Pizza Palace - Students will construct box plots independently. Students identify the mean, median, mode, and range of a set of data The Regression Line and Correlation - a lesson plan from Illuminations Scatterplots - explanation and several good examples from Canada's National Statistical Agency Scatterplots - a lesson plan from North Canton City Schools worksheet to use with the activity above Scatter Plot - includes examples of positive association, negative association, and no trend Scatter Plot - links to ten different examples are included with this Engineering Statistics Handbook entry Scatter Plot - the Wikipedia entry Scatter Plot and Line of Best Fit - four interactive applets to experiment with Scatter Plots - explanation, examples and several interactive practice activities Scatter Plots - from the Business Knowledge Center Scatter Plots - includes examples of perfect correlation, high correlation, and low correlation [This expired page is brought to you by the Internet archive, the Wayback Machine.] Scatter Plots - from Oswego City School District Regents Exam Prep Center [This expired page is brought to you by the Internet archive, the Wayback Machine.] Scatterplot with Overlaid Linear Prediction Plot - includes links to other plots on the right Spy Guys Interactive - Understanding and Interpreting Graphs - Lesson 10  Step-by-step Internet4Classrooms module - how to produce a scatter plot using Excel Use spreadsheets, graphing, and database programs to transform data into a table, graph, or diagram. 4.3 Bar Graph - Enter data to create a bar graph, then manipulate the graph's maximum and minimum values Charts, Tables, and Graphs: Data Interpretation - some things to remember when doing problems based on data interpretation Circle Graph - Enter data categories and the value of each category to create a circle graph (similar to "Pie Chart" but the user can define the data set) Collecting and Analyzing Data - multiple-choice quiz [5 questions] Data Interpretation Games - Numerous activities on using and interpreting data - Activities include bar, pie and line graphs, data collecting and much more Data Interpretation Practice Test - [25 questions] practice reading tables and a variety of charts; column, pie, and pictogram - answers at the end of the test  Data Picking - students collect data, enter tally marks or numbers and then select which graph is appropriate Fun and Sun Rent-a-Car - students use tables, graphs, linear functions to solve a real-world problem Graphing Skills - What's the point? find the point on Quadrant I of a coordinate plane Heads I Win - predict the likelihood of tossing heads or tails and graphs the results of coin tosses The Hot Tub - This is a fun activity where students tell the story behind a graph and relate slope to rate of change. Interpreting Circle (Pie) Graphs - students practice by answering eight questions about the graph Interpreting Column Graphs - students practice by answering ten questions about the graph Interpreting Data - survey a small group by clicking on each of the children, turn the tally marks into two types of graphs and then go back and take a different survey - Interpreting Data Quiz - after you finish the lesson above, take this quiz Interpreting Data - multiple-choice quiz from Gencoe math [5 questions] Interpreting Line Graphs - explore line graphs. Magic Bullets: Chemistry vs. Cancer - In this activity students will work with data about cancer deaths. The purpose of the activity is to give students some experience in reading and interpreting graphs. There is a worksheet associated with the data sets [these two expired pages are from the Internet Archive known as the Wayback Machine] Piece Of Pie - display data using a circle graph Push Ups - collect data to put on a line graph Spy Guys Interactive - Understanding and Interpreting Graphs - Lesson 10 Stem and Leaf Plots Lesson designed to introduce students to stem-and-leaf plots  Long Distance Airplanes - a stem-and-leaf plot lesson from Illuminations (rated 3rd-5th grade, but quite useful) Make a Stem-and-Leaf plot of the data you enter into the text area (ignore the warning about Internet Explorer, it works fine). Organizing Data in a Stem and Leaf Plot - a lesson plan from Annenberg CPB Making a Stem and Leaf Plot - An excellent interactive assignment can be found at the bottom of this page. Ordering a Stem and Leaf Plot - An excellent interactive assignment can be found at the bottom of this page. Grouping by Fives - An excellent interactive assignment can be found at the bottom of this page. Overview of Mean, Median, and Mode - presented as a discussion between student and mentor Overview of stem-and-leaf plot - a display that organizes data to show its shape and distribution [this expired page is from the Internet Archive known as the Wayback Machine] Stem-and-Leaf Plots - Their Construction and Use - an overview followed by several suggested assignments Stem and Leaf Plotter - an interactive applet that allow students to input data Stem-and-Leaf plots - from Purple Math Worksheet to accompany a "Stem-and-Leaf Plots" Lesson  Using Graphs to Understand Data - quiz from Glencoe math [5 multiple-choice questions] What Percentage of your Class is Right or Left Handed? - a data collection and analysis class experiment Distinguish between accuracy and precision. 4.4 Accuracy and Precision - from Wikipedia The Difference Between Accuracy and Precision - theoretical examples of accuracy and precition in a meteorological instrument Math Skills Review: Significant Figures - pointing out the relationship between accuracy of measurement and the number of significant figures to be reported Precision and Accuracy - good explanation, and diagram, from Math is Fun Precision and Accuracy - This Jr. High Math site points out the importance of using measurement devices that are as precise as possible. The Science of Measurement: Accuracy vs. Precision - "The dictionary definitions of these two words do not clearly make the distinction as it is used in the science of measurement." Analyze alternate methods for representing data graphically and interpret the results of an experiment. 4.5 � State a conclusion in terms of the relationship between two or more variables. 4.6 � Examine trends in data in order to answer questions. 4.7 � Analyze experimental results and identify the nature and sources of experimental error. 4.8 � Apply knowledge and data-interpretation skills to support a conclusion. 4.9 � Suggest alternative explanations for the same observations. 4.10 � Explain whether the data supports or contradicts the original hypothesis. 4.11 � Develop alternative hypotheses. 4.12 � Formulate and revise scientific explanations and models using logic and evidence. 4.13 � Develop a logical argument about cause-and-effect relationships in an experiment. 4.14 � Internet4classrooms is a collaborative effort by Susan Brooks and Bill Byles.
