I just do not understand this process, any help is greatly appriciated. LINEAR CORRELATION PROJECT / Topic: Does per capita income affect birth rates Construct a hypothesis (remember for a sample size of 20, the absolute value of r should be greater than 0.45) Country Per Capita Income Average Birth Rate Afghanistan $ 530 37.9 Austria $ 51,460 9.5 Cambodia $ 1,530 23 Canada $ 46,370 10.3 Denmark $ 63,950 10.5 Ecuador $ 6,090 17.9 France $ 42,450 12.2 Haiti $ 1,330 23 India $ 2,120 19 Kenya $ 1,750 23.9 Monaco $ 186,080 6.6 Nigeria $ 2,030 36.9 Peru $ 6,740 17.8 Philippines $ 3,850 23.7 Russia $ 11,260 11 Serbia $ 7,030 9 South Africa $ 6,040 20.2 Turkey $ 9,690 15.7 United States $ 65,850 12.5 Venezuela $ 13,080 18.8
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.
