Is it true or false that a dataset will always have exactly one mode? so i'll start with the answer.
00:07
This is false.
00:10
Let's look at why.
00:12
So the mode is the most frequent value in your dataset.
00:18
So there are a few options.
00:20
You could have no mode at all.
00:23
This happens if every review has the same frequency.
00:27
So all have the same frequency.
00:31
I'll give an example.
00:32
The dataset, 1, 2, 3, 4.
00:41
They all have a frequency of 1, so there is no mode for that data set.
00:48
You could have 1 mode.
00:50
So this is where there's a single value that appears most often, and this all have a lower frequency...
