scientific reliability and validity. Reliability focuses on the consistency and stability of measurement. There are pros and cons to obtaining reliable measurements. One way to test reliability in a measure is to perform the same test on the same population multiple times which is called reliability coefficient (Branson‚2014). Another way to test reliability is by randomly splitting test questions in half‚ administering‚ then look for consistencies‚ which is called split-half reliability (Feinberg

Validity refers to truth and accuracy when it comes to dealing with research. Validity and reliability go hand in hand with each other‚ one depending on the other is some aspect or another. There are many different types of validity that researchers can use‚ as well as‚ methods used for measurements. Having so many available options leaves validity vulnerable for threats concerning the research. The main threats concerning validity are: self-selection effects‚ volunteer effects‚ attrition‚ history

The test yields dependable scores that is if the scores do not fluctuate very much the test is reliable. means the scores obtained by a student will be close to the score she

Discuss potential challenges to validity and reliability of your research question‚ data‚ and analysis. Validity and reliability are the backbone of what is accepted as scientific proof by researchers. Potential challenges to reliability of a research question‚ data‚ and analyses are any significant results must be repeatable. Anyone who wanted to perform the same experiment applying the same conditions should arrive at the same result. If this is successful this reinforces the results
