Answer: data is faked or is misplaced it is said to be HACKED.

What does the doctor tell Phaedra that she has discovered quizlet?

What does the doctor tell Phaedra that she has discovered? The doctor tells Phaedra that she had a hallucination of the statue 3.

What is a reason that these data may be unreliable quizlet?

What is a reason that these data may be unreliable? It is information that is too new to be considered factual. It was found on the American Cancer Society website, and websites are unreliable. It is information that is used for a variety of purposes and not just gathered for research.

What is the relationship between reliability and validity?

Reliability (or consistency) refers to the stability of a measurement scale, i.e. how far it will give the same results on separate occasions, and it can be assessed in different ways; stability, internal consistency and equiva- lence. Validity is the degree to which a scale measures what it is intended to measure.

What is the relationship between reliability and validity quizlet?

What is the difference between reliability & validity? Reliability: The test measures one and only one thing (precisely). Validity: The test measures what it is supposed to measure.

What does reliability reveal about a study quizlet?

Reliability in assessment refers to the confidence that can be placed in an instrument to yield the same score for the same student if the test were administered more than once and to the degree with which a skill or trait is measured consistently across items of a test.

What does reliability reveal about a study?

Reliability and validity are concepts used to evaluate the quality of research. They indicate how well a method, technique or test measures something. Reliability is about the consistency of a measure, and validity is about the accuracy of a measure.

What would be the strongest evidence that a test is biased against some group?

Which of these would provide the strongest evidence that a test is biased against some group? The average score for this group is lower than that for some other group.

What must you do to improve the reliability of a measure?

Here are six practical tips to help increase the reliability of your assessment:

1. Use enough questions to assess competence.
2. Have a consistent environment for participants.
3. Ensure participants are familiar with the assessment user interface.
4. If using human raters, train them well.
5. Measure reliability.

How is reliability improved?

You can test reliability through repetition. The more similar repeated measurements are, the more reliable the results. The reliability of single measurements is not improved through repetition, but through the design of the experiment. Implementing a method that reduces random errors will improve reliability.

What is reliability of test?

Reliability refers to how dependably or consistently a test measures a characteristic. If a person takes the test again, will he or she get a similar test score, or a much different score? A test that yields similar scores for a person who repeats the test is said to measure a characteristic reliably.

What is an example of internal consistency reliability?

Internal consistency reliability is a way to gauge how well a test or survey is actually measuring what you want it to measure. Is your test measuring what it’s supposed to? A simple example: you want to find out how satisfied your customers are with the level of customer service they receive at your call center.

What is acceptable internal consistency?

Cronbach alpha values of 0.7 or higher indicate acceptable internal consistency…

What is a good internal consistency reliability score?

A negative number indicates that something is wrong with your data—perhaps you forgot to reverse score some items. The general rule of thumb is that a Cronbach’s alpha of . 70 and above is good, . 80 and above is better, and .

What does internal consistency tell us?

Internal consistency is an assessment of how reliably survey or test items that are designed to measure the same construct actually do so. A high degree of internal consistency indicates that items meant to assess the same construct yield similar scores. There are a variety of internal consistency measures.

What is the range of reliability?

The values for reliability coefficients range from 0 to 1.0. A coefficient of 0 means no reliability and 1.0 means perfect reliability. Since all tests have some error, reliability coefficients never reach 1.0.

Does Cronbach alpha measure reliability or validity?

Technically speaking, Cronbach’s alpha is not a statistical test – it is a coefficient of reliability (or consistency). As the average inter-item correlation increases, Cronbach’s alpha increases as well (holding the number of items constant).
