Project #21863 - Quantitative Methods HW

1.

x = {8,3,5,5,6,2}

 

Using the data above:

  1. Demonstrate that subtracting a constant from every score reduces all measures of central tendency by that amount
  2. Add a 7th score to the sample to make the sample mean equal to 6.0. How is this exercise related to the concept of degrees of freedom described in the book?

 

2.

x = {4,6,3,8,2}

 

Using the sample data above:

  1. Multiply each of the scores above by a constant. What happens to the (sample) standard deviation?
  2. Add a constant to each of original scores above. What happens to the standard deviation now?

 

3.

x = {5,8,3,8,6,9,9,7}

 

Using what you learned in problem 2, transform the sample of scores above to form a new sample with a standard deviation of 1.0.
