How Data are Classified: Numerical Data00:59

How Data are Classified: Numerical Data

37.0K
Data that are countable or measurable in specific units are called numerical or quantitative data. Quantitative data are always numbers. Quantitative data are the result of counting or measuring the attributes of a population. Amount of money, pulse rate, weight, number of people living in a town, and number of students who opt for statistics are examples of quantitative data.
Quantitative data may be either discrete or continuous. All quantitative data that take on only specific numerical...

How Data are Classified: Categorical Data

43.0K
A variable, usually notated by capital letters such as X and Y, is a characteristic or measurement that can be determined for each member of a population. Data are the actual values of variables. They may be numbers, or they may be words. Datum is a single value.
Data are classified based on whether they are measurable or not. Categorical data cannot be measured; instead, it can be divided into categories. For example, if Y denotes a person's party affiliation, some examples of Y include...

Data Reporting and Recording

5.4K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

Data Collection I01:30

Data Collection I

7.9K
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 Validation01:03

Data Validation

6.4K
Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.
Nursing assessment guides are generally based on holistic models rather than medical...

Method validation is a crucial process in analytical chemistry designed to confirm that a given method consistently produces reliable and high-quality results. This process is essential when a method is applied to different sample matrices or when procedural modifications are made, ensuring that the results meet acceptable standards across various applications.
Key parameters for method validation include:

Area of Science:

  • Automotive telematics
  • Insurance risk assessment
  • Behavioral analysis in driving

Background:

  • Usage-based insurance (UBI) schemes offer advanced risk management for insurers.
  • Understanding driver behavior's impact on crash risk is crucial for UBI product development.
  • Current UBI models require deeper insights into behavioral factors influencing insurance claims.

Purpose of the Study:

  • To analyze automotive telematics data to identify key driver behaviors associated with crash risk.
  • To develop and apply an innovative methodology for selecting control (crash-free) drivers.
  • To quantify the relationship between specific driving behaviors and the likelihood of a crash.

Main Methods:

  • Analysis of a large dataset comprising over 28 million automotive telematics trips.
  • Implementation of a case-control study methodology comparing crash-involved drivers with crash-free drivers.
  • Application of logistic regression modeling to identify significant predictors of crash risk.

Main Results:

  • Speeding emerged as the most influential driver behavior correlating with increased crash risk.
  • The study identified specific behavioral patterns differentiating high-risk drivers from low-risk drivers.
  • The innovative control driver selection method proved effective in isolating behavioral influences.

Conclusions:

  • Speeding is a primary behavioral determinant of crash risk within usage-based insurance contexts.
  • Telematics data and advanced statistical modeling can significantly enhance the accuracy of UBI risk assessment.
  • Findings support the potential for UBI to promote safer driving habits and reduce insurance claims.
