How to fill out least squares linear regression

1. To fill out a least squares linear regression, you need to start by gathering your dataset. This dataset should consist of pairs of inputs (x) and corresponding outputs (y) that you want to analyze and find a linear relationship between.
2. Next, calculate the means of both the x and y values. This will give you the average values for each variable, which will be used in further calculations.
3. Now, calculate the deviations of each x value from the mean of x and the deviations of each y value from the mean of y. These deviations will represent how much each data point differs from the average.
4. Multiply the deviations of x and y for each data point to obtain the product of deviations for each point.
5. Calculate the sum of these product of deviations for all the data points.
6. Calculate the squared deviations of x. This involves taking each deviation of x, squaring it, and summing up all the squared deviations.
7. Using the sum of squared deviations of x, calculate the slope of the regression line, also known as the coefficient of x. This can be done by dividing the sum of the product of deviations by the sum of squared deviations.
8. Calculate the intercept of the regression line, also known as the y-intercept. This can be found by subtracting the product of the slope and the mean of x from the mean of y.
9. Once you have the slope and intercept, you can write the equation of the regression line in the form of y = mx + b, where m is the slope and b is the intercept.
10. Least squares linear regression is used by individuals, researchers, and businesses in various fields such as economics, finance, social sciences, engineering, and many others. It is particularly helpful for those who want to understand and analyze relationships between variables, make predictions based on trends, or identify factors that influence an outcome based on historical data.
