Document Summary

Have to yield a design of a study to collect proper data. This is how we think about issues, must remember to do the research clearly. Smaller groups, very in depth info i. e mass murders- going to the jail and interviewing. Social desirability (eg beer consumption) (say something they want people to believe they do/believe) Describes the strength of the relationship between 2 variables (r) is the symbol for this. R= +. 20 or r= 0 or r= -. 50. Neg. does mean less than but rather go in opposite directions. Depressed people have low self esteem this is a neg. correlation. A third (hidden) variable can account for the relationship between 2 variables. Most powerful research method to detect casus and effect relationships. Could be sleep deprivation and how it causes aggression- the thing that is changed and manipulated to get an outcome. The end result- the thing that stays the same.
