SPSS Statistics

Details:

The purpose of this assignment is to apply data distributions to discrete and continuous data and justify the selection of the distributions.

For this assignment, you will use the “Random Variables” dataset. You will use SPSS to analyze the dataset and address the questions presented. Findings should be presented in a Word document along with the SPSS outputs.

The dataset provided consists of the following random variables:

1. BMI: The body mass index of a random set of people.
2. Distance: The distance (in feet) that a baseball player hit the ball.
3. Height: The height of males (in mm).
4. Income: The income (in dollars) of people in a large company.
5. Pass: The outcome when taking an exam (1=Pass; 0=Fail).
6. Wait Time: The time (in minutes) that it takes when waiting for the train.

Answer each question below. Use SPSS as needed, and include the software outputs as part of the Word document you submit. Also attach the SPSS Statistics output file.

1. What is a Q-Q plot?
2. Given a set of realized values of a random variable, how can a Q-Q plot be used to assess the distribution of the random variable?
3. Using histograms and Q-Q plots (except for binomial), match each random variable to one of the following distributions: Binomial (with N=1, P=0.7), Chi-square (with d.f.=20), Exponential, Lognormal, Normal, and Uniform.
