Any statistical work is generally made easier by having your data in a concise format. A simple table serves this purpose very well. To calculate the standard error of estimate, you will be using five different measurements or calculations. Therefore, creating a five-column table is helpful. Label the five columns as follows:  x{\displaystyle x} y{\displaystyle y} y′{\displaystyle y^{\prime }} y−y′{\displaystyle y-y^{\prime }} (y−y′)2{\displaystyle (y-y^{\prime })^{2}} Note that the table shown in the image above performs the opposite subtractions, y′−y{\displaystyle y^{\prime }-y}. The more standard order, however, is y−y′{\displaystyle y-y^{\prime }}. Because the values in the final column are squared, the negative is not problematic and will not change the outcome. Nevertheless, you should recognize that the more standard calculation is y−y′{\displaystyle y-y^{\prime }}. After collecting your data, you will have pairs of data values. For these statistical calculations, the independent variable is labeled x{\displaystyle x} and the dependent, or resulting, variable is y{\displaystyle y}. Enter these values into the first two columns of your data table.  The order of the data and the pairing is important for these calculations. You need to be careful to keep your paired data points together in order. For the sample calculations shown above, the data pairs are as follows:  (1,2) (2,4) (3,5) (4,4) (5,5) Using your data results, you will be able to calculate a regression line. This is also called a line of best fit or the least squares line. The calculation is tedious but can be done by hand. Alternatively, you can use a handheld graphing calculator or some online programs that will quickly calculate a best fit line using your data.  For this article, it is assumed that you will have the regression line equation available or that it has been predicted by some prior means. For the sample data set in the image above, the regression line is y′=0.6x+2.2{\displaystyle y^{\prime }=0.6x+2.2}. Using the equation of that line, you can calculate predicted y-values for each x-value in your study, or for other theoretical x-values that you did not measure. Using the equation of the regression line, calculate or “predict” values of y′{\displaystyle y^{\prime }} for each value of x. Insert the x-value into the equation, and find the result for y′{\displaystyle y^{\prime }} as follows:  y′=0.6x+2.2{\displaystyle y^{\prime }=0.6x+2.2} y′(1)=0.6(1)+2.2=2.8{\displaystyle y^{\prime }(1)=0.6(1)+2.2=2.8} y′(2)=0.6(2)+2.2=3.4{\displaystyle y^{\prime }(2)=0.6(2)+2.2=3.4} y′(3)=0.6(3)+2.2=4.0{\displaystyle y^{\prime }(3)=0.6(3)+2.2=4.0} y′(4)=0.6(4)+2.2=4.6{\displaystyle y^{\prime }(4)=0.6(4)+2.2=4.6} y′(5)=0.6(5)+2.2=5.2{\displaystyle y^{\prime }(5)=0.6(5)+2.2=5.2}

Summary: Create a five column data table. Enter the data values for your measured data. Calculate a regression line. Calculate predicted values from the regression line.


You want to be yourself around your crush, so don't center all the conversations around him and his interests — let him get to know you, too. Once you're talking regularly, try to look for shared interests to discuss. This way, you'll get to know each other better and bond through common traits.  For example, say you find out you both like Dancing With The Stars. Try asking him about the latest episodes after they air. For example, "Did you see Dancing With The Stars last night? It was so crazy." From there, you can look for broader topics of shared interests to discuss. For example, "Do you like dancing? I just love dancing and musicals." If a conversation is slowing down, ask a question. Asking someone about themselves will usually keep a conversation interesting. This will also give you a sense of whether you want to eventually ask your crush out. If you have a lot of shared interests and opinions, you're more likely to be compatible. You can ask questions like:  "What's your favorite movie?" "Do you have any hobbies?" "What's your favorite subjects in school?" "What's the coolest place you've ever visited?" "Who's your favorite television character?" When you really like someone, it can be very tempting to try and be the type of person you think they would be interested in dating. For instance, if the guy is really sporty but you couldn't care less about sports, you might be tempted to pretend you're also a big fan. Avoid this. Don't deny your own interests, hobbies, and friends out of fear of judgement or rejection. You can be polite about it ("Oh, I'm not really into football."), and use it as an opportunity to help him learn a little about you ("I actually really love going to see live music."). It can be hard to keep this in mind when you are crushing hard, but remember that someone who doesn't like you for who you really are ultimately isn't a good match for you. If you get his number, texting can be a great form of communication that can help you get to know him better. Try to text him once in awhile and see how he responds. This can help you see if he likes you as well. A guy who texts back eagerly is more likely to be interested.  Be yourself when you text. If he asks you questions, give honest answers. Use your own unique voice and sense of humor. Throw in an occasional emoji. Don't overdo it, but a few smiley faces now and then can come off as flirty. Allow him to initiate texting on occasion. You don't want to overwhelm him. As you're getting to know a guy, try to do some light flirting. This will convey your interest and allow you to get a sense of whether a guy likes you. If he flirts back, it's likely he's interested.  Smile. Smiling is contagious. Keeping eye-contact while smiling is key. This keeps the tension in the air flirty and fun. A smile to a guy gives him motivation to pursue you. Give him a brief smile and then look away. Make eye contact. This will convey interest. Try to introduce gentle touch. Lightly brush his arm when you're talking to him, for example. Some topics can tank a conversation, so they should be avoided. If you're trying to get to know a potential romantic interest, stay away from topics that may make him uncomfortable.  Avoid putting yourself down. You want to show that you like yourself and you're not insecure. Never say anything negative about his friends or family.
Summary: Discuss shared interests. Get to know him by asking questions. Be yourself. Text him regularly. Try to flirt some. Avoid certain topics.
