would you conduct a correlation coefficient after gathering the data? Why or why not?
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.
If you were interested in whether adults who have children communicate less with their friends compared to adults without children (based on the number of conversations recorded), would you conduct a
Correlation coefficient definition : Correlation coefficient is measure of extent of linear relation between two variables X and Y .and it is denoted by rho and it estimate by r .
from above ,our X variable is adults who have children communicate less with their friends , and Y variable is who do not have children communicate less with their friends, Here we find the Correlation coefficient between two variables X and Y. and also there linear relationship.
