- Vocabulary: A definition is given. Match it to the term best defined. Twenty terms. Not all terms are used. Know class marks, class boundaries, class limits, continuous data, discrete data, inter-quartile range, mean, median, midrange, mode, non-sampling error, parameter, population, qualitative data, quantitative data, range, sample, sampling error, skewed distribution, standard deviation, statistic, symmetric distribution, variance, variation.
- A chart and corresponding explanation are given. Know the types of sampling, self-selected surveys, sample size, how to convert a frequency to a percent, and why a large sample isn't necessarily a good thing.
- Identify each variable as discrete or continuous. Five parts.
- You will be given the mean, median, range, standard deviation, and variance for a sample. A transformation is then applied to the data from the sample, and you need to indicate what the new values of the statistics are. Three parts. This is from the lab.
- Know which measures of central tendency and dispersion are affected by extreme values, resistant to change, use all the data values, always exist, must be positive, and must be one of the data values.
- Determine which type of sampling (random, systematic, stratified, cluster, convenience) is used. Ten parts.
- Portions of a press release are given. Read the article and answer questions based on it. Know the types of sampling, how to apply a margin of error to a sample, and list types of non-sampling error listed in the article.
- Know what the five numbers in the five number summary represent and be able to create a box plot from a five number summary.
- Portions of a press release are given. Read the article and explain why this is a bad use of statistics.
- Portions of an article are given. Read the article and answer questions based on it. Find the questionable use of statistics in the article and know the difference between discrete and continuous random variables.
- Given a stem and leaf plot, find the range, median, and another percentile. Pay attention to stem and leaf plots where there are multiple digit leaves (look at problem 2.3.14 or the video).
- Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate. Nine parts.

- None of the problems are directly from the text.
- There is a take-home portion of the exam due on the day of the in-class exam. The take-home portion of the exam is worth 15 points and is to be done with Minitab and Statdisk.
- References to data obtained from the Internet are given on the test. They may be ignored for purposes of the exam, but they may provide interesting reading later.
- Be sure to bring your calculator.
