Concept explainers

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…

Textbook Question

Chapter 5.E, Problem 32E

Correlation and Causality. Consider the following statements about a correlation. In each case, state the correlation clearly (for example, there is a positive correlation between variable A and variable B). Then state whether the correlation is most likely due to coincidence, a common underlying cause, or a direct cause. Explain your answer.

In a volatile housing market, the overall value of a home can be modeled by V(x) = 415x² - 4600x + 200000, where V represents the value of the home and x represents each year after 2020. Part A: Find the vertex of V(x). Show all work. Part B: Interpret what the vertex means in terms of the value of the home.

Show all work to solve 3x² + 5x - 2 = 0.
