Reliability and validity are the concepts that help evaluate the quality of the research. They both are used in quantitative research to create a design, plan the methods and write the results. However, there is a major difference between reliability and validity.
The students usually get confused between these when it comes to writing the assignments in academic life. They can not differentiate and due to this, they can not do proper research for their topic. For this, they usually go for experts.
However, many students are still there who want to know the differences between validity and reliability on their own. For that, this blog is perfect for them. Here, they will know the differences in detail. But wait; before that, let’s understand both the terms in detail. So, let’s get started.
Reliability refers to a method that measures something in the level of consistency. If the same result is achieved by using the same method under exact circumstances consistently, it is called reliable. There are two key concepts that are indicated separately during the research. Those are:
However, when an error comes systematically, it does not affect reliability. Whereas, when a random error occurs, it leads to inconsistency in the results, which represents lower reliability. But it can be improved with the help of two ways;
As mentioned above, the reliability is estimated by comparing the different methods for the same measurements. So, the methods for estimation in reliability are split up into different types such as test-retest, interrater, and internal consistency.
Now, that you are very well introduced by reliability, let’s know about the validity.
Validity refers to the utility of statistics. It implies the extent of measures and what it is intended to measure. The research you do is high validity, which means the result corresponds to the real properties and characteristics. Therefore, the high reliability is an indicator that the measurement of the research is valid. On the other hand, if the method is not measurable, then it is not valid.
However, the reliability is not enough to ensure the validity of the research. For instance, if the test is reliable, it might not accurately reflect the scenario.
Moreover, reliability has its types. Similarly, the validity has been also split up into different types such as; construct, content, and criterion.
