Surveys

14.7K
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Atomic Absorption Spectroscopy: Overview01:27

Atomic Absorption Spectroscopy: Overview

1.5K
Atomic absorption spectroscopy (AAS) is a technique used to analyze elements by measuring electromagnetic radiation (EMR) absorbed by atoms, which causes them to transition to a higher-energy orbit. The most crucial step in AAS is atomization, where the analyte is converted into gas-phase atoms, typically through a flame or furnace. Some of these atoms become thermally excited in the flame, while most remain in the ground state.
When irradiated by EMR of a particular wavelength, these...

Statistical Analysis System (SAS)01:14

Statistical Analysis System (SAS)

128
SAS, short for Statistical Analysis System, is a powerful data analysis, management, and visualization tool. Developed by the SAS Institute in the early 1970s, SAS has evolved into a comprehensive software suite used across various industries for statistical analysis, business intelligence, and predictive modeling.
Applications: SAS finds applications in numerous fields, including healthcare for clinical trial analysis, finance for risk assessment, marketing for customer data analysis, and...

Intelligence01:27

Intelligence

6.8K
The term "intelligence" is complex because it refers to both behavior and individuals, and its interpretation varies across cultures. European Americans tend to link intelligence with reasoning and cognitive skills, while in Kenya, it is tied to responsible participation in family and social life. In Uganda, intelligence is seen as the ability to know the right actions and carry them out effectively, while the Iatmul people of Papua New Guinea associate it with the capacity to remember...

What is an ANOVA?01:16

What is an ANOVA?

7.8K
The Analysis of Variance or ANOVA is a statistical test developed by Ronald Fisher in 1918. It is performed on three or more samples to check for equality between their means.
Before performing ANOVA, one must ensure that the samples used for this analysis have three crucial characteristics or statistical assumptions. The first assumption states that the samples should be drawn from normally distributed samples, while the second requires that all the drawn samples should be randomly and...

Area of Science:

  • Social and health sciences research infrastructure.
  • Longitudinal studies on life course disparities.

Background:

  • The Understanding America Study (UAS) is a probability-based internet panel at USC.
  • It collects diverse data including surveys, DNA, wearables, and administrative linkages.

Purpose of the Study:

  • To identify factors contributing to racial, ethnic, geographic, and socioeconomic disparities over the life course.
  • To optimize engagement with the research community for data dissemination and input.

Main Methods:

  • Recruitment of ~15,000 US residents via Address-Based Sampling.
  • Provision of internet-enabled tablets and surveys in English and Spanish.

Main Results:

  • Over 600 surveys conducted since 2014, including health, cognitive, and personality assessments.
  • Numerous publications on topics like COVID-19 mental health effects, physical activity measurement bias, and decision-making in older adults.

Conclusions:

  • The UAS infrastructure supports extensive research on social and health inequalities.
  • Future plans include sample growth and integration of more non-interview data.
