posedly “expresses more than a thousand words” it robs the onlooker of the right to answer

32 Cross Tables (Statistics)

OpenOffice Calc is not in league with specialised statistics’ programmes like SPSS or its very

recommendable open source alternative PSPP. Nevertheless you can use it for statistical pur-

In a fictional survey we asked 12 people, men and women, to tell us on a scale from 1 to 10

how much they abhorred violent videos. The aim was to see if there was any significant vari-

ance between women and men. The raw results are listed in table 4, and the dependency table

appears in table 5.
