8. Option B,Replication is a term referring to the repetition of a research study, generally with different situations and different subjects, to determine if the basic findings of the original study can be applied to other participants and circumstances. 9.Survey method,a telephone survey is a method of public opinion polling where telephone numbers are used to contact potential respondents, either from the general population or from a known sample. 10.Naturalistic observation,it is a research method commonly used by psychologists and other social scientists. This technique involves observing subjects in their natural environment. 11.Correlational;It is just a linear association between two variables, meaning that as one variable rises or falls, the other variable rises or falls as well. 12.Positive correlation,it is a relationship between two variables in which both variables move in tandem. A positive correlation exists when one variable decreases as the other variable decreases, or one variable increases while the other increases. 13.Negative correlation;In this, the variables move in inverse, or opposite, directions. In other words, as one variable increases, the other variable decreases. 14. -1 indicates a strong correlation.The strongest linear relationship is indicated by a correlation coefficient of -1 or 1. The weakest linear relationship is indicated by a correlation coefficient equal to 0.
