概括
左位数效应,即像19和22这样的数字看起来比实际相距更远,在无限数列任务中持续存在. 这表明这种效应不仅仅是由于特定的任务策略.
科学领域:
- 认知心理学 认知心理学
- 数字认知 数字认知
背景情况:
- 左位数效应描述了不同首位数的数字之间的距离的高估 (例如,19与22).
- 之前的研究主要利用边界数列任务来研究这种现象.
研究的目的:
- 在无限数行任务中调查左数字效应的存在和强度.
- 确定效果是否取决于在受界数行任务中使用的特定任务策略.
主要方法:
- 一项预先注册的研究,涉及58名大学生.
- 参与者完成了一个无限数列任务,目标数字在0到100之间,跨越多个块.
- 数据收集的重点是数字估计的准确性和响应模式.
主要成果:
- 观察到一个统计可靠的中等大小的左手指效应 (d = 0.70).
- 研究结果表明,左数字效应并不仅限于边界数列任务.

01:17Sign Test for Matched Pairs

The sign test for matched pairs offers a robust method for comparing two paired samples, often for the effects of an intervention in one of them. This method is very useful in situations where the underlying distribution of the data is unknown. The test compares two related samples—often pre- and post-treatment measurements on the same subjects—to determine if there are significant differences in their median values.
To conduct the sign test, we first calculate the differences in...

03:34Uncertainty in Measurement: Significant Figures
63.0K
All the digits in a measurement, including the uncertain last digit, are called significant figures or significant digits. Note that zero may be a measured value; for example, if a scale that shows weight to the nearest pound reads “140,” then the 1 (hundreds), 4 (tens), and 0 (ones) are all significant (measured) values.
