When a historian uses the skill of corroboration?

Explanation: Corroboration is the action of double checking information from one source, and searching for different sources, this is done in several social sciences, like history, sociology, anthroplogy, and in journalism, to chech te veracity of information that we have from a source.

What does corroborating sources allow a historian to do?

Answer: C, determine whether an assertion made by one source is likely to be true.

Why is it important for historians to corroborate information when trying to determine what happened in the past?

Historians corroborate evidence when they try to figure out what happened in the past. If they find multiple pieces of evidence that support their initial hunch, their case becomes stronger. Because the goal of corroboration is to build a strong argument, it also involves sourcing.

Is reliability necessary for validity?

Test score reliability is a component of validity. If test scores are not reliable, they cannot be valid since they will not provide a good estimate of the ability or trait that the test intends to measure. Reliability is therefore a necessary but not sufficient condition for validity.

Why the test must be reliability?

Reliability refers to the degree to which scores from a particular test are consistent from one use of the test to the next. Of great importance is that the test items or rubrics match the learning outcomes that the test is measuring and that the instruction given matches the outcomes and what is assessed.

How do you know if assessments are valid and reliable?

For a test to be reliable, it also needs to be valid. For example, if your scale is off by 5 lbs, it reads your weight every day with an excess of 5lbs. The scale is reliable because it consistently reports the same weight every day, but it is not valid because it adds 5lbs to your true weight.

What is reliability and example?

The term reliability in psychological research refers to the consistency of a research study or measuring test. For example, if a person weighs themselves during the course of a day they would expect to see a similar reading. If a test is reliable it should show a high positive correlation.

What is a good reliability score?

Table 1. General Guidelines for

Reliability coefficient value Interpretation
.90 and up excellent
.80 – .89 good
.70 – .79 adequate
below .70 may have limited applicability

What does it mean if a test is reliable and valid?

Test reliablility refers to the degree to which a test is consistent and stable in measuring what it is intended to measure. Most simply put, a test is reliable if it is consistent within itself and across time. Test validity refers to the degree to which the test actually measures what it claims to measure.

What are some problems with intelligence tests?

IQ tests have the potential to inaccurately measure an individual’s intelligence and cause problems including low confidence, unrealistic expectations, and just a generally flawed understanding of a person’s potential.

What makes a experiment valid?

To gain meaningful results, experiments are well designed and constructed to minimize the effects of elements other than the treatment. Four basic components that affect the validity of an experiment are the control, independent and dependent variables, and constants.

Does online testing lack validity?

Relationship Of Reliability To Validity. A reliable test is not necessarily a valid test. A test can be internally consistent (reliable) but not be an accurate measure of what you claim to be measuring (validity).

How do I make my online test valid?

Tips for Creating Valid Tests

  1. Make sure your test matches your learning objective.
  2. Match the difficulty of the test with the difficulty of the real-world task.
  3. Ask real-world experts (so-called subject matter experts) for their input in creating the test to match real-world expectations and experiences.

How do you test content validity?

Content validity is primarily an issue for educational tests, certain industrial tests, and other tests of content knowledge like the Psychology Licensing Exam. Expert judgement (not statistics) is the primary method used to determine whether a test has content validity.
