🤔 Why Use a Plagiarism Checker?

The issues of plagiarism and academic dishonesty become more and more relevant each year. According to some research, 92% of surveyed students stated that they had or knew someone who had cheated.

Some students will cheat if given a chance.

So, why does this happen?

The researchers have shed light on this phenomenon, and here are some of their statistics:

  • 92% of those who plagiarized stated that they did so because they wanted better grades.
  • 83% said that they cheated because of procrastination.
  • 75% of respondents pointed out that they did not have enough time to finish their assignments.
  • 33% have attempted to cheat due to their overloaded class schedule.
  • 58% of the surveyed have plagiarized because they lacked an understanding of the subject.
  • 50% had little or no interest in the subject.
  • 25% of participants believe that anyone can cheat without any consequences.
  • 17% of the interviewees cheated because of peer pressure.
  • Another 17% think that it does not matter to the professor if their paper is plagiarized.

After taking all of these numbers into account, it is evident that a significant percentage of students commit acts of plagiarism for several main reasons. Among them are poor time management, concern for academic performance, and peer pressure.

✏️ Common Types of Plagiarism

Now that you know the causes of plagiarism, it will be beneficial to examine its different types. Generally, these can be divided into two groups: unintentional and intentional.

Intentional Plagiarism

When it comes to intentional plagiarism, it doesn’t necessarily mean that your paper copies the full document written by someone else. This is only one example of cheating out of many others.

Some plagiarism types can lead to serious sanctions.

Unintentional Plagiarism

Meanwhile, unintentional plagiarism may refer to:

  • Forgetting to cite a source when describing something that is not common knowledge.
  • Not citing information that you have paraphrased or summarized.
  • Failing to use a proper citation style when documenting sources.
  • Misquoting an author, even if it is appropriately cited in the paper.

When composing your paper, it is important to stay vigilant. This is why it is handy to utilize the help of our plagiarism checker (2000 words). Free detection software is a quick and easy way to confirm your paper’s originality.

🔍 How to Check for Plagiarism

As you work on your paper, you may start to ask yourself: How can I avoid plagiarism altogether?

How to avoid plagiarism in 5 steps.

Below, we have prepared some tips that will help you write a 100% original essay:

  1. Regulate your time. As mentioned earlier, procrastination and a full class schedule may lead to plagiarism. To stay on top of everything, don’t put off urgent tasks until tomorrow. Read up on time management techniques and figure out an efficient study method that works for you.
  2. Cite while you write. Get in the habit of citing sources in full as you write your paper. Firstly, doing this will save you plenty of time for putting together a bibliography. Second, it will significantly decrease the risk of an improper citation.
  3. Use only trusted sources. There are a lot of websites with questionable content. Even documents that seem scholarly at first could turn out to be another student’s paper. Ascertain that you understand the source and the ideas that it is trying to convey.
  4. Understand the difference between various citation styles. An improper citation may result in a penalty for plagiarism. So, make sure you rely on a high-quality reference guide and implement the correct style. Don’t forget to add quotation marks when using unchanged phrasing from the source.
  5. Use plagiarism scanners before you submit your paper. Even if you wrote your piece from scratch, we still advise you to double-check it. From time to time, you might unintentionally “borrow” a couple of phrases that appear in other works. Despite it being an accident, your professor might penalize your paper. To avoid this, you can use one of the online free plagiarism detectors.
