MAT 101M: Mathematics for the 21st Century

Fall 2018

Exam 3 information

1. Notes and materials

You are permitted one letter-size handwritten notes sheet (both sides) for use as a reference during the exam.

The following reference tables, if needed, will be provided to you. It might be provided exactly as in the textbook, abbreviated, or include similar, but not the same, information.

• Table 6.3 z-scores and percentiles for a normal distribution

Be sure you have your own scientific calculator (or graphing calculator) to use during the exam. You may want to bring spare batteries.

2. How to study

Please see tips from first exam.

Practicing by solving problems is much more effective than reading over solutions. There are concept review questions in each set of exercises in the textbook. Going over homework and quiz correcting mistakes is also a good idea.

3. Exam content

The exam covers everything we have done, up to and including Section 6D. While the exam is cumulative, we will focus on what was not already tested. Here are some topics we emphasized since the last exam:

• statistics fundamentals: studies, population, sample, parameter, statistic, census, sampling methods, bias
• frequency tables: relative frequency, cumulative frequency
• displaying qualitative data: bar graph, Pareto chart, pie chart
• displaying quantitative data: histogram, line chart, time-series graph
• deceptive graphs
• measures of center: mean, median, mode
• distribution shapes: peaks, symmetry, left/right-skewed, outliers
• measures of variation: standard deviation, range, quartiles, five-number summary, boxplot
• normal distribution: 68-95-99.7 Rule, margin of error, confidence interval, percentile, z-score

As usual, please note that this document is not a contract. I may have inadvertently left something off that ends up on an exam question. Moreover, I will not be able to test all of this material given the time limitations of the exam. I will have to pick and choose some subset of it.
