The ratio of the residual sum of squares versus the total SS should be smaller if most of your data fits the regression line. df: Statistical value known as degrees of freedom related to the sources of variance.The remaining values in the regression output give you details about smaller components in the regression analysis. Observations: The number of observations in your regression model.If this error is small then your regression results are more accurate. Standard Error: How precise the regression analysis results are.Adjusted R Square: A statistical value called R square that's adjusted for the number of independent variables you've chosen.Statistically, this is the sum of the squared deviations from the mean. R Square: The Coefficient of Determination, which shows how many points between the two variables fall on the regression line.1 indicates a strong correlation between the two variables, while -1 means there's a strong negative relationship. Multiple R: The Correlation Coefficient.It doesn't get more productive than that! Along those lines, we also recommend checking out these other must-learn Excel tips.Each of these numbers has the following meanings:
You can also use Quick Analysis to preview and make charts and tables in the blink of an eye. I first found out about Quick Analysis when I was tracking the nutritional information of everything I ate - and the Sum feature was so useful in quickly summing up and previewing a day's worth of food without having to use permanent equations and functions. If you want the preview to become real, click instead of hover.
In the Totals category you can hover over Sum to see the summed value of all columns in your selection. Upon clicking, you'll see several types of possible analyses.įor example, in the Formatting category you can hover over Data Bars to preview all numeric cells filled proportionally by data value. Open a spreadsheet that has data in it, select a group of cells, then click on the icon that shows at the bottom-right corner of your selection (this is the Quick Analysis button). Using the Quick Analysis function is dead simple.
