Surveys

17.1K
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Systematic Error: Methodological and Sampling Errors

11.1K
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...

Convenience Sampling Method00:55

Convenience Sampling Method

11.8K
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.
Convenience sampling is a non-random method of sample selection; this method selects individuals that are easily accessible and may result in biased data. For example, a marketing...

Bias01:22

Bias

7.4K
Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...

Random Sampling Method

15.1K
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. Among the various sampling methods used by...

Group Design02:01

Group Design

10.9K
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...

科学分野:

  • 調査方法論; 統計的推論; 健康研究

背景:

  • 非確率標本は健康研究でますます使用されています。これらの標本における参加メカニズムは不明であることが多く、推定値や関連性におけるバイアスの原因となります。非確率標本からの統計的推論のための既存の方法は、単一の参照サンプルに限定されています。

研究 の 目的:

  • 複数の参照調査を用いた非確率標本における参加バイアスに対処するための一般的なフレームワークを提案すること。単一参照サンプル制限を超えた統計的推論能力を拡張すること。実用的な実装と柔軟性のためのキャリブレーション推定量に焦点を当てること。

主な方法:

  • 複数の参照調査に対応する一般的なフレームワークを開発しました。フレームワーク内の柔軟な特殊ケースであるキャリブレーション推定量に焦点を当てました。テイラー線形化と leave-one-out ジャックナイフの2つの分散推定方法を提案しました。

主要な成果:

  • 提案されたフレームワークは、参加バイアスを効果的に対処しました。レーキング比キャリブレーション推定量は、特に分散した参加確率において満足のいくパフォーマンスを示しました。提案された方法を使用した連続アウトカムの分散推定値は、著しく小さくなりました。

結論:

  • 新しいフレームワークとキャリブレーション推定量は、非確率標本におけるバイアスを効果的に軽減します。これらの方法は、特に限られたミクロデータアクセスにおいて実用的な利点を提供します。カナダの働く成人に関する実世界の研究で有用性が実証されました。
