Reliability in science
Reliability offers importance in psychological experiments such as quality of measurement this is defined as the extent to which you can measure a participant’s true score, it is something that every scientist must be aware of, especially in social sciences and biological experiments. True score is defined as a person’s general ability to take part in a study to their full potential. Reliability is also how repeatable the experiment is… is this really important when it comes to scientific tests, and why?
Reliability is important when it comes to scientific tests, it is essential for experiments to have a measure of quality so that other psychologists can carry out the tests again and investigate whether their results correspond to those that have been published, the consistency of the experiment must be maintained, a researcher must use as many repeat sample groups as possible, to reduce the chance of an abnormal sample group skewing the results. For example, if you use the same samples in each manipulation of an experiment and one generates results that are completely different from the others, then you know that there may be faults within the experiment, this is also where pilot studies can be useful, as a smaller scale experiment can reduce the amount of abnormalities found in the proper experiment as these have already been altered.
In relation to the real world, reliability is essential when it comes to competition of products being sold, if a company presents something about their product which makes it stand out from the rest of the competition, and this is then proven to be wrong, the company loses the reliability it has been working so hard to gain, negative customer satisfaction also loses reliability as they will not give positive feedback to others. Their reputation will also be lost, as customers will go to companies whose products have never failed in reliability.
In conclusion, I believe that reliability is essential in scientific experiments and is something that all scientists do and should take into consideration within their experiments. Through research I have seen that reliability is also important within the consumer world, if a company or product lacks reliability then this can discredit their product and make it less sellable to the public.
