With each sample point we can associate a number for X as shown in Table 2-1. Thus, for example, in the case of HH (i.e., 2 heads),X 2 while for TH(1 head) ,X 1. It follows that X is a random variable. CHAPTER 2 Sample Point HH HT TH TT X 21 1 0 Table 2-1 It should be noted that many other random variables could also be defined on this sample space, for example, the square of the number of

How to Create a Frequency Table

Frequency tables can quickly reveal outliers and even significant trends within a data set with not much more than a cursory inspection. For example, a teacher might display students’ grades for a midterm on a frequency table in order to get a quick look at how her class is doing overall.

BIVARIATE DISTRIBUTIONS Let x be a variable that assumes the values {x 1,x 2,…,x n}. Then, a function that expresses the relative frequency of these values is called a univariate frequency function. It must be true that f(x i) ≥ 0 for all i and i f(x i)=1. The following table provides a trivial example: x f(x) −1 0.25 1 0.75 Let x and y be variables that assume values in the the sets {x

The frequency distribution in Table 3.2 reveals more information about the data than a quick look at the 25 numbers. For example, from the frequency distribution, we learn that more

Frequency Distributions Frequency tables are used to organize a large set of quantitative data into something easier to understand. Frequency tables can be constructed to show individual data values (x) and the number of times each value occurs or frequency, f(x). This is an ungrouped frequency distribution. Frequency tables can also be constructed by breaking data into smaller classes
