 the mode will not be changed.

True False

So we cannot decide whether the mode changes or not. It depends on the situation.
