Why was Dr. Sonabit's research rejected?A) the Hawthorne effectB) the placebo effectC) a positively skewed distributionD) sampling errorE) a negatively skewed distribution

D) sampling error

Explanation:A flawed research can be contributed to how a number of observations from a larger population, was  selected leading to produce either sampling errors or  non-sampling errors.

A sampling error is a statistical error that arises when an analyst fails to analyse a sample that represents the entire population of data giving rise to results that do not correspond to  the results that would be obtained from the entire population leading to a deviation in the analyst's sampled observation against the proposed true population.

Dr. Sonabit's manuscript was rejected by major publishers  because  her surveyed millennials living in Seattle, Washington, on political attitudes and emotional intelligence giving  her positive correlation between the two variables had sampling errors resulting from how her population was carried out in terms of not researching  a sample that covers the whole population of the millennials living in Seattle.
