What methods do we use to study human behave? The first technique is called naturalistic observation,
which is essentially just seeing what happens. (Obtrusive measures or non-interactive measures), not
intruding in a way that might get in the way of responses and behaviours.
The second way of observation is case study. This means deep study of a single individual (N=1). Get data
from many different resources to try and get some understanding of why the individual may be suffering.
You can make predictions from surrounding environment. You cannot generalize principles of behaviours
from a big group.
The third is the study of correlation (r)-the relationship between two variables. And the greater the
correlation, the greater predictability of the outcome. Correlation spans from -1and 1. Variance
