3.3 - Analysing Data to Identify Patterns
The importance of checking information for reliability
When researching, especially online, it is essential to analyse the data and information you find. This helps ensure that what you use is accurate, current, and free from bias. Relying on poor-quality information can lead to wrong conclusions or decisions.
Why reliability matters
- Inaccurate details might include errors or false claims that mislead you.
- Out-of-date content could refer to old facts that no longer apply, such as outdated technology or prices.
- Biased information presents a one-sided view, often to promote a specific agenda, like a company praising its own product.
Failing to check these aspects can affect your work, such as in school projects or when making choices like buying software.
Challenges with information on the Internet compared to print media
Not every piece of information is trustworthy, and spotting reliable sources can be tricky. The Internet poses unique issues, but it also has advantages over traditional print media.
Key challenges on the Internet
- Anyone can publish content without checks, so unreliable or false information is common.
- It is often hard to separate high-quality sources from low-quality ones, as they might look similar.
Advantages and disadvantages compared to print media
- Internet advantages - Websites can be updated quickly and easily, allowing corrections or new details to be added at any time.
- Print media disadvantages - Items like books or magazines are fixed once printed, so mistakes cannot be fixed without a new edition, and they may become outdated faster.
When using any source, always question its origins and freshness to avoid using flawed information.
Using the Do CRAB method to evaluate sources
To find useful and reliable information, apply the Do CRAB method. This is a checklist that helps you assess sources systematically before using them.
The Do CRAB evaluation criteria
| Criterion | Questions to ask |
|---|---|
| Date | When was the information created or last updated? Is it still current, or could it be outdated? |
| Clear | Is the information easy to understand? Avoid using content that is confusing, as it might not suit your audience either. |
| Relevant | Does the information directly relate to what you need? Ignore details that do not fit your purpose. |
| Authors | Who created the information? Are they qualified experts in the topic, or do they lack credibility? |
| Bias | Is there any reason the authors might be one-sided? For example, a company could overstate the benefits of its own product to boost sales. |
Using this method ensures your sources are suitable and trustworthy.
Applying evaluation criteria to real examples
To see how evaluation works in practice, consider scenarios where you apply the Do CRAB method.
Example: Evaluating a product review
Imagine a student named Faye is researching flight simulators to buy one. A flight simulator is software that recreates the experience of piloting an aircraft. She finds an online review for a product called FlightSimSuper.
How the review might be evaluated using Do CRAB:
- Date - The review was written on 25/09/2008, which is over 15 years old. Newer simulators might be better now, so this is outdated.
- Clear - It uses technical terms like "spatial anti-aliasing" (a method to improve graphics smoothness), which might be confusing or not important for a beginner.
- Relevant - The review is about a flight simulator, so it matches Faye's needs for information on this type of product.
- Authors - The writer is Marc, who created FlightSimSuper, so he is not an independent expert.
- Bias - As the creator, Marc is likely biased, exaggerating how great the product is (e.g., calling it "the best ever") to encourage sales. The review promotes buying it and mentions its low price of £75.
Overall, Faye should not rely on this review to decide on her purchase. While it is relevant, the bias and age make it unreliable. She would be better off finding recent, neutral reviews from trusted sources.
