In other hand, emergence of multiple data sources has increased the demand of these factors, together for...

Teaching Basic Probability and Statistics Using Computer Graphics

In the physical sciences it has been long known that the most effective way to teach students is by having them "discover" the basic principles themselves. Unfortunately, probability and statistics have traditionally not been taught this way. With the advent of the persona1 computer, all that has changed. Microcomputers can do more than take the drudgery out of calculations. Their unique graphi...

Note Set 1: Review of Basic Concepts in Probability

Consider a variable A that can take a finite set of values {a1, . . . , am}. We can define a probability distribution for A by specifying a set of numbers {P (A = a1), . . . , P (A = am)}, where 0 ≤ P (A = ai) ≤ 1 and where ∑m i=1 P (A = ai). We can think ofA = ai as an event that either is or is not true, and P (A = ai) is the probability of this particular event being true. We can also think ...
