How to Do a Simple Regression using a Casio Calculator

id="mod_20738033">Statistics and Simple Regression Statistics may be something that a lot of students dread (and even those who are now working). All those complicated computations simply make you go crazy! Take for example regression analysis. It requires several computations to arrive with values for the intercept, slope and etc. And doing it manually, which is something needed in class, can be a real source of headache. One mistake would make everything go wrong. So, is there a way for us to verify our answers and even aid us in our calculations? Well, fortunately there is! You just need a calculator that has this special function. In this article, we will know how to utilize that function using a CASIO calculator. X Y 240 3.6 236 3.4 290 4.3 500 8.1 630 10.2 444 7.1 Learning by Doing To help you out in learning how to do it, let's use the table on the right as an example. We will be conducting a simple regression using these values. <u>Okay, so now, grab your calculator and let's get going!</u> Click thumbnail to view full-sizeStep 1: Instruct your calculator that you will be conducting a statistical analysisStep 2: Specify that you will be doing a simple regression analysisStep 3: Input the values for the dependent variable and the independent variableStep 4: Initiate the regression analysisStep 5: Calculate for the intercept, slope and R Simple Regression Using Casio Calculator <b>So, here are the 6 basic steps on how you can conduct a simple regression in your calculator:</b> First, press on the MODE button to make 8 mode options appear in your display. Then, among those options, press the number that corresponds to STAT. Again, there will be another set of 8 options to choose from. Press the number that corresponds to A+BX since this is the function for conducting a simple linear regression. <strong>Input all the data (see the previous table), and press AC afterwards.</strong> Press the <a href="http://edublogs.org/?s=SHIFT%20button">SHIFT button</a> followed by the STAT button (this is usually the button corresponding to 1). Then, press on the number indicating REG (which is typically 7). Okay, we are getting nearer! Now, to solve for the intercept (represented by "A"), press 1; for the slope (represented by "B"), press 2; and for R (represented by "r") , press 3 followed by the "=" sign. Again, numbers to press may vary depending upon the model of your calculator. <b>Repeat Step 5 for the other requirements (e.g. slope, R, etc)</b> To check if you were able to do it right, here are the answers you should be getting (rounded off in <a href='http://vtr.org.vn/cong-ty-du-lich-ky-nghi-dong-duong-thuong-hieu-viet.html'>tour bắc kinh từ hà nội</a> 5 decimal places): <b>a (intercept) = -0.63035</b> <b>b (coefficient) = 0.01730</b> <b>R = 0.99961</b> If you were able to get them all, then <a href="http://Www.Bbc.Co.uk/search/?q=congratulations">congratulations</a>. If not, you may want to check the step-by-step procedures, and make sure you are not missing anything. <a href="https://www.kynghidongduong.vn/blog/bac-kinh-thanh-pho-hien-dai-va-co-kinh.html">tour bắc kinh giá rẻ</a> Check also if you were able to input the data correctly, since it's usually the common error. <b>Important Note</b> It is essential to know that not all CASIO scientific calculators have this function. Also, the steps enumerated above may not be applicable to other brand of calculators. If in case you'll ask, SHARP also have calculators that can do simple regression analysis. <b>Get your own scientific calculator that can perform regression!</b> (CASIO) Scientific Calculator (FX-991ESPLUS)This is the calculator model that I am currently using.
