Confidence Intervals, Part 1: Assessing the Accuracy of Samples
... Computing confidence intervals In the first part of the discussion we shall leave aside the issue of estimating the extent of the dispersion—a troublesome matter, but one which seldom will result in unsound conclusions even if handled crudely. To start from scratch again: The first— and seemingly st ...

... numerical methods. For d > 2, we investigated suitable modifications of rule (7) and behaviors similar to those described in Section 3.2 were noticed for d = 3, 4. On the other side, the normal approximation used in Section 3.1 is available in closed form only for d = 2. The existence of such an app ...

... It usually happens that about 2/3 of random samples (a.k.a. students) are within one standard deviation of the mean. So a convenient curving scheme works by setting mean to a certain grade and every standard deviation away as another grade. EG: A typical Columbia curving scheme: D’s ...

Here is the reduction: Alice transforms a ∈ {0, 1}n into a distribution x over [3n] by applying the following rule for each i ∈ [n]: if ai = 1 then x3i = 1/n and ...
