  1. Algebra 1Predicting Patterns & Examining Experiments Unit 8: Change at the Center Section 3: Time for Frequency

  2. Rock, Paper, Scissors, Bar?

  3. Bar Graphs vs. Line Graphs

  4. PREVIOUSLY: Which powerball is most likely?

  5. PREVIOUSLY: Which powerball is most likely? We use bar graphs to show frequency of different values.

  6. PREVIOUSLY: What is the average price of a gallon of gasoline over the last 20 years? Average (mean): The average price is $1.54 average = $1.54

  7. PREVIOUSLY: What is the average price of a gallon of gasoline over the last 20 years? Average (mean): The average price is $1.54 We use line graphs to show a pattern over time. average = $1.54

  8. Student Quiz Scores If I wanted to display the quiz scores of a class of students would I use a bar or a line graph?

  9. Student Quiz Scores If I wanted to display the quiz scores of a class of students would I use a bar or a line graph? BAR

  10. Student Quiz Scores If I wanted to display the quiz scores of a class of students would I use a bar or a line graph? BAR

  11. Student Quiz Scores If I wanted to display all quiz scores of one student would I use a bar or a line graph?

  12. Student Quiz Scores If I wanted to display all quiz scores of one student would I use a bar or a line graph? LINE

  13. Top Mascots How would you display the top 10 (most frequent) mascots for US colleges and universities?

  14. Top Mascots How would you display the top 10 (most frequent) mascots for US colleges and universities?

  15. Top Mascots How would you display the top 10 (most frequent) mascots for US colleges and universities? How could we be more creative with our bar graph?

  16. Top Mascots How would you display the top 10 (most frequent) mascots for US colleges and universities?

  17. Top Mascots How would you display the top 10 (most frequent) mascots for US colleges and universities? Technology has several options for presentations, but they are superficial changes (colors, basic shapes). We should examine the design of our presentation, once the accuracy is finalized.

  18. Top Mascots How would you display the top 10 (most frequent) mascots for US colleges and universities? Ideally, we could have a tall bulldog (the most frequent mascot) and a shorter pioneer (the least frequent), or some other more appropriate graphic.

  28. Homework Create four graphs: two line and two bar graphs. Find data (research online or locally) and create graphs that represent the data. Consider the well-designed examples. How can you best represent the data graphically? What color scheme and graphics would best represent your data? Have fun with the assignment.
