Warm Up Create a bar graph of the data.

1. Fill out your Table of Contents: Table of contents/ warm up Syllabus Frequency Table and Line Plot Notes Warm Up Create a bar graph of the data. Favorite rides at fair: Ferris wheel = 5, loop the loop = 4, merry-go-round = 3, bumper cars = 7, sit and spin = 9

2. Reading Math A group of four tally marks with a line through it means five. t llll = 5 llll llll = 10

3. A frequency table tells the number of times an event, category, or group occurs.

Which type of pattern do more students in Ms. Benn’s class have? Step 1: Make a column for each fingerprint pattern. Step 2: For each fingerprint, make a tally mark in the appropriate column MAKE SURE THERE IS A TITLE. Mode: Most students in Ms. Benn’s class have an arch fingerprint. l l l l l l l l l l l l l

8. Line Plots • Line plots are diagrams that organize data on a number line • If your data is numerical, one way to show it would be with a line plot

9. 5 6 7 8 9 10 11 12 13 14 15 16 Example 1: Students collected footballs for a project. The number of balls collected by the students is recorded in the table. Make a line plot of the data. Step 1: Draw a number line and title it. Step 2: For each football, use an x on the number line to represent how many were collected. x x x x x x x x x x x x # of footballs collected

10. Example 2: 5 6 7 8 9 10 11 12 13 14 15 16 Students collected aluminum cans for a project. The number of cans collected by the students is recorded in the table. Make a line plot of the data. Step 1: Draw a number line and title it Step 2: For each aluminum can, use an x on the number line to represent how many were collected. What is the mode? What is the median? What is the range? What is the mean? 5 5 5 5 7 7 11 11 14 14 14 15 x x x x x x x x x x x # of cans collected
