Reliability vs validityMore often than not, reliability measures the number of times the research results stay the same when research gets done multiple times. Note that when conducting the research repeatedly, you have to do it under the same conditions. On the other hand, validity checks if the research results measure the exact estimate provided by reliable sources. When assessing reliability, you need to repeat the survey under the same conditions. Then, check whether the results are the same across the different surveys. If you evaluate the validity, you need to compare your research results with proven theories and statistics. Check whether they are communicating the same concept. Reliable research results are not always correct, even though they are reproducible. Valid research results are accurate; thus, they are reliable. Researchers should always aim for valid research results.
Making sure you obtain validityWhen conducting research, it is important to attain accurate results. Your results should be a reflection of real-life situations. This way, people will be able to relate to your final reports. Below are some of the methods you can make sure you ensure your research results have excellent validity.
1. Select the right methods of measurementIf you want to obtain validity in your research results, you have to employ the right measurement techniques. Incorporate high-quality research methods that guarantee 100% accuracy. So, how do you find the best research methods? You can look up the best research methods online and check whether they meet your requirements. Alternatively, consult a research expert on the best measurement methods to employ. For instance, if you want to obtain information about an individual’s personality, use a questionnaire with valid questions. Some of the questions you can include in the questionnaire include:
- Would you consider yourself a generous person? (Measure yourself from a scale of 1 to 5)
- Do you find yourself being a team leader in groups?
- Do you feel the need to stand up for others when they are being overlooked?
