You can sort in ascending or descending order.Ģ Filter: Filter your Excel data if you only want to display records that meet certain criteria.ģ Conditional Formatting: Conditional formatting in Excel enables you to highlight cells with a certain color, depending on the cell's value.Ĥ Charts: A simple Excel chart can say more than a sheet full of numbers. This is also referred to as sum of squared errors.Īll of the variation in our response can be broken down into either model sum of squares or error sum of squares.1 Sort: You can sort your Excel data on one column or multiple columns. This is the variation that is not explained by our regression model. For each observation, this is the difference between the response value and the predicted value.

The error sum of squares, or SSE, is a measure of the random error, or the unexplained variation.

Note that sometimes this is reported as SSR, or regression sum of squares.

This is the variation that we attribute to the relationship between X and Y. For each observation, this is the difference between the predicted value and the overall mean response. The model sum of squares, or SSM, is a measure of the variation explained by our model.For each observation, this is the difference between the response value and the overall mean response. The total sum of squares, or SST, is a measure of the variation of each response value around the mean of the response.The total variation in our response values can be broken down into two components: the variation explained by our model and the unexplained variation or noise.
