# Exam 1 Study Guide: Chapters 1-6

- Identify the context of the data. Context involves the who, what, where,
when, why, and how. For each variable (what), tell whether the variable is
categorical or quantitative and give the units for all quantitative variables.
Look at problems 2.2-21. Two parts.
- Categorical data. Be able to read a frequency table and answer questions
based on it. Be able to construct a pie chart or bar chart by hand. Look
at problems 3.5-13
- Contingency table. Be able to find percents, marginal distributions, conditional
distributions. Look at problems 3.14-31.
- Given a description of a situation, tell whether you would expect the distribution
to be uniform, unimodal, or bimodal. Tell if you expect it to be symmetric
or
skewed.
Look
at problems
4.3-4.
- Given a small set of data values, find the mean, median, mode,
variance, and standard deviation. Look at problems 5.3-10
- Given a set of summary statistics, construct a box plot. Write a sentence
or two describing the distribution of the data. Look at problems 5.23-26,
32
- Read and interpret an ogive. Look at problems 5.29-30
- Draw and label a figure that illustrates the Normal model and the 68-95-99.7
rule. Label the axis with the appropriate values based on the mean and standard
deviation for the model. Answer questions about what percent of the values
lie in certain regions based on the 68-95-99.7 rule. Find two standardized
scores based on the mean and standard deviation of the distribution. Look
at problems 6.11-12.
- A standard normal model is given. Find the amount of the area in
each region. Draw a figure and shade the region. You will need Table Z for
this problem. Five parts. Look at problems 6.19-20.
- Find the missing parameter from the Normal model. Look at problems 6.23-24.

## Notes

- Most of the problems are directly from the textbook or very similar to
problems from the textbook.
- You will need Table Z in appendix E for this test. This will probably be
provided for you, but you should bring your book just in case you need to
use it.. You do not get to use the rest of the text.
- You will need a scientific calculator.
- You will not need Minitab or Active Stats. Your computer screens should
be off during the exam.
