A board member of the fire prevention task force gathered the following information showing the average temperature in a month and the number of fire incidence in a certain city last year? Temp in 26 degree Celsius 27 30 32 34 36 29 28 26.5 25 26.7 24 Number 5 7 7 10 9 8 4 5 7 4 3 4 3 of fire incidence 7. What is the dependent and independent variable based on the problem Answer is letter B 8. What are the slope and the y intercept of the given data A. B1=-10.7009, bo = 0.5735 B. B1 = 10.7009, BO = 0.5735 C. B1 = 0.5735, BO = -10.7009 D. B1 = -10.7009, BO = -0.5735 9. Considering the computed slope and y intercept, how would you know the model the equation of the regression line 10. How many fire incidence are there if the average temperature is 33.5 degrees celcius?
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.
