**Math 163- Basic Statistics**

**Math 163- Basic Statistics** (3 credits)

**Description:** Organizing data: displaying distributions, measures of center, measures of spread, scatterplots, correlation, regression, and their interpretation. Design of experiments: simple random samples and their sampling distribution, models from probability, normal distributions, and normal approximations. Statistical inference: confidence intervals and hypothesis testing, t procedures and chi-square tests. Not intended for those who plan further studies in statistics.

**Placement Level:** ALEKS PPL score of 60-100% , SAT I MSS 640-800, ACT MATH 26-36, or U of A Math 112 required for placement into this course. Test scores expire after one year. SAT/ACT placement is generally for first year students only.

**If my scores are lower than the Placement Level:** Math 100, then Math 112, then Math 163. Students who have credit for Math 120R, 122B or 125 also qualify to enroll in Math 163.

**Comments:** Not a prerequisite for any math or lab science (CHEM, MBC, PHYS) courses. Students in nursing, nutritional sciences should take this instead of Math 263. Recommended as a second semester course.
