Ready to learn? Then let’s begin with an overview of both the terms.
Reliability And Validity: A General Overview
Both the concepts seem similar but are somewhat different from each other. Many students have the question “what is reliability and validity?”. Well, to understand these topics deeply, let’s define both of them individually:-
What Is Reliability In Research?
In simple words, the extent to which you can rely on something is called reliability. If we take them in technical terms, it is defined as the extent to which a single result can be reproduced again under the same conditions. One is said to be reliable if things turn out the same every time the information is verified.
What Is Validity In Research?
Validity is the measure of accuracy that it holds. For any information to be used in a document, you have to be one hundred percent sure that it is valid and does not compromise in any way. In technical terms, it is a measure of accuracy to the extent to which it is supposed to measure something. Confused? Well, keep reading, as things will be explained further.
These are the textbook definitions of the terms, and both seem similar as they equally impact the quality of the content, which might hamper the credibility of your document. One of the fascinating things about both these concepts is that they are related to each other. How? Let’s find out.
Interdependence of these two
Well, for starters, if something is valid, it is also reproducible, meaning if an answer turns out to be accurate, it can be re-derived under the same conditions, which means if something is valid, it is also reliable.
On the other hand, if something is reproducible, it does not mean that it is correct. There are times when you make mistakes during a calculation, and the answer is derived from wrong calculations. The same can be derived again if the same mistakes are introduced but that will not make the outcome valid. It means that it is not necessary that if something is reliable, it also has to be valid.
Our experts express reliability and validity as one of the most confusing ones as the terms are also used in our daily lives, but still, some differences are visible! There are some differences in these concepts, and all of them show a specific trait for the content. Check them out in the next section.

What is the Difference Between Reliability and Validity?
Now that you are familiar with reliability and validity. Let’s jump into more detail, and highlight a few differences between the concepts and understand the fundamental boundaries that one must keep in mind while introducing validity and reliability in their research.
Key Aspects of Reliability:-
- It is the degree to which any result can be reproduced. In other words, the extent to which an outcome can be replicated again and again under the same conditions.
- There is no relevance of reliability when it comes to the evaluation of a multi-item scale.
- Finding out the reliability of any outcome is much easier.
- The aim of reliability is to measure consistency in a system.
- It is not necessary that a reliable system is also valid.
Key Points that Define Validity:-
- It is the proof of measuring something accurately. You can say that it is a measure of measuring. For instance, a pH scale can measure the acidic and basic nature of any liquid. Now, whether that scale is measuring accurately or not will decide if it is valid or not.
- Validity plays a key role in the evaluation of a multi-item scale.
- The assessment of validity can get troublesome.
- The aim is to check whether the results generated by a test are accurate and valid to use.
- An instrument or test that is valid will always be reliable.
Reading all the above points, you might have got clarity about the key difference between reliability and validity. The experts suggest that you note down all these or bookmark the blog to use the contents for later references when you are working on your thesis or any other research. For any research, you should always keep in mind that there are no chances, you have to be accurate in the first go, and thus reliability and validity are crucial factors that are needed to be discussed.
