认知测试得分因人口而异. 本研究介绍了方法和一个R包, test2norm,以纠正年龄,教育和性别的得分,改善中枢神经系统 (CNS) 功能障碍的检测.
科学领域:
- 神经科学是一个神经科学.
- 心理测量 心理测量 心理测量
- 生物统计学 生物统计学
背景情况:
- 认知测试的表现自然会因年龄,教育和性别等人口因素而有所不同.
- 这些变异可以掩盖或模仿由中枢神经系统 (CNS) 功能障碍引起的认知缺陷.
- 准确的评估需要考虑预期的人口影响.
研究的目的:
- 详细说明为认知测试生成基于回归的规范标准的过程.
- 为将这些标准应用于有中枢神经系统功能障碍风险的个人和人群提供指导方针.
- 引入R包"test2norm"用于创建和应用规范公式.
主要方法:
- 描述了使用大型,多样化的控制队伍开发基于回归的规范标准的方法.
- 概述了这些规范标准的实际应用的建议.
- 开发和记录了"test2norm" R包,用于自动化评分校正.
主要成果:
- 建立了一个强大的框架来生成人口统计学纠正的认知分数.
- 证明了规范性标准在识别偏离预期性能方面的有用性.
- 为实现这些纠正提供了一个用户友好的R包.
结论:
- 基于回归的规范性校正对于在人口变化的情况下进行准确的认知评估至关重要.
- "test2norm"套件有助于应用这些纠正,有助于检测中枢神经系统相关的认知障碍.

Testing a Claim about Population Proportion
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...
Testing a Claim about Mean: Known Population SD
Estimating a population mean requires the samples to be distributed normally. The data should be collected from the randomly selected samples having no sampling bias. The sample size needed to be higher than 30, and most importantly, the population standard deviation should be already known.
In most realistic situations, the population standard deviation is often unknown, but in rare circumstances, when it...
Testing a Claim about Mean: Unknown Population SD
Estimating a population mean requires the samples to be approximately normally distributed. The data should be collected from the randomly selected samples having no sampling bias. There is no specific requirement for sample size. But if the sample size is less than 30, and we don't know the population standard deviation, a different approach is used; instead...
