In 1977 there is no reason for anyone to have a computer in their home . Our tendency to see the relaionship between 2 variables when there isn"t actually one. Thinking that does not blindly accept arguments and conclusions, examines assumpions, hidden values, evidence and conclusions. Theory: explanaion using integrated set of principles that organizes observaions and predicts behaviours or events. Hypothesis: a testable predicion, oten implied by a theory. Case study: technique where one person studied in depth. Naturalisic observaion- not manipulaing the situaion, observing nature.
