Introduction to Applied Statistics Chapter 4 Objectives: I. Discuss the language of mathematics A. ‘A’ and ‘B’ and ‘X’ and ‘Y’ are used to represent a quantity, score, or value within a variable. ‘N’ is used to represent a number of something. II. Distinguish between the independent variable and dependent variable A. An independent variable is the main variable that is used to determine if it has an effect on another variable (the dependent variable). The dependent variable can only be determined by the independent variable and relies on that for its outcome. (ie: “Is number of pounds overweight related to systolic blood pressure” The number of pounds overweight would be the independent variable and blood pressure would be the dependent variable because the blood pressure is depending on how much overweight a person may be.) III. Distinguish between descriptive and inferential statistics A. Descriptive statistics classifies numerical data (ie: how many students are in the classroom How many are male How many are female) Inferential statistics makes a guess about the population based on a smaller portion of the population (a sample.) IV. Describe the types of data that can be collected A. Nominal data is a name or category. It is simply an identificatio
