PSYC 354 SPSS H OMEWORK : O NE -S AMPLE T T EST AND C UMULATIVE Q UESTIONS T EMPLATE Problem Sets 1 and 2: The One-sample t test Problem Set 1: Research Scenario: An industrial-organizational psychologist wants to measure the effect of the Covid pandemic on the life satisfaction of nurses actively working during the pandemic. She administers the Satisfaction with Life Scale ( Diener et al., 1985 ) to thirteen nurses during the pandemic. The population mean for nurses is m = 23.6. Using the sample data in the table below, set up your data file in SPSS and conduct a one-sample t test to determine whether this sample has a lower SLS score than the general population of nurses. Create a histogram to display the distribution of the sample’s SLS scores. Remember to put your initials within any and all variable names. SLS Scores 24 24 19 20 26 16 17 16 25 13 29 12 18 1. Paste SPSS output of the t test here: (7 pts) 2. Write an APA-style Results section based on your analysis. Include an APA-style Results section heading. Include your histogram as an APA-style figure, with figure number and title. Figure formatting and a Results section template are included in the “Results Sections for the One-Sample t Test in APA Style” presentation this week.

PSYC 354 Problem Set 2: Research Scenario: A neuropsychologist who works with clients over 60 years of age gives 16 clients a questionnaire that measures the severity of dementia symptoms. On this measure, scores range from 1-20. Lower scores indicate a lack of, or low severity of, dementia symptoms; while higher scores indicate more severe dementia symptoms. The mean in the general population of healthy adults is 5. Using the data in the table below, set up your data file in SPSS and conduct a one-sample t test to determine whether this sample has higher scores than the general population. Create a histogram to display the distribution of the sample’s scores. Remember to put your initials within any and all variable names. 3. Paste SPSS output of the t test here: (7 pts) 4. Write an APA-style Results section based on your analysis. Include an APA-style Results section heading. Include your histogram as an APA-style figure, with figure number and title. Figure formatting and a Results section template are included in the “Results Sections for the One-Sample t Test in APA Style” presentation this week.

PSYC 354 1. Using the data in the table above, set up a data file in SPSS and create a bar chart that shows the percentages for each religion. Paste the bar chart here: (5 pts) 2. What level of measurement (nominal/ordinal/scale) is the variable “Percent of US Population”, and why? (5 pts) 3. What level of measurement (nominal/ordinal/scale) is the variable “Religion”, and why? (5 pts) Problem Set 5: The Wechsler Intelligence Scale for Children, version 5 (WISC-V) produces a score called the Full-scale IQ (FSIQ) (Wechsler, 2014). The population mean for children considered “gifted” is m = 136. A school psychologist administers the WISC-V to 18 fourth- grade students being considered for advanced classes. The results appear in the table below. They are entered as 2 columns here to save space (i.e., enter them in 1 column in your SPSS file). Remember to put your initials within any and all variable names.

PSYC 354 1. Using the data in the table above, set up a data file in SPSS and create a frequency table to show the frequency of each score on the WISC-V. Paste the frequency table here: (5 pts) 2. What percentage of children have a WISC-V score of 129? (5 pts) 3. What is the frequency of children who have a WISC-V score between 110 and 130? (5 pts) 4. Using the same data, create a histogram in SPSS to show the distribution of the WISC-V scores. Paste the histogram here: (5 pts) 5. If the school psychologist uses the given population mean as a cutoff, how many children would be admitted to advanced classes based solely on their WISC-V score? (5 pts) END OF ASSIGNMENT Page 5 of 5
