According to Lather (1991) he identified four types of validation (triangulation, construct validation, face validation, and catalytic validation) as a reconceptualization of validation.. True or False: A thermometer that gives faulty readings over and over would be considered a systematic error. The passage of time in an experiment interferes with the Validity of the measurement. By checking the consistency of results across time, across different observers, and across parts of the test itself. In this, the results are considered not to be reliable, giving inconsistent consistent results, but they are considered to be valid, meaning that something accurately measures something else. They indicate how well a method, technique, or test measures something. High speed cinematography, motion capture, film footage To operationalize these terms, long engagement in the field and the triangulation of data sources, methods, and investigators to establish credibility. In recent years, the field of psychology has been confronting serious questions about whether some of its research practices (e.g., "p-hacking", undervaluing replication, failing to publish null results) undermine the validity of its findings. The scale was Valid once for reading a correct weight; however, because the result was not consistent it is not a reliable measurement. control pieces and how its influenced, Locomotion - how you get from one place to another; walking, running, hopping, skipping, Reliability shows how trustworthy is the score of the test. Have all your study materials in one place. This is especially important if multiple researchers are involved. Reliability refers to a study's replicability, while validity refers to a study's accuracy. Fiona Middleton. A reliable test means that it should give the same results for similar groups of students and with different people marking. They also assure readers that the findings of the study are credible and trustworthy. This consistency and dependability add value to the tests being used in research. OBJECTIVITY IN RESEARCH . Internal validityis the ability to draw a causal link between your treatment and the dependent variable of interest. The tests could be written and oral tests on the same topic. This is the moment to talk about how reliable and valid your results actually were. How do we assess reliability and validity?

Validity shows how a specific test is suitable for a particular situation. Usability. You step on a new weight scale and see an accurate number on the scale of how much you weigh. By using multiple forms of similar tests, a researcher can indicate whether the measurement is reliable depending on the consistency of an outcome. - speed = 1 / (time/unit) Consider a test that aims to measure reading comprehension.

How might a participant or test be affected during this time allotted? amount of error we have in terms of measurement; highly sensitive = accurate in error reporting,; For example, in an experimental setup, make sure all participants are given the same information and tested under the same conditions. Regarded frequently in early research, Absolute constant error (ACE) -> in a group setting, how far group is from target on average, New skills will have more error, as they familiarize the errors get less, Constant error: stabilizes after a few trials (closer to the target) less sensitive = less able to describe the quality of the error and all we look at is existence of When scientific results are frequently cited in textbooks and TED Talks, the stakes for validity are high. Andrew Johnson is a contributing fellow with the USC Center for Religion and Civic Culture. 4. Questions asked about method error include: Is the experimenter using the tool of measurement correctly?
