To design an experiment, the test the hypothesis, eating chocolate causes it.
00:07
So in order to design this experiment, the first thing that we want to do is make sure that we've determined all of the different components of experimental design.
00:18
So the first thing we're going to look at is our sample size.
00:22
So we want to make sure that we have a large enough sample that we're able to analyze our results for statistical significance and to eliminate any outliers.
00:33
So we'll say we have a sample size of 300 participants.
00:45
Our independent variables are the things that the experimenter changes and then measures the results of those change.
00:54
So in our case the independent variable is the dose of chocolate.
01:07
A dependent variable is what changes as a result of changing the independent variable.
01:14
So in this case we what we're going to be measuring after the dose of chocolate is the number and the severity of pimples that form.
01:36
Our standardized variables are the things that we need to normalize to ensure that the changes that we're seeing and that we're measuring are a result of the independent variable and not some external factors.
01:51
So one thing that we can do is to look at our sample points.
01:57
Population and make sure that there is normalized as possible...
