What is a Mode?01:07

What is a Mode?

25.2K
The mode is one of the commonly used measures of a central tendency. It is defined as the most frequent value in a data set.
There can be more than one mode in a data set if multiple values have the same highest frequency. For instance, suppose that the Statistics exam scores of 20 students are: 50; 53; 59; 59; 63; 63; 72; 72; 72; 72; 72; 76; 78; 81; 83; 84; 84; 84; 90; 93. Here, the mode is 72, as it occurs most frequently, five times.
A data set with two modes is called bimodal. For example,...

Ventilatory Modes01:14

Ventilatory Modes

1.5K
Mechanical ventilators are life-saving devices that support or replace spontaneous breathing. They deliver breaths to patients through varying methods known as ventilator modes. Understanding these modes is critical for healthcare providers managing patients with respiratory failure.
There are three ventilatory modes: full support, partial support, and spontaneous. These are described below.
Full Support Modes
Full support modes include controlled mechanical ventilation, continuous mandatory...

Location and Orientation of the Heart01:13

Location and Orientation of the Heart

9.7K
The human heart, despite its modest size and weight, is an organ of remarkable strength and endurance. Roughly the size of a fist, the heart weighs between 250 and 350 grams and is nestled within the mediastinum, the medial cavity of the thorax. It extends obliquely for about 12 to 14 cm, resting on the superior surface of the diaphragm. The heart is positioned anterior to the vertebral column and posterior to the sternum, with two-thirds of its mass lying to the left of the midsternal line.

Frustration and Conflict: Approach-Approach, Approach-Avoidance01:20

Frustration and Conflict: Approach-Approach, Approach-Avoidance

505
Frustration occurs when people are obstructed or prevented from achieving a desired goal or fulfilling a perceived need. For example, when someone's input is ignored in a discussion, it can lead to feelings of frustration. Conflict, however, arises from opposing interests, goals, or actions. Conflicts can take various forms based on the nature of these opposing desires or goals.
One common type of conflict is the Approach–Approach Conflict. In this case, a person faces two desirable...

Selected Data About Geographic Locations01:25

Selected Data About Geographic Locations

265
Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...

Perceiving Loudness, Pitch, and Location01:21

Perceiving Loudness, Pitch, and Location

965
The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...

Area of Science:

  • Transportation Safety
  • Public Health
  • Human-Computer Interaction

Background:

  • Traditional transportation safety assessments rely heavily on crash data, which may not fully capture public perceptions of safety, especially for vulnerable road users.
  • Existing research on pedestrian and cyclist conflicts often focuses narrowly on intersections, limiting a comprehensive understanding of non-crash safety events.
  • Perceptions of safety significantly influence the adoption of active transportation, highlighting the need for broader safety assessment measures.

Purpose of the Study:

  • To develop an innovative and cost-effective method for collecting conflict data involving vulnerable road users (VRUs) and assessing its severity.
  • To evaluate the effectiveness and practicality of a crowd-sourced data collection approach using a mobile application.
  • To provide communities and agencies with a low-cost data source for informing safety-related decisions and infrastructure planning.

Main Methods:

  • Development of an Android-based application for crowd-sourced collection of road user conflict data.
  • Comparison of crowd-sourced conflict data with traditional fatality data for hot spot analysis.
  • Collection of user feedback on the application's interface and features.

Main Results:

  • The study successfully developed and tested a crowd-sourced data collection app for identifying road user conflicts.
  • Crowd-sourced data provides a complementary dataset to traditional fatality data for safety analysis.
  • User feedback indicated the app's potential for community-led safety identification.

Conclusions:

  • The developed crowd-sourced app offers a practical and cost-effective solution for collecting valuable transportation safety data, particularly concerning vulnerable road users.
  • Widespread adoption of the app can empower communities to identify and address safety concerns, thereby informing policy and infrastructure improvements.
  • This approach enhances traditional safety metrics by incorporating conflict data and user perceptions, leading to more informed decision-making.
