Select one of your variables (the one you would like to predict) as the dependent variable, \"y\" and the other variable as the independent variable,\" x\". You can use Excel. Stat crunch or a 1183.984 calculator to perform a linear regression analysis. If you are using a computer program. such as Excel or Stat Crunch. you may want to copys'paste your regression table results into your report. If you are using Excel. there is an option to display the \"trend line\" with the equation and Rsq. value directly on the scatterplot. Your project should be submitted in a semi-professional looking report. preferably typed in Word. Include the following in your report. 1. Introduction: Briey describe your sample and your two quantitative variables, including their units of measurement. State that the purpose of your analysis is to use linear regression to predict "y\" (ll in what your "y variable" is) for any given value of \"x" (ll in What your x variable is). 2. Insert a scatter plot. Make sure your \"x" (independent) variable is on the \"x- axis" and the \"y\" (dependent) variable is on the 'y-axis". 3. Find & practically interpret the correlation coefficient (r) 4. Find & practically interpret the coefcient of determination (R) 5. Find the equation on of the leastsquares line (be specic ) 6. Find & practically interpret the slope (be specic ) 7. Find & interpret the yintereept if an interpretation is possible. If it's not possible. just report the yintercept and explain why it cannot be interpreted practically 8. Brief conclusion or discussion of the results (e.g. assumptions, potential problems, are the results what you expected? use the model to make a prediction, etc.) Note: Regression line. line of best t. and least-squares line all refers to the same thing. Suggestions: Take a moment to think about which variable you would like to make your dependent (y) variable and which variable you would like to make your independent (x) variable. The y variable is the one you would like to predict based on it. Make a note of which one you selected for y and which for x. then when going through your interpretations, don't mix them up. There is a tutorial on how to create scatter plots and nd the least-squares regression line in Stat Crunch and Excel. While the tutorial will walk you through how to get your results, it does not Show you how to do the interpretations. I would recommend re-watching the videos on regression (or viewing the example attached). In Stat Crunch. there is an option to \"group by" when doing a regression analysis. Do NOT use this option
