First, consider deliberate thinking. Deliberate thinking is relatively slow, rule-based and explicit; a contemplative process of weighing pros and cons, gathering scientific or statistical evidence. It would appear that this makes for pretty solid decision-making.
Jul 24, 2015. Outliers increase the standard deviation. Mean is most affected by outliers, since all values in a sample are given the same weight when calculating mean. A value that is far removed from the mean is going to likely skew your results and increase the standard deviation. Say you have five values: 2, 1, 2, 1.5, and 2.1.
For example, a large standard deviation creates a bell that is short and wide while a small standard deviation creates a tall and narrow curve. To understand the probability factors of a normal distribution you need to understand the following ârulesâ: 1. The total area under the curve is equal to 1 (100%). 2. About 68% of the area under the curve falls within 1 standard deviation.
