Q: Doing so places your cursor in the cell. Type =STDEV( ) into the cell. You can press the left arrow key once to do this, or you can click in between the two parentheses in the text box at the top of the document. You can input a range of data cells by typing the name of the first cell in the list of data, typing a colon, and typing in the last cell name in the column. For example, if your list of numbers goes from cell A1 through cell A11, you would type in A1:A11 in between the parentheses.  Your completed formula should look something like this: =STDEV(A1:A11)  If you want to calculate the standard deviation of a few numbers (not a whole range), you can type each number's cell name between the parentheses and separate the names with commas. For example, to find the standard deviation of A1, A3, and A10, you would type in =STDEV(A1,A3,A10). Doing so will run your formula, causing the standard deviation value for your selected values to display in your currently selected cell.
A: Click an empty cell. Enter the "standard deviation" formula. Place your cursor in between the parentheses. Add your data range. Press ↵ Enter.

Problem: Article: You'll want around 20 apples for each horse you need to tame. Apples make taming the horses significantly easier (and quicker) than attempting to tame them without food. Horses are typically found in flat, grassy areas such as Plains and Savannas. In your equip bar at the bottom of the screen, make sure you have the apples selected before approaching the horse. Right-click or left-trigger the horse until you stop hearing crunching sounds and the horse starts bucking and neighing. On Minecraft PE, you'll face the horse and tap Feed exactly 20 times. This will allow you to mount the horse. Right-click or left-trigger the horse to do so. You should mount the horse at this point. On Minecraft PE, you'll face the horse and tap Mount at the bottom of the screen. Once red hearts appear around the horse, you have successfully tamed it. At this point, you can dismount by pressing left Shift or the "Crouch" button. If the horse bucks you off, mount it again and wait for the red hearts to appear. You may need to do this several times. You'll need two tamed horses in order to breed them. If your first tamed horse isn't following you around, you can enclose it in a two-block-tall area to keep it from wandering off. You can use any resource (e.g., dirt or sand) to do this, but the wall must be two blocks tall in order to prevent the horses from running away.  If you have enough fencing material in your inventory, you can use that to enclose the horses instead of using blocks. You might want to leave some extra room in the enclosure since you'll be adding a third horse to the mix shortly.
Summary: Gather at least 40 apples. Find a horse. Equip the apples. Select the horse until it stops eating. Switch to an empty hand. Select the horse. Wait for red hearts to appear. Tame another horse. Build a two-block-tall wall around the horses.

Q: Make sure your iron is clean. If your shirt is 100% cotton, set it to high heat. If your shirt is a blend, use low heat.  If the fabric is cotton or polyester and your shirt isn’t still damp from washing, put your iron on a steam setting or have a spray bottle of water ready to dampen the shirt. Don’t use steam if the fabric is silk. Test iron a small piece of fabric on the inside bottom hem before you fully iron your polo shirt. If the high temperature seems too much for the fabric, lower the iron’s temperature. Lay the shirt on the ironing board. Fold the collar down as you would like it to appear. Make sure the collar is damp, then iron it gently. Turn the shirt over and iron the other side of the collar. Spray the collar lightly with starch and iron the collar again. Then turn the collar inside-out, spray starch again, and iron again. This will prevent the collar from curling. Use the point of the iron for the point of the collars and any corners. Use your hands to smooth the shirt down. Also smooth the collar down from the inside. You don’t need to use starch on the body of the shirt. However, you can if you want it to appear stiff, like a button down dress shirt. Lightly spray starch all over both sides of the shirt. Starch can leave white marks on clothes, which is one of the reasons for ironing the shirt inside-out. The other reason is that some fabrics are sensitive to ironing, and this will guard the exterior of your shirt from getting shiny or singed from the iron. Iron the sleeves first, one at a time, by pressing the iron down and smoothing the fabric from the shoulder towards the cuff. Avoid ironing over the edge on the shoulders, or it will form a crease. Next, go over the placket and shoulders with your iron. Iron the chest of the shirt by moving from the center placket towards the shoulders.  Your motions should be continuous. Don’t leave the iron too long in one place. If there are any patches or silk-screened logos on the shirt, avoid ironing those areas. When you’re finished with the top front of the shirt, set the iron to rest on its bottom feet. Move the shirt up so that the front middle is laid out on your ironing board. Begin at the uppermost part of the shirt and move your way downwards with the iron. Repeat this process for the front bottom of the shirt, working downwards towards the hem. Turn the shirt over. It should be on its back and remain inside out. Smooth out the wrinkles, then repeat the process on the entire back of the shirt. Check for wrinkles. Store it on a hanger until it is time to wear it. If you don’t have the closet space, you can fold the shirt.
A:
Set up your iron and ironing board. Iron the collar. Turn the shirt inside out and starch it. Iron the top of the shirt. Iron the middle and bottom of the shirt. Turn the shirt right-side out.
