Required Text: Understandable Statistics: Concepts and Methods, WITH Web Assign by Brase & Brase 11th ed.
Prerequisite:
Three years of high school mathematics and an appropriate score on the
Mathematics Placement Test or completion of MATH 1100 or MATH 1110 with a grade
of B or better.
Description: A nontheoretical introduction to statistics with an emphasis on applications in a variety of disciplines. Topics include measures of central tendency, position and dispersion; basic probability; hypothesis testing; estimation; analysis of variance; linear correlation and regression; nonparametric statistics. Prerequisite: Three years of high school mathematics (including two years of algebra) and an appropriate score on the Mathematics Placement Test, or completion of MATH 1170 or higher.
Goals and objectives of the course:
Upon completion of this course, the student will be prepared to interpret and use statistics that they encounter both in connection with their discipline and in everyday life. The student will also be able to conduct basic statistical inference.
Grades: Grades for this course will be based upon homework, quizzes, tests, and a comprehensive final exam; some of the quizzes may be unannounced. Items for both will come from the assigned homework. The following grading scale will be used to determine grades:
A | 90 – 100 % |
B | 80 – 89 % |
C | 70 – 79 % |
D | 60 – 69 % |
F | Below 60% |
Make-ups are not allowed for missed quizzes, instead I will allow you to drop your lowest score. All tests will count toward your final grade. The instructor reserves the right to adjust the grading scale if necessary.
Working through the assigned problems is essential to learning mathematics. Showing your work is the only way to receive partial credit; hence it is very important on quizzes and exams.

The Normal distribution -- Normalcdf(l,u) on TI-84 | |
Normal distribution continued -- using standard scores (z-scores) | |
Oct 13 | Normal distributions as graphs, using the Normalcdf(l, u,, ) function where l = lower, u = upper,= mean, = standard deviation AND the invNormal(p,, ) where p = percentage,= mean, and = standard deviation |

Looking at Confidence Intervals -- 95% or 99% or ... Guess the weight of a 747. Guess an interval into which the weight of a 747 would fall. | |
Drawing samples and calculating confidence intervals, Z-interval or the t-interval. To Z or not to Z, that is the question! |

Alternate methods for finding confidence intervals (Zinterval and TInterval on TI calculator) AND it's my birthday -- sure hope someone brings treats!! | |
Using proportions to create a confidence interval. Quiz - Comparing different confidence intervals | |
Null hypothesis, alternative hypothesis, Type I error (falsely rejecting the null), and Type II error (failure to reject the null). | |
