Plagiarism statistics calculation


Statistics, including plagiarism statistics, serve as valuable tools for highlighting differences between countries across various metrics such as tax rates, crime rates, and alcohol use. Each of these categories has its own set of methodologies for data collection and calculation. The question of how the rate of plagiarism is measured is particularly relevant, given the serious academic, legal, and professional implications associated with it.

Understanding the assessment standards for plagiarism is crucial for accurately interpreting these statistics and for devising effective strategies to address the issue.


Methods for obtaining plagiarism statistics

There are at least 4 different acknowledged scientific methods for calculating the unemployment rate. Likewise, there are also several different ways to collect plagiarism statistics:

1. Plagiarism survey

In this method, surveys are administered to students or teachers to inquire about their practices. The questions typically include:

  • Do you plagiarize?
  • Do you know someone who has plagiarized?

While these surveys offer insights into everyday academic behavior, they come with several vulnerabilities. For example, respondents may not be honest about their plagiarism activities. Additionally, gathering this type of data can be costly.

2. Penalties for plagiarists

Some universities offer statistics on the number of students caught for plagiarism. When these figures are combined at a national level, they can provide insights into how widespread the issue of plagiarism is. This method carries similarities to the one used for calculating rates of smuggling. With this approach, certain limitations exist:

  • Differences in implementation. The percentage of revealed violations could differ between countries or even universities. One institution may have strict guidelines on plagiarism, while another may be more soft.
  • Lack of transparency. There is also the possibility that some universities may attempt to cover up plagiarism scandals, opting to publicize only extreme cases.
  • Incomplete picture. The number of plagiarists caught by educational institutions may not accurately reflect the true degree or overall commonness of plagiarism.

Given these limitations, the statistics collected using this method may not fully catch the real scope of plagiarism.

3. Polls concerning tolerance of plagiarism

Some researchers perform questionnaires with inquiries such as, “Do you think plagiarism is always bad?” It’s commonly thought that plagiarism statistics are directly connected to public opinions about plagiarism. Interestingly, there are always some students who argue that plagiarism is sometimes acceptable, believing they have valid reasons for this position. However, it’s important to differentiate that tolerance of plagiarism is not the same as participating in plagiarism itself.

4. Plagiarism checker statistics

Internet tools for checking plagiarism offer a wealth of data, providing insights that can be invaluable for understanding the scope and nuances of plagiarism. These tools offer the following types of information:

  • The number of uploaded documents containing plagiarism.
  • The average percentage of plagiarism detected within those documents.
  • The probability of plagiarism in specific documents.

A strong plagiarism checker may even present accurate national plagiarism statistics. Some checkers, like ours, operate internationally, offering their services across various countries. The most significant advantage of such international systems is their ability to provide similar data across different countries. This is made possible because all the data is collected using consistent methods, making it
possibly the most accurate way to assess global plagiarism rates.
