The _____ method can be used to make researchers more confident about likely causal order.

A) correlational
B) experimental
C) field study
D) quasi-experiment

Experimental method allows researchers to manipulate the independent variable and observe the effect on the dependent variable. This helps to establish a causal relationship between the variables and makes researchers more confident about the likely causal order. The other methods such as correlational, field study, and quasi-experiment do not necessarily establish causality as they do not involve manipulation of independent variables.
