Document Summary
Naturalistic observation and behaviour sampling: naturalistic observation means you watch without the subject knowing that you are watching, watching behaviour as it naturally occurs, advantages, real world behaviors with no confounding variables, good external validity the observations you make and the conclusions you make are very relative to everyday life. Some variables are associated or correlated (e. g. height and weight: correlations range from 1. 0 to . 10, a positive correlation suggest that as one variable increases the other variable increases, a negative correlation suggests that as one variable increases the other variable decreases. Validity: what is being measured: content validity: shows if the items on a test sample the domain they are supposed to lectures and information found in the textbook, for example the content on the exam should only contain information discussed in the, criterion validity shows the relationship between a behaviour and the score on other relevant, construct validity does a test measure what it is supposed to measures.
