If you're using a number such as a statistic from a reference study you want to cite, should you write the number with the confidence interval? And how to effectively prevent plagiarism when dealing with numbers?
Iltimass Gouazar when you’re citing statistics from a reference study, it’s generally a good practice to report the confidence intervals as well. Including them adds context to the statistic and gives a sense of the uncertainty or variability associated with the estimate. However, to prevent plagiarism, you do the needful which is to cite each of your sources and paraphrase using your own words.
As per my understanding mentioning figures/statistics of others' articles in the process of discussion/comparison to substantiate or refute our findings is possible since we recognize the source of evidence through citation.
