Click the top value in cell A to select it, then hold down Shift while clicking the C cell that's across from the bottom-most A cell that has a value in it. This will highlight all of your data and the corresponding bin numbers. It's a tab in the green Excel ribbon at the top of the window. You'll find this in the "Charts" section of the Insert toolbar. Doing so will prompt a drop-down menu. It's the set of blue columns below the "Histogram" heading. This will create a histogram with your data and bin numbers. Be sure not to click the "Pareto" icon, which resembles blue columns with an orange line. Before saving, make sure that your histogram looks accurate; if not, consider adjusting the bin numbers and redoing the histogram. Press Command+S, enter a name, select a save location if necessary, and click Save.

Wood stain can highlight the natural hues of the wood or it can give your floor a unique, colorful twist. If you are already happy with the color of the hardwood, you do not need to stain the floor. Move on to waxing and buffing the floor or apply a clear polyurethane finish. When picking a stain brand, value quality over quantity; don't be afraid to spend 40 or 50 dollars on a gallon. When choosing a color, keep in mind that the stain will look very different over an entire room than it did on the sample chart. Understand that the color will soak into the wood and fade slightly. Pick a finish that goes well with the room, and pick one that you're willing to live with for a long time. Depending on the brand, you will need 12 gallons (3.87.6L) of stain for an average floor. If you are attempting this for the first time, get a water-based stain: it is much easier to work with. Get a staining pad head with a detachable extension. The cheapest way is to get the replaceable pads. If you're using a semi-transparent stain, be sure to get the soft white fiber for staining, as the paint-specific pads will apply all but the solid color stain unevenly. A darker stain color can help cover up stains like dog urine that have seeped into the wood and won't come out with sanding. This will prevent uneven coverage. Ask at your local hardware store or flooring specialist; they should be able to direct you to the right product. After 10-15 minutes, use a rag to wipe away any excess stain. Pour as much stain as you will need to work with into a bucket and stir it thoroughly. This will also help to ensure even coverage. don't let the layer get too thick; you want a thin, even layer that will dry smoothly. Apply a small amount of stain to a small test area. The color may vary considerably from the display at the store. Be sure to stir the stain regularly during the application process. Avoid leaving a stain or water spill on the wood: it will stain and rot if left unattended. Allow ample drying time between each coat. Water-based stains need to dry for 2-6 hours, and oil-based stains need to dry for 6-10 hours. As it dries, you will have a better idea of whether you want another coat. You will probably need at least two coats of stain to reach the exact shade that you chose. You can get a softer finish for a natural-looking protective barrier, or a semi-gloss finish to make your new floor really shine. Use the same process to apply. Use a paint roller to evenly spread the polyurethane across the floor. Let it dry completely. Consider rolling out an extra coat for added protection and shine. If you do not want to use polyurethane, you can choose to wax and buff the floor instead. Try to stick to the base you used for the floor: if you chose a water-based stain, then be sure to use a water-based polyurethane clear-coat. Once you've applied the polyurethane coat, do not walk on the floor for 24 hours (or as long as the urethane packaging says that it needs to dry). If you walk on the floor before the coat is completely dry, you might smudge the gloss and leave unsightly blemishes across your hardwood. Do not steam-mop the floor for at least a month after finishing.

Summary: Decide whether or not you want to stain your floor. Choose a stain. Apply a durable floor sealant to the hardwood prior to staining it. Stain the floor generously using a brush, a rag or a roller. Add as many additional coats as you need to achieve your desired result. Consider using a polyurethane clear-coat.

Many years ago, most workplaces were made with wood floors, which have some cushioning even though they may seem pretty hard to walk on. However, in modern times, most businesses tend to have floors made from concrete, ceramic tile or marble, which have essentially no cushioning, shock absorbency or insulative properties. Consequently, stand in an area that's covered in more springy material such as wood. If that's not possible, then change positions just for the exercise, which will promote blood circulation and may ease the tension in your feet and leg muscles. Concrete and ceramic tile will easily transfer cold to your feet which is not good for blood circulation, so stand in warmer areas without cool drafts. If you work outside, find some grass to stand on while plying your trade or waiting for the next task. Anti-fatigue mats are designed to decrease the stress on your feet and legs by providing a cushioned surface to stand on over prolonged periods of time. These mats are typically made of thick rubber, but some are also made of foam, leather, vinyl or even wood. In many cases, your employer will readily supply you with an anti-fatigue mat if you ask because they are proven to reduce the incidence of feet and lower leg problems. Thick anti-fatigue mats can be a minor hazard at the workplace if people trip over them, so always be aware of where your mat and those of your co-workers are located. Take a look around your workplace and see if there's any carpet you can stand on and still be able to do your job properly. Carpet (even the thin, cheap stuff) provides much more cushion than concrete and will help your feet and legs survive the long shifts at work. If there is no installed carpet at your workplace, ask your boss if you can bring a piece from home. Some businesses that sell carpet will give you a decent sized sample (big enough to stand on) for free. Make sure the underneath side of the carpet doesn't slide too readily on the floor, or else you're at high risk to slip and fall.
Summary: Stand in a different spot. Stand on an anti-fatigue mat. Stand carpeting.
