Step 1: Importing the dataset 2021-02-17 Simple Linear Regression Example. Dependent Variable: Revenue Independent Variable: Dollars spent on advertising by city. The null hypothesis, which is statistical lingo for what would happen if the treatment does nothing, is that there is no relationship between spend on advertising and revenue within a city. 2020-03-30 Building Simple Linear Regression Model. Now that we have understood the data, let’s build a simple model to understand the trend between sales and the advertising agent.

Simple linear regression is a technique that we can use to understand the relationship between a single explanatory variable and a single response variable.. This technique finds a line that best “fits” the data and takes on the following form: Simple linear regression is used for three main purposes: 1. To describe the linear dependence of one variable on another 2. To predict values of one variable from values of another, for which more data are available 3. To correct for the linear dependence of one variable on another, in order to clarify other features of its variability. Welcome to this article on simple linear regression.
