In science, experimenting is very, very important.
00:05
So we want to make sure that we experiment well.
00:09
And the first aspect of experimenting well is making sure that your experiments are all based off of a hypothesis.
00:16
And in order to have a solid hypothesis to experiment on, your hypothesis needs to be testable.
00:24
So clearly testable with measurable objectives.
00:30
And then your hypothesis also needs to be repeatable.
00:37
Now, science has gotten things wrong in the past many, many times.
00:41
And a lot of times we even think we get something right, and later it's proven wrong.
00:46
You can look at the nine people that have attributed the majority of our knowledge about the atom, right? it took us 2 ,000 years to understand the atom.
00:58
And for a long period of that, people believed what aristotle said, which was like, you know, all the things around us are not made up of atoms, but instead made up of the four elements like avatar las airbender, earth, wire, fire, air.
01:14
And so we have to be able to repeat experiments to prove something right or wrong again and again and again, because as we get new information, we can find out that previous assumptions are not correct.
01:29
And with this, we also need a null hypothesis.
01:35
So if not, then this.
01:38
So you have your hypothesis, which is what you believe should happen in the experiment.
01:41
And then you have a null hypothesis, which is, if i'm wrong, here's what we'll see instead...
