5. Describe one limitation of using regression equations to make predictions about outcomes. Include an example to illustrate this.
Homework Answers
One of the limitations of using regression equations to make predictions about outcomes is:
Linear regressions are sensitive to outliers.
E.g. if most of your data lives in the range (100,150) on the x-axis, but you have one or two points out at x= 500, this could significantly swing your regression results.
Similarly, if you build your regression on the range x in (100,150), and then try to use that model to predict a y-value for x = 500, this is pretty significant extrapolation and is not necessarily going to be accurate.

Researchers have collected data that shows a relationship between eating french fries and the risk of premature death. (See the Washington Post article ) Is it safe to assume, on the basis of these data, that eating french fries leads to premature death?

Using an example of a contemporary information technology, describe each of Masuda’s predictions for our information society: (a) Foster voluntary communities; (b) Break down hierarchies; (c) Empower citizen movements; (d) Spur individual knowledge creation. (One technology might explain all 4, or you can use different technologies for each prediction.)
How can force and energy models be used to describe or make predictions about angular motion?...
How can force and energy models be used to describe or make predictions about angular motion? What are the rotational analogues for velocity, mass, momentum, force, and energy? How are they related to the linear version of these quantities? In what ways can linear and angular dynamics be analyzed separately and in what ways are they interconnected.

Confidence intervals are a way to make predictions about entire populations using a random sample. Suppose you do not know the value for a certain population mean, such as the average miles per gallon for some new brand of car. You don’t have the data for every single car of this new brand, so you can’t calculate the population mean. However, you can try to estimate it. What value is the point estimate for the population mean? Describe, in your...

Make up an example of a one-tailed test. Draw a curve and shade in the region you are interested in. Make up an example of a two-tailed test. Draw a curve and shade in the region you are interested in. List the four possible outcomes for any hypothesis test. If you are concerned about the Type I Error, how should a proposed hypothesis test be modified? Name three ways power can be enhanced. Using a group of four subjects, an...
