Catatan

Many behavioural and social science students (and researchers for
that matter) despise statistics. Most of us have a non-mathematical
background, which makes understanding complex statistical
equations very difficult. Nevertheless, the evil goat-warriors of
Satan force our non-mathematical brains to apply themselves to
what is the very complex task of becoming a statistics expert. The
end result, as you might expect, can be quite messy. The one
weapon that we have is the computer, which allows us to neatly
circumvent the considerable disability of not understanding
mathematics. Computer programs such as IBM SPSS Statistics,
SAS, R and the like provide an opportunity to teach statistics at a
conceptual level without getting too bogged down in equations.
The computer to a goat-warrior of Satan is like catnip to a cat: it

makes them rub their heads along the ground and purr and dribble
ceaselessly. The only downside of the computer is that it makes it
really easy to make a complete idiot of yourself if you don’t really
understand what you’re doing. Using a computer without any
statistical knowledge at all can be a dangerous thing. Hence this
book.
