The following key points should be considered when authoring the background section. Explain research questions and purpose in lay language. Define or explain research terms like "randomization" or "double-blind." Use declarative sentences suited for an eighth-grade reading level. Keep the description as brief as possible. Give some indication of previous work done in the area. Include key elements of the research process. Include the duration of the study. Give enough information to make an informed decision, but not so much (or so technical) that the subject becomes confused. Describe all quantities with lay term equivalents, i.e., teaspoons.
