Uncertainty in Measurement: Accuracy and Precision03:37

Uncertainty in Measurement: Accuracy and Precision

73.5K
Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value.

Reliability and Validity01:29

Reliability and Validity

12.7K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Accuracy and Errors in Hypothesis Testing01:13

Accuracy and Errors in Hypothesis Testing

180
Hypothesis testing is a fundamental statistical tool that begins with the assumption that the null hypothesis H0 is true. During this process, two types of errors can occur: Type I and Type II. A Type I error refers to the incorrect rejection of a true null hypothesis, while a Type II error involves the failure to reject a false null hypothesis.
In hypothesis testing, the probability of making a Type I error, denoted as α, is commonly set at 0.05. This significance level indicates a 5%...

Random and Systematic Errors01:20

Random and Systematic Errors

10.9K
Scientists always try their best to record measurements with the utmost accuracy and precision. However, sometimes errors do occur. These errors can be random or systematic. Random errors are observed due to the inconsistency or fluctuation in the measurement process, or variations in the quantity itself that is being measured. Such errors fluctuate from being greater than or less than the true value in repeated measurements. Consider a scientist measuring the length of an earthworm using a...

Propagation of Uncertainty from Systematic Error

The atomic mass of an element varies due to the relative ratio of its isotopes. A sample's relative proportion of oxygen isotopes influences its average atomic mass. For instance, if we were to measure the atomic mass of oxygen from a sample, the mass would be a weighted average of the isotopic masses of oxygen in that sample. Since a single sample is not likely to perfectly reflect the true atomic mass of oxygen for all the molecules of oxygen on Earth, the mass we obtain from this...

Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...

Summary
This summary is machine-generated.

Training to detect complications in truthful accounts did not improve accuracy in veracity judgments. Observers did not accurately detect complications, even when trained, suggesting limitations in current training methods for lie detection.

Area of Science:

  • Psychology
  • Forensic Psychology
  • Cognitive Psychology

Background:

  • Complications are more frequent in truthful accounts compared to deceptive ones.
  • Previous research has not experimentally assessed the impact of complication detection training on veracity judgments.

Purpose of the Study:

  • To investigate the accuracy of observers' veracity judgments when focusing on complications in transcripts.
  • To determine if training to detect complications enhances the accuracy of distinguishing truthful from deceptive accounts.

Main Methods:

  • 87 participants judged 10 transcripts (5 truthful, 5 false).
  • Participants were divided into trained (n≈44) and untrained (n≈43) groups.
  • The trained group received instruction on detecting complications.

Main Results:

  • Trained participants actively searched for complications more than untrained participants.
  • Despite searching, trained participants did not accurately detect complications.
  • Veracity judgment accuracy did not differ significantly between trained and untrained groups.

Conclusions:

  • Training to detect complications did not improve the accuracy of veracity judgments.
  • The brief or insensitive nature of the training may explain the lack of improvement.
  • Further research is needed to develop more effective training protocols for lie detection based on complications.
