Sample: the first question, solved
A frequency table shows: Apple=12, Banana=5, Orange=3 (20 total). What can you conclude about fruit preferences?
And one from the hard end
Two bar graphs compare the same school's attendance data: Graph G's vertical axis uses intervals of 1 (making a 3-student difference look dramatic), Graph H's axis uses intervals of 50 (making the same difference look tiny). A parent looks only at Graph G and concludes attendance is "wildly inconsistent." Which statement best evaluates this conclusion?
