To determine a) Whether the diagram shows a positive correlation , a negative correlation , or no correlation. And also to describe if there is a positive or negative correlation, it is strong or weak. Explanation Given: Correlation : A correlation is a special type of relationship between variables, in which a rise or fall in one goes along with a corresponding rise or fall in the other. Establishing a correlation between two variables does not mean that a change in one variable causes a change in the other. A correlation is defined as a relation, which exists between two variables when higher values of one variable consistently go with higher values of another variable or when higher values of one variable consistently go with lower values of another variable. Types of Correlation: When the increase in one variable ( X ) is followed by a corresponding increase in the other variable ( Y ) or vice-versa, then the corresponding correlation is said to be positive correlation. The positive correlation range from 0 to + 1 , where + 1 is the perfect positive coefficient of correlation. In the perfect positive correlation, every unit increase in one variable result in every unit increase in the other variable. On the other hand, if the increase in one variable ( X ) results in a corresponding decrease in the other variable ( Y ) or vice-versa, then the corresponding correlation is said to be negative correlation... To determine b) The conclusion from the diagram.

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 p…

3. Bayesian Inference – Updating Beliefs A medical test for a rare disease has the following characteristics: Sensitivity (true positive rate): 99% Specificity (true negative rate): 98% The disease occurs in 0.5% of the population. A patient receives a positive test result. Questions: a) Define the relevant events and use Bayes’ Theorem to compute the probability that the patient actually has the disease.b) Explain why the result might seem counterintuitive, despite the high sensitivity and specificity.c) Discuss how prior probabilities influence posterior beliefs in Bayesian inference.d) Suppose a second, independent test with the same accuracy is conducted and is also positive. Update the probability that the patient has the disease.
