Distance Corrections01:15

Distance Corrections

278
To achieve precise distance measurements, especially in surveying and construction, certain corrections must be applied to account for potential sources of error like the standardization errors, temperature variations, and slope adjustments.Standardization error emerges when measurement equipment undergoes changes, such as wear, repairs, or weather impacts. To address this, surveyors compare the equipment’s readings to a standard. This process identifies any deviation that might lead to...

Adjusting a Traverse01:12

Adjusting a Traverse

372
In the site survey of a four-sided traverse, internal angles are essential to ensure geometric accuracy. The survey revealed that the sum of the measured internal angles was 359 degrees and 48 minutes, which is 12 minutes less than the expected 360 degrees. This discrepancy signals an error likely arising from measurement inaccuracies during the fieldwork.To rectify this error, the adjustment process involved distributing the 12-minute shortfall equally across the four internal angles. By...

The Anchoring-and-Adjustment Heuristic

7.7K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

Detection of Gross Error: The Q Test

6.9K
When one or more data points appear far from the rest of the data, there is a need to determine whether they are outliers and whether they should be eliminated from the data set to ensure an accurate representation of the measured value. In many cases, outliers arise from gross errors (or human errors) and do not accurately reflect the underlying phenomenon. In some cases, however, these apparent outliers reflect true phenomenological differences. In these cases, we can use statistical methods...

Margin of Error01:27

Margin of Error

7.0K
The margin of error is also called the maximum error of an estimate. The margin of error is the maximum possible or expected difference between the observed sample parameter value and the actual population parameter value. For proportion, it is the maximum difference between the value of sample proportion obtained from the data and the true value of population proportion. As the true value of the population parameter is not known, the margin of error is calculated using the sample statistic.

Accuracy and Errors in Hypothesis Testing01:13

Accuracy and Errors in Hypothesis Testing

562
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%...

Area of Science:

  • Cognitive Neuroscience
  • Neuroscience
  • Psychology

Background:

  • The brain exhibits post-error adaptations to enhance future performance.
  • Observed adaptations include behavioral changes like post-error slowing (PES), reduced interference, and improved accuracy (PIA).
  • Neuronal adaptations involve changes in task-relevant and distracter-encoding brain areas, motor system modulations, and increased mid-frontal theta power.

Purpose of the Study:

  • To review current literature on post-error adjustments (behavioral and neuronal).
  • To discuss conditions influencing these adaptations and their interrelationships.
  • To evaluate functional explanations for PES and present new data.

Main Methods:

  • Literature review of functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) studies.
  • Reanalysis of data from flanker and moving dots interference tasks.
  • Investigation of post-error slowing (PES) reliability and influencing factors.

Main Results:

  • Post-error slowing (PES) and post-error improvement in accuracy (PIA) are not always correlated.
  • PES is dependent on the response-stimulus interval.
  • PES demonstrates within-subject reliability over extended periods.

Conclusions:

  • Post-error adaptations are multifaceted, encompassing behavioral and neuronal changes.
  • The relationship between different adaptation types requires further investigation.
  • Post-error slowing (PES) is a reliable phenomenon influenced by temporal factors, suggesting its functional significance in cognitive control.
