Its origins trace back to an early terminal-based student information system used at Western New England College. In that system, we were able to call up a course roster that would be displayed on the terminal in pretty much the same format as the roster file now supported by Manhattan. The format continues to be supported, and is a reasonable choice because it's easy to type by hand, or to generate from a student information database.

The categories can be unordered or ordered see below.

Counts and Proportions Counts are variables representing frequency of occurrence of an event: Number of students taking this class. Number of people who vote for a particular candidate in an election. Number of students taking this class divided by the total number of graduate students.

Number of people who vote for a particular candidate divided by the total number of people who voted. Discretely measured responses can be: Nominal unordered variables, e.

Measurement Scale and Context Interval variables have a numerical distance between two values e. For example, methods specifically designed for ordinal data should NOT be used for nominal variables, but methods designed for nominal can be used for ordinal.

However, it is good to keep in mind that such analysis method will be less than optimum as it will not be using the fullest amount of information available in the data.

Consider majors in English, Psychology and Computer Science. The context of the study and the relevant questions of interest are important in specifying what kind of variable we will analyze. For example, Did you get a flu? Yes or No -- is a binary nominal categorical variable What was the severity of your flu?

Low, Medium, or High -- is an ordinal categorical variable Based on the context we also decide whether a variable is a response dependent variable or an explanatory independent variable.

Discuss the following question on the Course Discussion Board: Why do you think the measurement hierarchy matters and how does it influence analysis? Here are a few simple examples of contingency tables. Admissions Data A university offers only two degree programs: English and Computer Science.

Admission is competitive and there is a suspicion of discrimination against women in the admission process.

Here is a two-way table of all applicants by sex and admission status. These data show an association between the sex of the applicants and their success in obtaining admission.Write the following set in roster form.

Solving linear equations using elimination method. Solving linear equations using substitution method. Solving linear equations using cross multiplication method. Word problems on simple interest. Word problems on compound interest. You use lambda expressions to create anonymous methods.

Sometimes, however, a lambda expression does nothing but call an existing method. In those cases, it's often clearer to refer to the existing method . When talking about sets, it is fairly standard to use Capital Letters to represent the set, and lowercase letters to represent an element in that set.

So for example, A is a set, and a is an element in A. Same with B and b, and C and c. Using the subset symbol we can write this same fact much more efficiently as use the roster method to specify the set.

of the three graphs depends on the number of real solutions of the equation and can be determined with one or two simple tests. Practice the worksheet on sets in roster form to write a set using the roster or tabular method.

We know, to express the set in roster form the elements of a set are listed within the curly brackets and are separated by commas. Now, let's practice the questions given in the worksheet on sets in Roster form.
