Are you confused by terms that educators use? The ASCD Lexicon of Learning might be what you need.
CT4ME has identified resources related to each benchmark of the Ohio Mathematics Academic Content Standards that students should have mastered by the end of the grades 8-10 program.
Identify the benchmark (A-K) for review in Data Analysis and Probability. Below each benchmark, you will find Web resources for reviewing the concept and practice problems.
Students should be able to review on their own using these resources. If you are not an Ohio educator, these resources can still benefit your test prep efforts, as benchmarks in other states are similarly stated.
Download the Test Prep Strand Booklet
Data Analysis and Probability (pdf) This test prep booklet (about 200 KB) is designed to help you monitor your progress toward mastery of each benchmark in this strand. You can print the entire booklet, or just those pages for benchmarks you need to work on. Write notes in the booklet next to each resource you use in your review.
If
needed, download
Adobe Acrobat Reader, free software for viewing and printing PDF files.
You
might need to download Java, a
free plug-in from Sun Microsystems to interact with virtual manipulatives on
this page.

strand resources:

NOTE: As a general resource for all Data Analysis and Probability benchmarks, students might consult the following resource:
Algebra from Oswego City School District (NY) Regents Exam Prep Center. Each sub-section includes lessons and interactive practice exercises. The probability and statistics strand has two sections: Working with Data and Probability.
A. Create, interpret and use graphical displays and statistical measures to describe data; e.g., box-and-whisker plots, histograms, scatterplots, measures of center and variability.
NOTE: Each type of graph has its advantages and disadvantages.
Line graphs and histograms are only used with continuous data, which means that theoretically all values are possible (no gaps) in an interval (between any two it is possible to get another). Examples include height, weight, time to complete your homework, and time to complete a trip.
Bar graphs and circle graphs are only used with discrete data, which means that only certain values (gaps) are possible. Examples typically include counting, as in the number of students in a class, the number of crimes reported to the police, or the number of tickets sold to a game.
Scatter plots are used for experimental data to determine if there is a relationship between the variables studied.
When creating graphs, note the following 10 common errors, provided by CanTeach (CA):
