An upper-level math course is open to both undergraduate students and graduate students. The table below gives the performanc of the two level of students in the class last semester on the final exam. Score, S, on Final Exam S< 70 70 s S< 80 80 sS< 90 90 s Ss 100 Total Undergraduate 16 14 17 3 50 Graduate 10 19 7 40 Total 20 24 36 10 90 Given that a student scored below 80, find the probability that the student was an undergraduate student. Give the probability as a decimal. If rounding, give to 4 decimal places. The probability is
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.
Formula:
P(A|B) =
