Business Statistics Discussion Post

I’m trying to learn for my Statistics class and I’m stuck. Can you help?

Relationship of Height and Weight

Your initial post should be 75-150 words in length.

  • What does it mean when we say that there is a relationship between two variables?
  • What kinds of relationships can there be between two variables?
  • Give an example of two variables that are related. For example, my daughter has an hourly salary. Her paycheck amount is related to how many hours she worked.
  • Give an example of two variables that are NOT related.
  • Select the following Table: Height and Weight data set. Follow the steps in the weekly video or on pages 584-585 of the textbook for performing a regression analysis using Excel to analyze the Height and Weight Data set (assume height is the input variable x and weight is the output variable y). Once you have performed the analysis in Excel, state the correct simple linear regression equation and use the regression equation to predict the weight (in pounds) of a person who is 65 inches tall and the weight (in pounds) of a person who is 100 inches tall.
  • Why might the regression equation you have found NOT be a good prediction of the weight of someone who is 100 inches tall? How does this lesson apply to the workplace?
