Choose someone who you've been in some uncomfortable situations with. These are most likely to be the times you've smiled inappropriately. Even if you're positive that you smile inappropriately, it's good to ask a friend. They might not have noticed, or the problem may not be as bad as you think. You can ask your friend to keep an eye out for your inappropriate smile in the future. Make sure they know to only alert you to it afterward, in private. Your friend might have insight into the kinds of situations that cause you to smile inappropriately. For example, they may notice a pattern such as you smiling when someone conveys bad news or when someone hurts themselves. You might already have an idea of what triggers your inappropriate smiling. Be as specific as possible in pinpointing what your personal triggers are. For example, instead of deciding that you smile when you feel uncomfortable, be more specific. Is it when you feel shy in front of an authority figure? Or when you feel put on the spot? Or when talking to someone you secretly find attractive? All of these situations might be uncomfortable, but the more specific you can be, the better. If you catch yourself smiling inappropriately, don't beat yourself up over it. Simply take note, and remember what the scenario was so you can practice changing your behavior. You may not want or be able to stop smiling at all uncomfortable moments. Pick one or two situations that you want to focus on while you practice not smiling. Your trigger may be one specific person or scenario. If this is the case, you may do best to avoid that person or scenario until you have become practiced at not smiling. You can choose the situation that is the hardest for you, or one that might be easier. It's up to you. You may want to pick a scenario you're in frequently, so you can use your new skills often.

Q: Simply put, what do you hope to gain from your survey? The questions you ask all need to point back to this essential idea. For example, say that you're an employer and you want to figure out whether your employees are happy. The survey questions you ask, either directly or indirectly, need to address the happiness of your workers. You could ask them directly, "On a scale of 1 to 10, how happy are you at work?" or you could formulate a more indirect question, like "True or False: I wake up every day feeling like my work has a purpose." After you've designed all your survey questions, it might be helpful to go through each question and ask yourself how each one is helping you accomplish the goal of the survey. Any question that doesn't give you essential information about your survey objective should be removed. If your goal is to figure out whether your employees are happy, you want an honest answer. In fact, with surveys, you always want honest answers. But it can be tough to get an honest answer if your employees feel like they could lose something respect, standing, etc. by being honest. Think about whether or not you need to tweak your survey in order to get honest results.With an employee happiness survey, for example, you might want to give respondents the option of completing it anonymously. Some options include telephone surveys, face-to-face interviews, surveys by mail, and Internet questionnaires. Each survey method has advantages and disadvantages, which should be weighed against the budget, available personnel and other considerations. In general, face-to-face interviews, although they are costly and time-consuming, deliver the most representative results and finest granularity in responses. On the other hand, online questionnaires sometimes come with significant biases, but they are the easiest and cheapest surveys to administer. If you're only going to rely on one form of survey, such as an online questionnaire, consider surveying more people to make up for possible biases. For the cleanest results, you might want to administer several different kinds of surveys. A survey that involves one or two respondents will tell you something about each one of the respondents, but it will not provide much accurate information about trends. In order to figure out how many people you should survey, you'll need two pieces of information: The size of your population. What population do you want to understand? If you want to understand happiness at your company, your population is the size of your company. If you want to study adoption of condom usage in Uganda, your population is the size of Uganda, or roughly 35 million. The certainty that your results are accurate. With survey accuracy, people talk about two ideas: margin of error and confidence interval. Margin of error is the degree of uncertainty you have in the results of your survey. Confidence interval is the degree of certainty you have that the survey samples the population accurately. Once you've answered the above questions what population am I targeting? and how accurate do I need to be in my results? you can start thinking about how many people you'll need to survey in order to get the desired results. In the table below, select your target population on the left, then select your margin of error to estimate how many surveys you'll need. As a general rule, the more surveys you give, the lower your margin of error will be.
A: Establish the goals for the survey. Spend some time thinking about how you can ensure the most honest answers. Decide on the best survey method to collect valuable information with the survey. Think about ensuring accuracy in your survey. Based on your target population and desired accuracy level, select your sample size.
