4. Use the scatterplot below to answer the following question. Parking Tickets 10 15 20 Number of Ticket Writers The traffic enforcement agency tracked the number of ticket writers and number of tickets issued for 8 weeks. The scatterplot shows the results. Based on the graph, highlight all of the true statements. A. There is a positive correlation because more ticket-writers results in fewer tickets issued. B. There were 600 tickets issued in week 9. C. Going from 6 to 10 ticket-writers, results in about 200 more tickets issued. D. There is a positive correlation because more ticket-writers results in more tickets issued. Number of Tickets Issued (in hundreds)
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.
