a personal process, one which nobody else can do for you.
Simply take the time to review what you have done.

Draw a line graph. [14.1]
Draw a stem-and-leaf plot. [14.1]
Draw a circle graph. [14.1]
Draw a pictograph. [14.1]
Read and interpret relationships presented in graphical
form. [14.1]
Recognize misuses of graphs. [14.1]
Find the mean, median, and mode for a set of data. [14.2]
Decide on an appropriate measure of central tendency. [14.2]
Find the range, standard deviation, and variance for a set
of data. [14.2]
Find a cumulative distribution. [14.3]
Interpret information given in table form. [14.3]
Find the expected numbers for ranges of a normally distributed
set of data. [14.3]
Determine the probability of falling within a certain range
of a normally distributed set of data. [14.3]
Find and use z-scores. [14.3]
Know the meanings associated with a normal curve. [14.3]
Draw a scatter diagram for a data set. [14.4]
Decide whether there is a significant linear correlation
between two given variables. [14.4]
Find a regression line for a data set.[14.4]
Discuss the type of correlation for a given data set. [14.4]
Determine whether there is a significant linear correlation,
given the number of items and the correlation coefficient.
[14.4]
Find the correlation coefficient for a given set of data.
[14.4]
Choose an appropriate procedure for selecting an unbiased
sample. [14.4]
Classify Type I and Type II errors. [14.5]
Make an inference about a population by taking a sample.
[14.5]
Once again, see if you can verbalize (to yourself) how
to do each of the listed types of problems. Work all of
Chapter 14 Review Questions (whether they are assigned
or not).
Work through all of the problems before looking at the
answers, and then correct each of the problems. The entire
solution is shown in the answer section at the back of the
text. If you worked the problem correctly, move on to the
next problem, but if you did not work it correctly (or you
did not know what to do), look back in the chapter to study
the procedure, or ask your instructor. Finally, go back
over the homework problems you have been assigned. If you
worked a problem correctly, move on the next problem, but
if you missed it on your homework, then you should look
back in the book or talk to your instructor about how to
work the problem. If you follow these steps, you should
be successful with your review of this chapter.
We give all of the answers to the Chapter Review questions
(not just the odd-numbered questions), so be sure to check
your work with the answers as you prepare for an examination.
