Assignment 7
Descriptive stats II
A. Suzy Q, a student in a political science course, conducted a small survey to find out how BSU students feel about a couple of current political issues. In addition to several important questions about demographic information, students were asked the following question:
1. Please indicate whether you agree or disagree with the following statements:
Congress should pass new legislation to regulate the behavior of corporate executives.

a. Create the frequency distribution table manually (without using SPSS) for Respondent's sex. (You can hand write and take a picture, if you like. Copy the picture and paste it in Word.)
Calculate the measure of central tendency and variability. Calalculate the mode for the measure of central tendency, since it is a nominal variable. Calculate the range for the measure of variability. Make sure that you are not including a missing case in counting the number of cases. So, if there are 16 cases, N=15, when there is a missing case. For variability, calculate the range for a nominal or an ordinal variable. Calculate the standard deviation for an interval variable. Use N1 instead of N in calcualting the standard deviation.)
Hint for the calculatkon of the median
1) Low 55% 2) High 45%
The median case belongs to the category Low, since the 50th percentile case belongs to the Low category. (Use the valid % column.)
c. Open a new SPSS data file and complete the following:
1) Create the dataset. Hint: Go to the "Variable View" page and create the variables SEX, AGE, and Question1 by typing these names in the column, NAME. Label the categories. For example, you can type 1 for males and 2 for females in the "values" column. Go to the "Data View" page, type 1 for males and 2 for females. Leave the missing cases blank. (Do not type "0", unless you specify it as a missing value in the "Missing" column. If you type 0 in the Age variable, for exaple, SPSS will think that the respondent is a baby!)
2) Run the frequency distribution table for the variable, SEX (SPSS: Analyze, Descriptive, Freq.) At the same time, find the values for central tendency and variability (i.e. dispersion). (Click on the Statistics option after following Analyze, Descriptive, Freq). For central tendency, choose Mode, since it is a nominal variable. For variability, choose Range.)
Copy and paste the output tables to a Word file.

If you make any mistakes, the instructor will let you know how to improve your assignment. You can redo your assignment and show the instructor the improved version. Repeat the process until everything is correctly done. Save your file and deposit the final version to Blackboard. Visit www.bsu.edu/blackboard and go to POLS210. Find Assignment 7 and double click and upload your file as a WORD file. (You can include a picture in a Word file, but you cannot submit a picture by itself.) You will receive 100%. Blackboard allows you to deposit only once. If you did not complete the assignment during the lab hours, you must deposit your assignment to Blackboard by 5pm next day. The instructor will grade your assignment. (You will not be able to redo the assignment, even though your score is lower than 100%.)
