P(B | A) = the probability that event B will happen, given that event A definitely happens. It’s usually read as the probability of B given A. Defined here in Chapter 5. Caution! The order of A and B may seem backward to you at first. The Z score, also known as the "standard score", is the number of standard deviations away from the mean you particular observation is. For example, if the mean is 10, with a standard deviation of 2, and the observation is 14, the z score is 2, since you are 2 standard deviations above the mean. It works the same way below the mean.MATLAB does that automatically in this case.

In the world of mathematics, the letter “Z” is used to represent the set of all integers, also known as the set of whole numbers. This includes both positive and negative numbers, as well as zero. You might be wondering why the letter “Z” was chosen to represent this set.As we have already discussed, in mathematics set theory, a set is a collection of different types of objects, and collectively it is called an object. For example, numbers 8, 10, 15 and 24 are 4 distinct numbers, but when we put them together, they form a set of 4 elements, such that {8, 10, 15, 24}. A z-score measures the distance between a data point and the mean using standard deviations. Z-scores can be positive or negative.
