OVERVIEWOVERVIEW

Although the second major section Although the second major section of the experimental research of the experimental research report is often called “method”, it is report is often called “method”, it is some times titled some times titled materials and materials and method.method.

This combined title indicates that This combined title indicates that researchers generally describe researchers generally describe these two aspects these two aspects togethertogether when when they write up their research. That they write up their research. That is they simultaneously describe is they simultaneously describe any equipment or other any equipment or other materials materials they used with each step in their they used with each step in their procedure.procedure.
