Q: Calculating volatility is much simpler and faster in Excel than it is by hand. Start by opening Microsoft Excel on your computer and opening a blank worksheet. The next step is to import the closing prices for the stock you are measuring. Input the closing prices vertically in the A column, with the oldest price first and the most recent price at the bottom. For example, 21 days' worth of prices would go in cells A1-A21. Interday returns are simply the difference between the closing prices of consecutive days. The results of this calculation will go in the cells adjacent to the closing prices, in column B. Calculate these returns by entering the following formula in cell B2: =(A2/A1)-1. This will calculate the percent changes between day 1 and day 2 of your range. Then, drag the formula down the rest of your range to the last price. You should now have a list of interday returns in column B. To calculate volatility, all you have to do now is use the standard deviation function. In a nearby cell (it doesn't matter where, as long as it's empty) enter the following function: "=StdDev(". Then, fill in the parentheses with your interday return data from column B. For example, if your data is contained in cells B2 to B21, enter: =StdDev(B2:21). Remember to close the parentheses. Pressing enter on the cell containing this function will give you the volatility of the stock over your chosen time range.
A: Set up your spreadsheet. Input market information. Calculate interday returns. Use the standard deviation function.

Q: Remove the lard from the heat source and allow it to cool to a lukewarm temperature. It is very important that you wait until the lard has a chance to cool slightly before pouring it into glass jars. Hot lard can cause the glass to weaken, crack, or break. Ladle the rendered fat through a fine-mesh sieve to remove any solid pieces, leaving you with nothing but liquid lard. Alternatively, pour the fat through a paper coffee filter wedged inside of a cone or funnel, or through a piece of cheesecloth draped inside a colander. You can pour the lard into a separate bowl or directly into your intended storage containers. Transfer the filtered lard into glass jars, then tightly twist a lid onto each jar. If the jars feel warm to the touch, let them sit out on your counter for another few hours until the sides feel cool. The idea is to make the temperature change as subtle as possible to prevent that glass from becoming damaged. You can use lard in the same way you would use butter or shortening. If you want to use the lard in a recipe that usually calls for oil, you will need to melt it down into a liquid form.
A: Let the lard cool. Remove any remaining chunks. Pour the lard into jars. Use as you would use any other solid cooking fat.

Q: If you aren't seeing a new version but you know that there is one available, you may need to adjust your Software Updater settings. Open the Ubuntu Software Center. Click "Edit" "Software Sources". Click the "Updates" tab. Find the "Release upgrade" section or "Notify me of a new Ubuntu version". Select "Long term support releases only" or "For long-term support versions". Problems with the upgrade process typically stem from running an outdated and unsupported version of Ubuntu. You'll need to either upgrade to each subsequent version until you reach the one you want, or you'll need to perform a fresh install of Ubuntu.
A: The Software Updater utility does not show a new version available. The upgrade process is failing, or the Software Updater won't allow upgrading to the newest version.

Q: appears. The menu that appears is known as the Windows 8 "Charms" bar. If you had other programs running before starting, some may prevent the process from proceeding. If this is the case click the Restart Anyway option.
A:
Move your cursor to the top or bottom right corner of the screen. Click Settings. Click the Power button. Click Restart.
