Data Collection II01:29

Data Collection II

10.1K
The nursing history captures and records the patient's health status, so that a care plan evolves to meet the patient's individual needs. The nursing health history is a part of the initial assessment. A comprehensive history covers all health dimensions and plays a significant role in the assessment process. A comprehensive history includes the patient's biographical information, reasons for seeking health care, expectations, present and past health history, medications, and...

Data Collection I

Data collection gathers information needed to make accurate judgments about a patient's present condition. During a health history interview, subjective data is collected from the patient, their caregivers, or family members, and objective data is collected through observations and physical assessment. Patients are the primary source of subjective data. Thus information gathered from patients through interviews, observations, and physical examination is primary data. Secondary sources of...

Data collection is a systematic method of obtaining, observing, measuring, and analyzing accurate information. An experimental study is a standard method of data collection that involves the manipulation of the samples by applying some form of treatment prior to data collection. It refers to manipulating one variable to determine its changes on another variable. The sample subjected to treatment is known as “experimental units.”
An example of the experimental method is a public...

Data Collection by Survey

9.1K
The systematic method of obtaining and analyzing accurate information of a population is called data collection. A survey is a standard method of data collection that involves collecting information from a target human population about their experience, opinion, or knowledge of a product, service, or process. The responses are recorded and interpreted. The most common survey examples are written questionnaires, face-to-face or telephonic conversations, focus groups, and electronic (e-mail or...

Data collection refers to a systematic way of obtaining, observing, measuring, and analyzing accurate information. Observational studies are one of the most widely used methods of data collection. It involves collecting data by observing the behavior and physical characteristics of a sample without making any modifications to the sample.
An astronomer viewing the motion and brightness of stars in the sky and recording the data is an example of observational data collection. A botanist recording...

Data Collection III

The physical assessment examines the patient for objective data that defines the patient's condition, and aids in formulating the nursing care plan. The purpose of physical assessment is a health status appraisal, which includes identifying health problems, and establishing a database for nursing intervention.
The principles to begin the physical assessment include conducting a comprehensive or problem-related history in a quiet, well-lit room, emphasizing privacy and comfort for the...

Area of Science:

  • Cognitive Psychology
  • Human-Computer Interaction
  • Decision Science

Background:

  • Dynamic decision-making tasks require understanding information search processes.
  • Existing methods may not adequately capture the sequential nature of information acquisition.
  • Researchers need tools to study how individuals process complex, dynamic information.

Purpose of the Study:

  • To describe DynaSearch, a novel web-based system for conducting process-tracing experiments.
  • To provide a tool for examining information search strategies in dynamic decision-making.
  • To facilitate the collection and analysis of detailed decision-making process data.

Main Methods:

  • DynaSearch supports the creation and administration of web-based experiments.
  • It incorporates between- and within-subjects experimental factors.
  • Information acquisition (verbal, numeric, graphic) and decision data are recorded.
  • Questionnaires assess information recall, inference, and response decisions.

Main Results:

  • The system records detailed participant interactions with information.
  • It allows for the verification of task completion via an online viewer.
  • Data can be downloaded in a format compatible with statistical analysis packages.

Conclusions:

  • DynaSearch offers a comprehensive solution for studying dynamic decision-making processes.
  • It enables researchers to investigate information search behaviors in detail.
  • The system facilitates the quantitative analysis of decision-making under dynamic conditions.
