From this chart, we can see a clear relationship.
This will add a linear trend line to the chart, and it looks like this. Click on the drop-down list of Add Chart Element > Trend line > Linear.
Under the Design tab, go to Add Chart Element. Regression is great for use for using Excel for statistical data analysis. Select the chart to see two new tabs in the ribbon, Design and Format. Regression is a process of establishing a relationship among many variables to establish a relationship between dependent variables and independent variables.

It is widely used for using Excel for statistical data analysis. In Windows Excel I have used the Data Analysis Tool to do multiple regressions, but that is not available in Excel 2011 for the MAC. Lastly, select "Display R-squared value on chart". Regression is one of the best features in Excel. It can also run the five basic Statistical Tests.

To add the R 2 value, select "More Trendline Options" from the "Trendline menu. How To Run Statistical Tests in Excel Microsoft Excel is your best tool for storing and manipulating data, calculating basic descriptive statistics such as means and standard deviations, and conducting simple mathematical operations on your numbers. In the dialog box, select "Trendline" and then "Linear Trendline". To add a regression line, choose "Layout" from the "Chart Tools" menu. We can chart a regression in Excel by highlighting the data and charting it as a scatter plot. Because the Regression tool generates many outputs on a single sheet, you may want to use Excel’s Zoom Control option to reduce the new worksheet size in order to get a view of how the outputs are arranged. Click any cell to turn off the range selection. The time period under study may not be representative of other time periods. Excel completes the regression analysis leaving a large range of the worksheet selected.The data is a time series, so there could also be autocorrelation.There are only 20 observations, which may not be enough to make a good inference.Visa is a component of the S&P 500, so there could be a co-correlation between the variables here.With only one variable in the model, it is unclear whether V affects the S&P 500 prices, if the S&P 500 affects V prices, or if some unobserved third variable affects both prices.However, an analyst at this point may heed a bit of caution for the following reasons: From the R-squared, we can see that the V price alone can explain more than 62% of the observed fluctuations in the S&P 500 index.This indicates that this finding is highly statistically significant, so the odds that this result was caused by chance are exceedingly low. We can also see that the p-value is very small (0.000036), which also corresponds to a very large T-test.In the regression output above, we can see that for every 1-point change in Visa, there is a corresponding 1.36-point change in the S&P 500.The bottom line here is that changes in Visa stock seem to be highly correlated with the S&P 500.
