MULTIPLE CHOICE 1. A statistical technique that enables you to obtain a linear equation that relates dependent variable with the independent variable is called 2. Which of the following is not true about scatter plot? A. It is visual tool that can help in analyzing the relationship between two variables in bivariate data B. Itis a graph that shows the point (sa) plotted in the 3x plane that corresponds to the recorded values in data c. The independent variable is associated with the x-axis and the dependent variable is associated with the y axis D. Scatter plots are the most inefficient form of graphing bivariate data
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.
