If no brackets used then division must be made before addition and subtraction, i.e.
12 + 8/7 - 2 = 12 + 1and1/7 - 2 = 11 and 1/7 = 11.(142857).

Scatter Plot, Linear Regression and R Value
Topic 1: Scatter Plot, Linear Regression and R ValueView Full Description Hi Everyone,Open excelIn one column enter 8 heights for 10 year old boys (inches) and in the second column enter 8 weights for 10 year old boys (pounds). Ten year old boys height ranges from 42 inches to 62 inches while the weight ranges from 60 to 90 pounds. You can make these up as long as they are reasonable if you do not have access to any data. We want to see if there is a correlation.Move your mouse to put a box around the numbers.From the insert menu select scatter or the chart that says scatter and then select the chart at the top left on the dropdownClick on one of the pointsSelect Add TrendlineThe default radio button is linear, keep it checkedCheck display equation on chart and click on the display r-squared valueThe equation is your least squares lineOn the least squares line the slope is in front of the x value. Also, you can look at the slope of the scatter plot to see if the slope is positive. This will let you know whether to make the r value positive or negative when you take the square root of r^2.If the r^2 value is say .0382 then you will click on an excel cell and type=.0382^.5Note the ^ key is above the 6 keyThis will be your r value and you will make it negative if your slope is negative otherwise leave it positive.If you have a different version of excel then you may want to search to see how to form a trendline. These instructions work with Office 365 and Office 2010.Then follow these instructions:Attach your scatter plot if possible. What did you get for your regression line? What was your r value? What did this tell you?What would be a scenario where you might need to use this application?Be sure to comment on at least 2 classmates.Instructions: Your initial post should be at least 250 words. Please respond to at least 2 other students. Responses should be a minimum of 100 words and include direct questions.
