1.50 Gulf Oil Spill Cleanup On April 20, EXO150 2010, the United States experienced a major environmental disaster when a Deepwater Horizon drilling rig exploded in the Gulf of Mexico. The number of personnel and equipment used in the Gulf oil spill cleanup, beginning May 2, 2010 (Day 13) through June 9, 2010 (Day 51) is given in the following table." Dala Day 13 Day 26 Day 39 Day 51 Number of personnel (1000s) 3.0 Federal Gulf fishing areas closed 3% 46 156 1.0 17.5 8% 315 500 6.0 20.0 25% 644 870 14.0 24.0 32% 909 1143 35.0 Booms laid (miles) Dispersants used (1000 gallons) Vessels deployed (100s) a. What graphical methods could you use to display these data? b. Before you draw your graphs, what trends do you see in each of the variables displayed? c. Use a line chart to display the number of personnel deployed over this 51-day period. d. Use a bar graph to display the percentage of federal Gulf fishing areas closed. e. Use a line chart to display the amounts of dispersants used. Is there any underlying straight line relationship over time?
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.
