Laura is a human resources director for a manufacturing plant. She has become concerned with the number of safety violations that have been reported by supervisors. She decides to start a safety seminar that all employees will need to attend. Using her computer, she creates a spreadsheet that will track the number of violations over the next six months as all employees attend the seminar. The x-axis will represent the number of employees who have completed the seminar and the y-axis will represent the number of safety violations reported. The spreadsheet will automatically create a scatterplot with a line of best fit. What does she hope to see as she implements her plan? O a positive correlation, indicating safety improvement O a negative correlation, indicating safety improvement O no correlation, indicating safety improvement O a curving line that starts out as a positive correlation and turns negative to indicate safety improvement

Concept explainers

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.
