Years Marmara Sea Black Sea Mediterranean Sea According to meteorological data, the average monthly seawater temperatures of three different seas between 1970-2018 are given. Accordingly, draw the graph showing the change of seawater by years for each sea and find the equation of the line that best 1970 15,3 15,4 21 1974 14,8 14,9 21 1978 15 14,8 21 1982 14,8 15 20,7 1986 15,1 14,8 21,5 1990 15,9 14,7 21,2 represents the data for each sea and calculate the correlation coefficients, as well. 1994 16,8 14,8 21,4 1998 14,9 15,1 21,7 2002 15,9 15,7 21,9 2006 15,4 15,4 21,7 2010 16,3 16,2 22 2014 16,7 16,2 22 2018 17,4 16,5 22,4
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.
