[Informatics] Hypothesis examples

[Mark]

Good ideas, Jordyn!

These examples also reinforce the need for causation to be specified in the
hypothesis, in the form of
"<dependent variable> because <independent variable>" or
"<independent variable> causes <dependent variable>"

Otherwise kids might simply pose a research question such as,
"Sales of cheese are correlated with national heart attack statistics"
or
"The number of magpies is decreasing and the number of crows is increasing."

Cheers
