(July 2023) (Learn how and when to remove this message) A hospital receiving more vaccinated COVID-19 patients than unvaccinated ones might suggest that the vaccine is ineffective, but such an imbalance is to be expected within a highly vaccinated population.[1] The base rate fallacy,
In applied statistics, (e.g., applied to the social sciences and psychometrics), common-method variance (CMV) is the spurious "variance that is attributable to the measurement method rather than to the constructs the measures are assumed to represent"[1] or equivalently as "systematic error variance shared among variables measured with and introduced as a function of the same method and/or source"
The Concept of Model: Definitions and Types (If you wonder at some wording, please consult the tentative translation key) Difficulties with the definition of model Each definition of „model” is insufficient: It covers only a small range of the reach of use. In particular all definitions with the terms „original”, „reality” and „representation” cannot convince. The German “Brockhaus” (1971) offers

Translating IPIP Items into Other Languages This web-site serves as a clearing-house for those who plan to translate the English IPIP items into other languages. If you have already translated any IPIP items, or plan to do so, please contact Lewis R. Goldberg at: lewg@ori.org Beginning in January 2016, links are being added to translated item sets as they become available. The accuracy of the prov
Take one of our free personality tests, many of which are based on peer-reviewed scientific research, and all of which are crafted by experts in psychometrics. Gay Type Test Based on the work of sociologist Richard Hauser’s 1962 study, the Gay Type test will determine what kind of pre-liberation male homosexual you would be.
Psychologist Michal Kosinski’s work shows how digital footprints can predict a person’s sexual orientation, political views and more. Is it a danger or a warning about threats to privacy? John Morgan reports from California Michal Kosinski has only just published his latest paper, but, later in the same day, the Stanford University psychologist and data scientist is already seeing criticism emerge
I started writing on LinkedIn in April, and I've produced an article approximately once every two weeks or so. It's been enjoyable (and maybe even a little cathartic) to get ideas down in written form, and I have found it a helpful way to organize my thoughts in an exciting, rapidly growing field where a lot is happening currently. I thought it might be useful to organize my output from 2017 in a
John, 12-years-old, is three times as old as his brother. How old will John be when he is twice as old as his brother? Two families go bowling. While they are bowling, they order a pizza for £12, six sodas for £1.25 each, and two large buckets of popcorn for £10.86 [each]. If they are going to split the bill between the families, how much does each family owe? 4, 9, 16, 25, 36, ?, 64. What number
In statistical models applied to psychometrics, congeneric reliability ("rho C")[1] a single-administration test score reliability (i.e., the reliability of persons over items holding occasion fixed) coefficient, commonly referred to as composite reliability, construct reliability, and coefficient omega. is a structural equation model (SEM)-based reliability coefficients and is obtained from on a
Construct validity concerns how well a set of indicators represent or reflect a concept that is not directly measurable.[1][2][3] Construct validation is the accumulation of evidence to support the interpretation of what a measure reflects.[1][4][5][6] Modern validity theory defines construct validity as the overarching concern of validity research, subsuming all other types of validity evidence[7
社会科学者は社会科学に固有のものではありません。ほとんどが統計的方法の広い範囲を使用します。実際に、社会科学の中で最も統計的データ解析は、標準のRの配布の一部である基本機能と推奨パッケージでカバーされています。以下のパッケージの説明では、私は最初の言及で基本および推奨パッケージを特定します。特に「推奨」または「R-base」として識別されていないパッケージは、貢献パッケージです。 その他の関連タスクビュー： 基本と貢献パッケージ以外に、一般的に社会科学で用いられる方法の多くは、次のような他のCRANタスクビューに広くカバーされています。他のタスクのビューに存在する重複情報を最小化して、アルファベット順で表示します。 Bayesian：混合効果モデルを含む社会科学者への関心のさまざまな設定でのベイズ推定の方法。 EconometricsとFinance：エコノミストや金融アナリストに固有の関
