Short response: A group of researchers is running a randomized control trial in Mexico, where they are studying the link between development projects and public support for government forces. They are randomizing which villages in one district receive a development project (for example, an irrigation system) and which receive a control condition (no project). Assume that the researchers have gathered information about village characteristics prior to the trial. Question: Name and describe at least one other potential source of bias (not mentioned above) in this RCT. You may make up facts.

Types of Bias

Statistics is the study of data collection, organization, analysis, interpretation, and presentation. Statistical bias is a characteristic of a statistical technique or its findings in which the expected value deviates from the actual root quantitative parameter being estimated. According to the actual definition of bias, it refers to the tendency of a statistic to overestimate or underestimate a parameter.
