Problem: Article: If you're traveling alone, you're often an easier target than with a group of friends or relatives.  Groups of teens often are more inclined to act out when in a group.  Their group is their security, and they may want to show-off in front of their peers.  Find ways to travel more often with someone you trust, particularly at night or in areas where you know there's been trouble. While this may not come easily, it's important to see that increasing your self-esteem will allow you to act and behavior more assertively.  Try to dress and do things that don't draw attention to yourself in a way that may lead to ridicule.  Bullies often find ways to make others feel more vulnerable, so blending in may be helpful. By participating in a class, the act of taking action will lead to greater self-esteem, and in turn a greater sense of strength.  Most martial artists will tell you that the first day you start a martial arts class is ironically the last time you ever fight. With the use of discipline as taught in martial arts, the ability to walk on past a group of bullying teens will seem much less intimidating. If there's a group of teens who aren't actively provoking you, but just acting a little suspicious, try breaking the ice.  Consider having a brief but positive conversation with them, rather than assuming it will be negative.  Sometimes loitering teens just want to have a purpose, particularly if they're hanging out in the same spot regularly.  Consider engaging them in a useful way, like being a look-out for other suspicious activity. Or just simply introduce yourself and make small talk. See if being "neighborly" reduces the negativity.
Summary: Travel in groups of two or more. Dress and act with confidence. Learn self-defense such as martial arts, or take a self-defense class. Try having a positive interaction with them.

INPUT ARTICLE: Article: Show that you mean business by arriving five to ten minutes early for any meeting or appointment you might have.  This shows that you respect your time and the time of others. This applies to professional settings.  It is typically okay to be a few minutes late to parties and other social events. Stay up on the current events in your city, state, country and the world.  Don’t just know about the latest pop culture, know about the politics that are affecting you.  This will give you serious topics to discuss with others. Download news apps to your phone and take fifteen minutes daily to read articles every morning.  You can even sign up for news alerts. Should you be assigned a task at work or school, work diligently on it.  Do your research so you can do it to the best of you ability.  If there is a presentation portion, practice beforehand until you have mastered it.  This will show that you take your work seriously. For instance, if you have a presentation coming up, prepare a powerpoint.  Use a simplistic format and include visuals or charts.  Check for typos and practice presenting in the mirror. Take care of your appearance by showering and keeping your hair and clothes presentable. This will keep you looking sharp, neat and clean. You don't have to look ready for a board meeting (unless you're actually going to a board meeting), but you should always look nice.  Iron your clothes the night before so you don’t have to rush in the mornings. Use your clothes to tell people what you want them to think about you. If you want to be taken seriously, don't do things that make people think less of you. Avoid public intoxication, drugs, crime, and other poor decisions.  Instead, involve yourself in positive activities like volunteering. Be mindful of what you post on social media, too.  Avoid posts that glorify drugs, violence or other negative behaviors. If you tell someone that you will do something, you should follow through on that. If they see you as someone that just makes empty promises, they will be very unlikely to take you seriously. Perhaps you promised a coworker that you would pick them up the following morning for work.  Be sure to set a reminder on your phone and wake up early so you can keep the promise. If you are lying often, you can’t really expect people to believe you. They aren't going to trust you to tell them the right information. Always be truthful with others, even when it’s difficult.  They will begin to take you seriously if they know you will be honest with them. People value honesty and genuineness in others. For example, if you don't know something, say, "I'm not familiar with that, but I'll look it up." If someone is being rude to others or suggest something that is wrong, speak up for what you believe.  Do so in a respectful and kind manner.  This will show to others that you have integrity and that you’re willing to fight for what’s right. For instance, your boss might suggest paying the new female coworker less than the male staff because of her gender.  Let him know that this is not okay and that she deserves equal pay to do equal work.

SUMMARY: Arrive early. Read the news. Prepare for your assignments or projects. Dress for success. Set up a good reputation. Follow through on your promises. Tell the truth. Speak up when you disagree.

In one sentence, describe what the following article is about: Take all of your calculated returns and add them together. Then, divide by the number of returns you are using, n, to find the mean return. This represents the average return over the time period you are measuring. Specifically, the mean, m, is calculated as follows: m =(R1+R2+...Rn)/(n). For example, imagine that you had 5 periods that had calculated returns of 0.2, -0.1, -0.3, 0.4, and 0.1. You would add these together to get 0.3 then divide by the number of periods, n, which is 5. Therefore, your mean, m, would be 0.3/5, or 0.06. For every return, Rn, a deviation, Dn, from the mean return, m, can be found. The equation for finding Dn can be expressed simply as Dn=Rn-m. Complete this calculation for all returns within the range you are measuring.  Using the previous example, you would subtract your mean, 0.06, from each of the returns to get a deviation for each. These would be: D1=0.2-0.06, or 0.14 D2=-0.1-0.06, or -0.16 D3=-0.3-0.06, or -0.36 D4=0.4-0.06, or 0.34 D5=0.1-0.06, or 0.04 Your next step is to find the mean variance of the returns by summing the squared individual deviations from the mean of the returns. The equation for finding the variance, S, can be expressed as: S=(D1^2+D2^2+...Dn^2)/(n-1). Again, sum the squares of the deviations, Dn, and divide by the total number of variances minus 1, n-1, to get your mean variance.  First, square your deviations from the last step. These would be, in order: 0.0196, 0.0256, 0.1296, 0.1156, 0.0016. Sum these numbers to get 0.292. Then, divide by n-1, which is 4, to get 0.073. So, S=0.073 in the example. The volatility is calculated as the square root of the variance, S. This can be calculated as V=sqrt(S). This "square root" measures the deviation of a set of returns (perhaps daily, weekly or monthly returns) from their mean. It is also called the Root Mean Square, or RMS, of the deviations from the mean return. It is also called the standard deviation of the returns.  In the example, this would just be the square root of S, which is 0.073. So, V=0.270. This number has been rounded to three decimal places. You may choose to keep more decimals to be more accurate.  A stock whose price varies wildly (meaning a wide variation in returns) will have a large volatility compared to a stock whose returns have a small variation. By way of comparison, for money in a bank account with a fixed interest rate, every return equals the mean (i.e., there's no deviation) and the volatility is 0.
Summary:
Find the mean return. Calculate the deviations from the mean. Find the variance. Calculate the volatility.
