1. Title "Selective Reporting and Misrepresentation of Data" Subject: Research and Publication Ethics Presented By Abhishek Garg ECE

2. Introduction Selective Reporting and Misrepresentation of Data S elective reporting and misrepresentation of data can have serious consequences, as they can lead to false conclusions, misguided policies, and flawed decision-making . It is important to use reliable sources and to critically evaluate the information presented to ensure that it is accurate and unbiased.

3. Selective Reporting Selective reporting refers to the act of intentionally presenting or omitting certain information, data or results in a biased manner to support a particular viewpoint, hypothesis or conclusion. This can be done by presenting only the information that supports a particular argument or by ignoring information that contradicts it.

4. Types of Selective Reporting:- Publication bias: This occurs when studies with significant or positive results are more likely to be published than studies with non-significant or negative results. This can lead to an overestimation of the true effect size and can skew the scientific literature . Outcome reporting bias: This occurs when only certain outcomes of a study are reported, while others are not. This can occur when the reported outcomes are more favorable to the author's hypothesis or agenda. Data dredging: This occurs when multiple statistical tests are performed on a dataset to find significant results, even if the results are not meaningful or relevant. This can lead to false-positive results and can be a form of data manipulation. Spin: This occurs when the presentation of the results is biased or slanted towards a certain interpretation or conclusion, even if the data do not fully support it. This can be a deliberate attempt to manipulate the reader's perception of the results. Selective citation: This occurs when only certain studies or sources are cited to support a particular argument, while other relevant studies or sources are ignored. This can be a form of cherry-picking data to support a particular viewpoint.

5. Misrepresentation of Data It refers to the manipulation or distortion of data to create a false or misleading impression. This can be done by selectively choosing data, altering or omitting data points, or presenting data in a way that obscures the true meaning or significance of the information.

6. Types of Misrepresentation of Data Data falsification: This occurs when data is intentionally altered or fabricated to support a particular hypothesis or conclusion. This is a serious ethical violation and can have severe consequences for the individual and the organization involved. Data cherry-picking: This occurs when only certain data points are selected or highlighted to support a particular conclusion, while other data points are ignored or de-emphasized. This can lead to a biased or incomplete picture of the overall data. Data manipulation: This occurs when data is manipulated or adjusted in a way that alters the conclusions that can be drawn from it. This can include changing the scale of the axis on a graph to make differences appear larger or smaller than they actually are. Data misinterpretation: This occurs when data is presented in a way that is misleading or misinterpreted. This can include presenting correlation as causation, or failing to acknowledge alternative explanations for the data. Data omission: This occurs when relevant data is left out of a report or analysis, either intentionally or unintentionally. This can lead to an incomplete or inaccurate picture of the overall data.

7. How to Avoid Selective Reporting and Misrepresentation of Data Ensure transparency: Be open and honest about the data being presented, including any limitations or weaknesses. This can help to avoid the perception of bias or manipulation. Avoid cherry-picking: Present all relevant data, even if it does not support the hypothesis or conclusion being tested. This can help to ensure that the overall picture is not skewed. Use appropriate statistical methods: Ensure that appropriate statistical methods are used to analyze the data and that the results are presented in a way that accurately reflects the data. Verify data sources: Verify the data sources and ensure that they are reliable and accurate. This can help to avoid errors or biases in the data. Use independent review: Have the data and analysis reviewed by independent experts to ensure that the conclusions are sound and unbiased. Follow ethical standards: Adhere to ethical standards and guidelines for data reporting and analysis, including those set forth by professional organizations and regulatory bodies. Acknowledge limitations: Be transparent about the limitations of the study or analysis and acknowledge any potential sources of bias or error. This can help to ensure that the data is interpreted accurately and responsibly.
