comment What is the meaning of the y-axis on graph that show's “difference”?
Why would a published paper be so unclear? I'm not asking out of sarcasm, I've noticed a lot of papers like this. Isn't it to the author's benefit to be clear?

OK so there is an average star rating for an item for the novice group AND an average star rating for an item for the expert group? And the y-axis show's the difference between the two?

For 1 that would make sense if the graph had -3 and not -0.3. What is it the values are off by a scale factor of 10?

@BrianO could you elaborate what you mean by prefixes? So if $L=\{000, 101\}$ then $L'=\{0, 00, 1, 10\}$?

comment Need help understanding question about how many languages can fit set?
Ok I see my confusion. From here "the language accepted by a DFA is the set of strings accepted by the DFA." does this mean the language must include every possible string that is accepted by the DFA?

Thanks I get it. I may misunderstand what a language is. Isn't it the set of all strings that lead a DFA from a start state to final state, not a subset of this (such as your explanation implies)?

oh right because each digit can be $0$ or $1$ and there's $n$ of them so $2^n$ ways. Thanks.
