Course grades in PSYC 421 use Liberty's point scale: an A is 900 to 1010 points of the course total. Missing the length or source minimum usually costs points on several rows at once, which is why the checklist below starts with them.

The PSYC 421 Week 2 method, step by step
Set up the data before the write-up
Work through the SPSS Assignment Part 1 calculations or software steps first and save the output. The written part interprets those numbers, so they have to be right before you explain them.
Show the method
Say which method, formula or test you used and why it fits the question. Graders want to see that the choice was deliberate.
Report the results plainly
Report each result with its value and what it measures. Tables and figures help when they are labeled and referred to in the text.
Interpret in the context of the question
Translate the numbers into a conclusion about the question. Say what decision they support and how confident you can be.
Name the limits
State what the analysis cannot tell you: assumptions, data limits, or what would change the answer.
Submit the files the guide asks for
Submit every file requested and check that formulas, output and the write-up agree (Not set in the guide; follow the assignment instructions).
Run Frequencies for categorical variables and Descriptives for scale variables, build a single table in APA style, use bar charts for categories and a histogram for age, then summarize who the sample includes.
A structure for PSYC 421 Week 2 SPSS Assignment Part 1
Word targets are planning numbers for about 1,000 words of body text, set by the length in the guide; the rubric decides where to spend more.
| Section | What it must do | Target |
|---|---|---|
| Descriptive statistics | Right statistic for each variable. | ~400 words |
| Graphs | Appropriate and labeled. | ~300 words |
| Summary | Clear description of the sample. | ~300 words |
A topic angle that works
Choose statistics by measurement level: frequencies and percentages for categorical variables such as gender and ethnicity, and mean and standard deviation for scale variables such as age.
Model paragraph with notes
An original paragraph written by our desk to show the register that earns full rubric credit. It is study material: learn the moves, then write your own.
The normative sample included 412 adults, 54% female, with a mean age of 38.6 years (SD = 12.4). Most participants identified as White (61%), followed by Hispanic (17%) and Black (14%). Compared with U.S. census figures, adults over 65 were underrepresented, which limits the norms' use with older clients.
