Web Science/Part2: Emerging Web Properties/How big is the World Wide Web/An unrealistic, simplistic generative model/quiz

1 Why is formulating a hypothesis so crucial in the process of scientific modelling?

	Formulating a hypothesis clears the path towards a clear defined model
	Often simplifying assumptions are knit into the hypothesis and the afterwards built model

	true
	False

3 Why should one have several runs of a generative probabilistic model?

	in the first run the caches need to warm up
	to get statistic stability
	because random experiments can produce strong outliers in just one run
	there is no cost of making sure the computer did correct calculations by running the experiment twice or more
	because every scientific experiment should be repeated more than once to avoid mistakes
