Fact 3 from Video 3: Biased sampling methods: Convenience Sample, Voluntary Response Sample
Fact 4 from Video 4: You can't have a valid inference without a representative sample
Fact 5 from Video 5: To make samples more realistic, you can take the mean of different samples.
Fact 6 from Video 6: You can inference the outcome for a population by multiplying the sample.
Good Job!
