Document Summary
The goal of empirical research is to explain variation with respect to the dependent event. Within a case there is always variation which we want to explain. Are not casually related but, both are caused by a third variable. Least likely way to test causality increasing the number of cases. Quantitative research relies on probability statements of to establish the boundaries of its conclusion, while qualitative research reports the plausibility of its findings. The regression line provide a best prediction of the dv scores for any given iv score. 27% of the variation in y can be explained by x. When conducting a multiple regression analysis it is important to begin by generating a correlation matrix. There is a 5% chance the relationship happened by chance. A 95% confidence level is less rigorous than a 99% confidence level. T(cid:455)pe i error are (cid:373)ore likel(cid:455) if . When we adopt a lower confidence interval.
