onstruct a spreadsheet simulation model to simulate 500 rolls of a die with the six sides numbered 1, 2, 3, 4, 5, and 6. Construct a histogram of the 500 observed dice rolls. For each roll of two dice, record the sum of dice. Construct a histogram of the 500 observations of the sum of two dice. For each roll of three dice, record the sum of dice. Construct a histogram of the 500 observations of the sum of three dice. For each roll of four dice, record the sum of dice. Construct a histogram of the 500 observations of the sum of four dice. Compare the histograms in parts a, b, c, and d. What statistical phenomenon does this sequence of charts illustrate?
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.
