How Data are Classified: Numerical Data

37.1K
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

43.1K
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...

Area of Science:

  • Oncology and Public Health Informatics
  • Geographic Information Systems (GIS) in Health
  • Data Visualization and Epidemiology

Background:

  • Effective cancer research requires accessible, shareable, and visually interpretable data.
  • Existing platforms may lack integrated global cancer statistics and user-friendly visualization tools.
  • The need for a centralized resource to explore cancer trends across different regions and demographics is critical.

Purpose of the Study:

  • To develop a dynamic, collaborative online map for global cancer data exploration and sharing.
  • To integrate diverse cancer-related datasets (mortality, incidence, prevalence, survival, demographics) into a unified platform.
  • To enhance cancer research by providing researchers with tools to visualize and disseminate critical epidemiological information.

Main Methods:

  • Development of a database-driven, 2-scale (global and country-level) map using Google Maps API and AJAX.
  • Integration of data from reputable sources: IARC, IHME, World Bank, and Taiwan's Department of Health.
  • Implementation of seven distinct visualization techniques (choropleth, tornado, treemap, sunburst, line, bar, heatmap) for data presentation.

Main Results:

  • A functional world cancer map (http://worldmap.csmu-liawyp.tw) presenting cancer data from 150 countries.
  • Visualization of cancer prevalence, mortality rates (crude and age-standardized), incidence, survival, and trends.
  • Demonstration of variations in cancer data across countries and demographic groups.

Conclusions:

  • The developed online map serves as a valuable, easily maintainable platform for researchers to manage and disseminate cancer data.
  • The integrated visualization tools facilitate a deeper understanding of global cancer patterns and facilitate collaborative research.
  • This resource empowers researchers with accessible, visualized cancer statistics, supporting public health initiatives and epidemiological studies.
