Day 4 HW 6. Study the patterns in this table. Note that the numbers in the x column may not be consecutive after x 6. a. Use the patterns in the first several rows to find the missing values. b.

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.
I have questions about linear patterns.
I know that there has to be a constant change between the variables but how can I find the next variable with given variables if they don’t look constant, and how can I prove they are not linear ?
