SPSS Lab # 2 INSTRUCTIONS: Enter the data for the two datasets into SPSS. Be sure to enter value labels for the qualitative variables. Your responses MUST BE TYPED and you must follow all other instructions or I will deduct up to 4 points from your final grade for the assignment. Be sure to hand in your typed responses to the questions below as well as your SPSS output. Note that for all hypotheses, use ? = .05. Remember that in SPSS, you will compare the p-value (indicated as sig. in your SPSS output) to ? to determine whether or not to reject the null hypothesis. Each analysis is worth 5 points (5 points at 4 analyses = 20 points total). Each question within each analysis is worth 1 point. 1. For each research question, a. Determine the appropriate statistical test b. Complete the following steps of hypothesis testing i. Formulate hypothesis (write out in symbolic form) ii. Run the relevant statistics iii. Decide whether to reject or accept the null hypothesis iv. Write a sentence reporting your findings DATASET 1: You are asked to analyze the data for a small business owner who has conducted a study to look at factors that may affect work performance (i.e., typing accuracy) and job satisfaction among a group of 15 administrative assistants. Typing accuracy is assessed using the number of words typed correctly in 60 seconds. Employee satisfaction is assessed using a 0 to 100 scale where 0 = not at all satisfied and 100 = completely satisfied with their job. He is particularly interested in looking at the effects of a flexhours plan on his outcome measures. In the flex-hours plan, employees are allowed to choose when they work as long as the total hours worked is at least 40 in a 7 day period. The employer wants to answer the research questions, below. Note that each research question will need to be tested using a different statistical test. 1. Does implementing the flex-hours plan improve typing accuracy. In the past, administrative assistants in the company typed an average of 55 words correctly in a minute. 2. Who types words more accurately, males or females? 3. What is the impact of the flex-hours plan on employee satisfaction? The employer administers a baseline measure which assesses gender and employee satisfaction. He implements the flex-hours plan and after 30 days, assesses employee satisfaction again. He also has the administrative assistants complete the typing accuracy test. He has collected the following data (the SPSS variable names for each variable are in parentheses): Gender (Gender) Male = 1; Female = 2 Male Male Female Female Female Male Female Female Female Female Male Female Male Male Female Pre-Satisfaction Measure (PreSat) 45 80 68 72 30 50 44 59 47 55 75 25 40 42 35 Post-Satisfaction Measure (PostSat) 55 80 72 70 50 45 55 58 80 85 90 55 53 50 45 Typing Accuracy (Perform) 45 50 65 70 64 70 63 80 78 50 48 81 57 50 75 DATASET #2 You are a school psychologist who is interested in testing three different behavior management approaches as compared to the standard approach to behavior management for children with emotional and behavioral disorders in a regular education classroom. The three approaches are as follows: (1) Standard approach in which the teacher deals with behavior problems in the way s/he typically does (i.e., talking to the student for one to three offenses and sending the student to the principal’s office for any more than three offenses); (2) a Punishment approach in which the teacher ignores problematic behavior (negative punishment) unless the student is harming him/herself or another student; in the latter instance, the student is sent to the principal’s office for detention; a positive punishment approach; and (3) A Punishment and Reinforcement approach in which the teacher puts the student in time out when problematic behavior is observed (negative punishment) and rewards the student when s/he is engaging in prosocial behavior. Three different teachers are assigned to use one of the three approaches. You gather observations of 8 different children in each classroom (N = 24) and record the number of problematic behaviors for each student during a 30-minute observation period. The data are on the next page. You test the following hypotheses: 1. The number of problematic behaviors will differ depending on whether the student is in the standard, punishment, or punishment and reinforcement classroom. 2. The Punishment and Reinforcement approach will have fewer instances of problematic behavior than the other two treatments; the Punishment approach is expected to have fewer instances of problematic behavior than the Standard approach.
