MTH 218 Help – Statistics II at University of Phoenix
We complete your hypothesis testing assignments, ANOVA/chi-square analyses, and research debrief memos. A/B guaranteed.
What Is MTH 218?
MTH 218 (Statistics II) is University of Phoenix’s second statistics course, following MTH 217. While Statistics I focused on descriptive statistics and basic inference, Statistics II dives into inferential testing: t-tests, chi-square tests, ANOVA, correlation, and regression. The course uses zyBooks and emphasizes applying these tests to real research articles through debrief memos.
Prerequisite: MTH 217 (Statistics I) or one college-level statistics course covering central tendency and data description. MTH 218 assumes you understand means, standard deviations, and basic hypothesis concepts.

MTH 218 Week-by-Week Breakdown
MTH 218 builds on MTH 217’s foundation with advanced inferential statistics. Each week introduces a new statistical test, culminating in a Signature Assignment on correlation analysis.
| Week | Topics | Key Assignments |
|---|---|---|
| Week 1 | Foundational Aspects of Hypothesis Testing: null/alternative hypotheses, significance levels, p-values, Type I/II errors | zyBooks, Discussion, Hypothesis Testing Presentation |
| Week 2 | Chi-Square Tests: testing independence, comparing proportions across categories, expected vs. observed frequencies | zyBooks, Discussion, Chi-Square Debrief Memo |
| Week 3 | t-Tests: independent samples, dependent samples, comparing two group means, effect size | zyBooks, Discussion, t-Test Data Analysis Presentation |
| Week 4 | ANOVA (Analysis of Variance): comparing 3+ group means, F-statistic, post-hoc tests | zyBooks, Discussion, ANOVA Data Analysis Presentation |
| Week 5 | Correlation & Regression: Pearson’s r, coefficient of determination, linear regression, prediction | zyBooks, Discussion, Signature Assignment: Correlation Analysis |
Heavy presentation load: Unlike many courses, MTH 218 requires PowerPoint presentations analyzing real data. You don’t just compute statistics—you present findings with speaker notes, interpret results, and make recommendations.
Statistical Tests You’ll Learn in MTH 218
MTH 218 teaches you when and how to use the major inferential statistical tests. Here’s what each test does:
Chi-Square Test (χ²)
Purpose: Test whether two categorical variables are independent. Example: Is there a relationship between gender and voting preference? Compares observed frequencies to expected frequencies if no relationship existed.
Independent Samples t-Test
Purpose: Compare means of two separate groups. Example: Do managers have higher performance ratings than individual contributors? Tests whether the difference is statistically significant or just random variation.
Dependent Samples t-Test (Paired)
Purpose: Compare means from the same group at two different times. Example: Did employees’ satisfaction scores improve after a training program? Before vs. after measurements on the same subjects.
One-Way ANOVA
Purpose: Compare means of three or more groups. Example: Which shift (day, night, weekend) has the highest product sales? The F-statistic tells you if at least one group differs; post-hoc tests tell you which ones.
Correlation (Pearson’s r)
Purpose: Measure the strength and direction of a linear relationship between two continuous variables. Example: Is there a relationship between employee performance ratings and sick days? Values range from -1 to +1.
Linear Regression
Purpose: Predict one variable from another and quantify the relationship. Example: Can we predict sales based on advertising spend? Gives you an equation (y = mx + b) and tells you how much variance is explained.
Why Students Struggle with MTH 218
MTH 218 is where many students hit a wall. Here’s why:
Knowing Which Test to Use
The hardest part isn’t running the test—it’s knowing which test fits your research question. Chi-square vs. t-test vs. ANOVA vs. correlation? Each has specific requirements (variable types, number of groups, independence), and choosing wrong invalidates your analysis.
Interpreting p-Values and Results
Getting a number is easy. Understanding what it means is hard. What does p = 0.03 actually tell you? What’s the difference between statistical significance and practical significance? MTH 218 expects you to explain results in plain English—not just report them.
Presentations Every Week
This isn’t a “do the math and submit” course. Weeks 1, 3, and 4 require PowerPoint presentations with speaker notes analyzing real datasets. Week 2 and Week 5 require professional memos. You’re presenting statistical findings to a business audience.
MTH 217 Foundation Required
If you struggled in MTH 217 or scraped by without truly understanding hypothesis testing fundamentals, MTH 218 will expose those gaps. Everything builds on null/alternative hypotheses, p-values, and sampling distributions from Statistics I.
💡 The Core Challenge
MTH 218 isn’t about memorizing formulas—software handles the calculations. It’s about understanding what questions to ask, which tools to use, and how to interpret answers. That conceptual leap is where most students struggle, especially in a 5-week compressed format.

MTH 218 FAQ
What’s the difference between MTH 217 and MTH 218?
MTH 217 (Statistics I) covers descriptive statistics, basic probability, and introduces hypothesis testing. MTH 218 (Statistics II) goes deeper into inferential statistics: chi-square tests, t-tests, ANOVA, and correlation/regression. Think of 217 as “understanding data” and 218 as “testing claims about data.”
Is MTH 218 harder than MTH 217?
Yes, for most students. MTH 218 requires you to apply hypothesis testing to multiple different scenarios and choose the right test for each situation. The concepts are more abstract, and the presentations/memos require higher-level interpretation skills.
Do I need to know Excel or statistical software?
The course introduces using Excel and statistical software for calculations. You don’t need prior expertise—zyBooks walks you through it. However, you will need to run analyses and interpret output for your presentations and memos.
What are the Research Article Debrief Memos?
Professional business memos where you read a published research article, identify the statistical methods used (chi-square, correlation, etc.), explain what the researchers found, and assess the validity of their conclusions. Same format as MTH 217’s memos but with more advanced statistical methods.
Can I bundle MTH 217 and MTH 218?
Yes—we recommend it. Most students take both statistics courses consecutively, and bundling ensures continuity. Ask about pricing when you contact us.
How quickly can you start?
Most students begin within 24 hours. Send your syllabus and current standing—we respond quickly. With weekly presentations due, timing matters in MTH 218.
