How Data are Classified: Categorical Data01:11

How Data are Classified: Categorical Data

45.0K
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...

How Data are Classified: Numerical Data

38.1K
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...

Data Reporting and Recording

5.5K
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...

Gene Flow02:39

Gene Flow

38.0K
Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.

Gene Families01:57

Gene Families

10.0K
Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.
Occasionally these regions can be adapted to take on new roles within the organism, becoming novel genes...

Gene Therapy00:59

Gene Therapy

27.7K
Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Summary
This summary is machine-generated.

The heritability of human longevity is likely lower than previously thought, estimated between 0.10 and 0.15. This finding complicates the search for longevity genes but still offers potential genetic insights.

Area of Science:

  • Genetics
  • Gerontology
  • Human Pedigree Analysis

Background:

  • Understanding the genetic basis of human longevity is crucial for public health.
  • Previous estimates suggested a higher heritability for longevity.
  • Large-scale human pedigree data is essential for accurate genetic analyses.

Purpose of the Study:

  • To re-evaluate the heritability of human longevity using extensive genealogical data.
  • To identify potential genetic factors influencing lifespan.
  • To assess the feasibility of finding specific longevity genes.

Main Methods:

  • Analysis of a large human pedigree derived from public genealogy databases.
  • Quantitative genetic methods to estimate heritability.
  • Statistical analysis to identify significant genetic influences on longevity.

Main Results:

  • Heritability of longevity estimated to be between 0.10 and 0.15.
  • This estimate is significantly lower than previous figures (0.25 to 0.30).
  • Despite lower heritability, some significant genetic results were identified.

Conclusions:

  • The genetic contribution to human longevity may be smaller than previously assumed.
  • The search for specific longevity genes presents a greater challenge.
  • Further research and validation are needed to confirm and extend these findings for potential insights into aging and lifespan.
