In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

Random and Systematic Errors

14.8K
Scientists always try their best to record measurements with the utmost accuracy and precision. However, sometimes errors do occur. These errors can be random or systematic. Random errors are observed due to the inconsistency or fluctuation in the measurement process, or variations in the quantity itself that is being measured. Such errors fluctuate from being greater than or less than the true value in repeated measurements. Consider a scientist measuring the length of an earthworm using a...

Systematic Sampling Method

13.0K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
Systematic sampling is one of the simplest methods...

Propagation of Uncertainty from Systematic Error

The atomic mass of an element varies due to the relative ratio of its isotopes. A sample's relative proportion of oxygen isotopes influences its average atomic mass. For instance, if we were to measure the atomic mass of oxygen from a sample, the mass would be a weighted average of the isotopic masses of oxygen in that sample. Since a single sample is not likely to perfectly reflect the true atomic mass of oxygen for all the molecules of oxygen on Earth, the mass we obtain from this...

In the case of systematic errors, the sources can be identified, and the errors can be subsequently minimized by addressing these sources. According to the source, systematic errors can be divided into sampling, instrumental, methodological, and personal errors.
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...

Summary

Self-harm in older adults presents unique characteristics, including self-poisoning and comorbid physical issues. Identifying these patterns is crucial for preventing suicide, which has a higher risk in this demographic.

Area of Science:

  • Gerontology
  • Public Health
  • Psychiatry

Background:

  • Self-harm is a significant public health issue, particularly in aging populations.
  • Older adults face a high risk of suicide, necessitating identification of specific self-harm characteristics.

Purpose of the Study:

  • To systematically review the distinct characteristics of self-harm among older adults.

Main Methods:

  • A comprehensive literature search was conducted across multiple electronic databases up to February 2018.
  • Articles were screened, assessed for quality, and data were synthesized narratively.
  • A patient advisory group contributed to the study's design and interpretation.

Main Results:

  • The review included 40 articles, encompassing data from 62,755 older adults.
  • Self-poisoning was the most frequent method; comorbid physical problems were common.
  • Motivations included loss of control, loneliness, and perceived burdensome aging; higher repetition risk was noted with prior psychiatric treatment.

Conclusions:

  • Self-harm in older adults exhibits unique features requiring tailored management and care strategies.
  • The elevated suicide risk in older adults underscores the importance of early detection and prevention.
  • Further community-based research is needed to complement existing hospital-based findings.
