Mason students on each campus were asked: Where were you born? The results are summarized below: Other(O) International (I) Campus Fairfax(F) Arlington(A) Virginia(V) 250 150 180 60 35 25 155 45 15 Sci-Tech(S) For each of the following, assume random selection Your responses MUST include the probability notation (e.g., P(V|A) = 60/120)) a. What is the probability of selecting a student who was born in Virginia? b. If the student selected is a Fairfax student, what is the probability that the student was born in Virginia? c. If the student selected was born in another state, what is the probability that the student is an Arlington student? d. If the student selected is an Arlington student, what is the probability that the student was born in another state? e. Are International and Fairfax independent events? You must use a formula for independent events.
Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
