Regression Toward The Mean

A set of archival data was used to test the hypothesis that physical attractiveness is positively associated with socioeconomic status among men. Consistent with earlier research, more attractive men earned equivalent grades while undergraduates. They were also no more likely to have subsequently earned a graduate degree or to have held jobs characterized by higher status as indexed by Duncan (1961) prestige scores. Attractiveness itself was stable over the 25 yr. for those initially judged to be intermediate in attractiveness. Those who were initially most and least attractive were judged to have declined and increased, respectively, over the period in question, providing evidence for a regression toward the mean.

Regression Toward The Mean

There is another important artifactual contributor to the apparent improvement of persons subjected to an experimental intervention which may be mistaken for regression toward the mean. This is the phenomenon of random error and extreme selection, which does not at all involve the population regression of posttest on pretest scores but involves a quite different and independent reversion of subjects’ scores toward the population mean. These two independent threats to the internal validity of intervention evaluation studies, however, can be detected and differentiated on the sample data of such studies.

<b><i>Purpose:</i></b> The purpose of this study was to establish and characterize age- and gender-specific normative data of the singing voice using the voice range profile for clinical diagnostics. Furthermore, associations between the singing voice and the socioeconomic status were examined. <b><i>Methods:</i></b> Singing voice profiles of 1,578 mostly untrained children aged between 7.0 and 16.11 years were analyzed. Participants had to reproduce sung tones at defined pitches, resulting in maximum and minimum fundamental frequency and sound pressure level (SPL). In addition, maximum phonation time (MPT) was measured. Percentile curves of frequency, SPL and MPT were estimated. To examine the associations of socioeconomic status, multivariate analyses adjusted for age and sex were performed. <b><i>Results:</i></b> In boys, the mean of the highest frequency was 750.9 Hz and lowered to 397.1 Hz with increasing age. Similarly, the minimum frequency was 194.4 Hz and lowered to 91.9 Hz. In girls, the mean maximum frequency decreased from 754.9 to 725.3 Hz. The mean minimum frequency lowered from 202.4 to 175.0 Hz. For both sexes, the mean frequency range ∆f showed a constant range of roughly 24 semitones. The MPT increased with age, for boys and girls. There was neither an effect of age nor sex on SPL<sub>min</sub> or SPL<sub>max</sub>, ranging between 52.6 and 54.1 dBA and between 86.5 and 82.8 dBA, respectively. Socioeconomic status was not associated with the above-mentioned variables. <b><i>Conclusion:</i></b> To our knowledge, this study is the first to present large normative data on the singing voice in childhood and adolescence based on a high number of measurements. In addition, we provide percentile curves for practical application in clinic and vocal pedagogy which may be applied to distinguish between normal and pathological singing voice.

Covid-19 (Coronavirus Disease 2019) caused by Severe Acute Respiratory SyndromeCoronavirus 2 (SARS-CoV2) was declared a pandemic on March 11, 2020.Various stepshave been taken to control the spread of the Covid-19 pandemic that is currentlyhappening in Indonesia. Despite all the efforts of the government and media to educatethe public, the increase in the number of daily cases in Indonesia has not shown adecline. This encourages researchers to assess the level of public knowledge andperceptions because factors have an influence on individual health behavior that cancontribute to pandemic control efforts. This research uses study method observationaldescriptive. The population in this study were 343 people who filled out a researchquestionnaire conducted by the IKM-IKK FK Unsri department. For 251 respondents whofilled out the online questionnaire completely, the mean age was 23.78 ± 7.46, 63.7%female, 63.7% college graduates, 77.7% Muslim, and the majority of occupations arecollege students and students (54.6%). In the assessment of knowledge, 137 people(35.7%) had a good level of knowledge with a mean valueknowledge 13.25 ± 3.2. Themajority of respondents have a good perception, namely 249 people (99.2%) with morethan half showing a positive perception of the risk of infection if not taking precautions,the importance of wearing masks and physical distancing, hand washing behavior, self-isolation, and consumption of nutritious food during the Covid-19 pandemic..

Two Age Groups

In Exp. 2 of Siegler's 1976 study a faulty quasi-experimental design was used. The stated results, that older and younger children with apparently equal initial performance derived different benefits from identical experience, can also be explained by a confounding with regression toward the mean. These effects are a result of a selective matching of subjects from two age groups on a fallible variable correlated with age.
