It can tell us the environmental consequences of pollution, but whether these consequences are “good” or “bad” is a judgment that we make based on our values, or goals, not on science.

best practice guide on statistical analysis of fatigue data
... Fatigue testing is the main basis of the relationship between the fatigue resistance of a given material, component or structural detail and cyclic loading. The results of such fatigue endurance tests are plotted on graphs relating applied loading (force, stress, strain, etc) and the number of cycle ...

PERT Schedules Modeled using Beta Distribution
... Using derived PERT parameters for Mean and Std.Dev. for rapid estimation, there is a 95% confidence that the schedule will be between Mean ±2xStd.Dev. This is certainly acceptable if the shape is as indicated in Figure 1. This is the typical shape since most scheduled tasks/projects complete later t ...

Tests of Hypotheses Using Statistics
... The method of hypothesis testing uses tests of significance to determine the likelihood that a statement (often related to the mean or variance of a given distribution) is true, and at what likelihood we would, as statisticians, accept the statement as true. While understanding the mathematical conc ...

The variety of such pictures (these two as well as other possible ones) is too great for us to devote more time to the topic. Thus, I propose the following agreement between you and ...
