Document Summary
What is robustness: this means that a certain value of the data is resistant to a slight change in the data set, ex. Independence: check independence of events a and b by either, p(a|b)= a or, p(a b)= p(a)p(b, if either equation is found to be equal, then the events are independent. Mutually exclusive: when two or more events can"t happen together at all, when at most 1 of the two events can happen at a time, ex. In a venn diagram circle a and circle b are two separate circles which don"t share a middle. Density curve: properties, all numbers are greater or equal to zero, total area under the curve equals 1, can be divided into sections to show the amount of data in % form is contained in that area. Variables that take numerical values depending on the outcome of a random experiment: can be either, discrete, continuous.
