Video transcript - [Instructor] What we have here is a visual depiction of a function. When you study one variable, you are performing a univariate analysis. The next day, 25 students attend class, and so on. Statistical analysis is defined by studying the relationship between variables and can by univariate, bivariate or multivariate analysis. In the following sections, you’ll learn about how even within these two types of variables, there are different types of values. Is the domain discrete or continuous? This is “c”. 3 pennies each day implies that he won't be given 1.5 pennies each half day, etc. A.12 Number and algebraic methods. Can we think of a "joint distribution" of two random variables where one random variable has a continuous density function and the other is discrete? Continuous data is considered as the opposite of discrete data. You are in charge of reserving hotel rooms for a baseball team. Meaning, it is a number with an identified minimum and maximum. -Lecture Notes (PDF, PowerPoint, and SMART Notebook) This is a matching worksheet. While both functions look very similar in their structure, one question often arises: Are both functions continuous? These posters are designed to fit the NGSSS curriculum, but will align with many Common Core standards. 2 ACTIVITY: Discrete and Continuous Domains a. The number of notes is continuous; the length of the note held is discrete. We do this as a precursor to domain and range, because they are notated differently. Listen for students who are starting to understand this difference (in the first problem the number of days is discrete. Now that you know the most common types of variables, it’s important to note what kind of statistical analysis you can perform.
