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 Another version of the above information 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."
