Effective Data Visualization Techniques for Classroom Scenarios

This guide offers insights into selecting the most suitable graph types for various data representations in a classroom setting. It discusses the effectiveness of line graphs for showing relationships between numerical values, box-and-whisker plots for median and score analyses, circle graphs for budget fractions, and bar graphs for comparing groups. The guide enhances understanding of independent and dependent variables, differentiating continuous and discrete data, and choosing appropriate graph types. It also prepares students for assessments on data interpretation and visualization.

  1. 8.3 Display Data • Pgs. 395-398 Example 1 Example 2 # 1, 2, 3, 4, 5, 6

  2. Choose a Suitable Graph • What would be the most appropriate way to display this data, a bar graph or a line graph?

  3. A LINE GRAPH would be the best way to display this data because it shows the relationship between two numerical values!

  4. Select the most appropriate method for each situation: • How the median test score relates to the minimum and maximum scores for a class of data • : Box and Whisker Plot • What fraction of a family’s budget is spent on food • : Circle Graph • Compare the populations of the provinces of Atlantic Canada • : Bar Graph • Show the number of people attending a movie grouped by age intervals • : Histogram

  5. What is the independent variable? What is the dependent variable? Is this data continuous or discrete? What type of graph would be best to display this data?

  6. What is the independent variable? What is the dependent variable? Is this data continuous or discrete? What type of graph would be best to display this data?

  7. Viewers rating results for a new television program are displayed as a bar graph and as a circle graph. E means excellent, VG means very good, G means good, F means fair, P means poor and VP means very poor • Which graph can be used to answer the following: • How many viewers were surveyed? • Which rating had the most response? • Describe the relationship between excellent responses and very good responses. • How many viewers rated the program as poor? • What percent of viewers rated the program as good or better?

  8. YOUR TURN …. • Pg. 398 #6 • Pg. 399 #10 (to be handed in) • Pg. 404-406 # 1, 3, 7, 9 • Pg. 406 #9 (to be handed in) • ** TEST ON FRIDAY OCTOBER 8TH • PRACTICE AND REVIEW • Pg 408-411 # 1, 2, 4, 5, 6, 7, 8, 12, 13 • Pg 412 – 415 # 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 • *** DO NOT DO ANY PARTS THAT SAY “DETERMINE THE EQUATION OF THE LINE”
