How to use LINEST function in Google Sheets?

To use the LINEST function in Google Sheets, follow these steps:

1. Open Google Sheets: Go to Google Sheets and open the spreadsheet where you want to use the LINEST function.
2. Enter Data: Enter your data in two columns. For example, you might have X values in column A and corresponding Y values in column B.
3. Insert Formula: Click on the cell where you want to display the LINEST results. Then, type the following formula:
   Copy code=LINEST(B2:B10, A2:A10, true, true) Replace B2:B10 with the range of your Y values and A2:A10 with the range of your X values. The true, true at the end of the formula tells Google Sheets to include the intercept and display the additional statistics.
   
4. Press Enter: After entering the formula, press Enter. Google Sheets will calculate the LINEST statistics and display them in the selected cell.
5. Review Results: The LINEST function will return an array of values representing the slope, y-intercept, correlation coefficient, standard error, and other statistics related to the best-fit line for your data.

That’s it! You’ve successfully used the LINEST function in Google Sheets to calculate statistics for a best-fit line.
