For an emperical research project discuss the method of experimentation. Summarize the results of the experimentation or research. Include tables and figures if appropriate. If a great deal of data is collected, summarize the results and include relevant raw data in an appendix. Figures are graphic illustrations of things or data.
Tables are arrays of data with headings to identify the entries.
Reference facts which are not common knowledge or opinions of others. Include secondary data such as raw data. Don't include figures and tables. They belong in the text. When tables and figures are oriented lengthwise, the bottom should be toward the night.
