Session 1: Statistical Variation and the Normal Curve
... Perhaps the most striking feature of observation or real data values from almost any discipline is the variation they exhibit. If a nurse measures physical dimensions (heights, weights..) or blood parameters (Serum albumin or cholesterol..) for a sample of patients, they will (nearly) all be differe ...

Solutions to the Exercises
... (b) The assumption of independence reduces, in this case, to saying that whether a patient drops out of the placebo group is unaffected by what happens to other patients in the group. Sometimes patients are unaware of others' progress in this sort of trial; but otherwise, it is at least possible tha ...

... and ANOVA inferences that assume equal spread will be valid), a rule of thumb is to look at whether the ratio of the largest sample standard deviation to the smallest sample standard deviation is less than two. Here the ratio is 7.77/5.13 = 1.51 < 2. Thus, the ttests and ANOVA analyses should be app ...

28 Data handling and statistics PowerPoint
... Statistics is concerned with the collection, ordering and analysis of data. Data consists of sets of recorded observations or values. Any quantity that can have a number of values is a variable. A variable may be one of two kinds: (a) Discrete – a variable whose possible values can be counted (b) Co ...
