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

Reliability of the Media Growing up in America today means being exposed to numerous half truths. These are readily found on the television‚ newspapers‚ radio‚ and movies. The truth is hardly ever told in its complete form. Take for instance the local news broadcast‚ we watch it and take it for truth. We tend to give credibility to these newscasters based on the fact that they are representing major broadcast stations. These stations are supposed to be reliable and credible sources of

there are different ways to estimate reliability‚ it is necessary to provide a definition for the word reliability.” Reliability refers to the consistency of a measure. A test is considered reliable if we get the same result repeatedly. For example‚ if a test is designed to measure a trait (such as introversion)‚ then each time the test is administered to a subject‚ the results should be approximately the same. Unfortunately‚ it is impossible to calculate reliability exactly‚ but it can be estimated

Reliability Analysis Reliability analysis is an important component of engineering work that draws on the areas of probability and statistics. As the name suggests‚ reliability analysis is concerned with the investigation of the failure rates of components and systems‚ which are typically represented as probabilities. Life testing is a general term used to describe the experimentation and statistical analysis performed to investigate failure rates. Probability distributions that are used to model
