This writer has lifted a table from a secondary source and used it directly in his/her draft. By doing this, the writer has used another person's ideas, calculations and words without acknowledgement. This lack of citation constitutes plagiarism.
To eliminate this type of plagiarism, you should provide a citation for any tables, graphics, figures or images you acquire from secondary sources. You may also consider translating the information from tables into your own words. Remember, even if you use only information from a graph, chart, figure or image in your paper, you still need to acknowledge your source by providing proper citation.
