  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.

  4. whorl loop whorl loop arch arch loop whorl loop arch whorl arch arch whorl arch loop Making a Frequency Table Students in Ms. Benn’s class recorded their fingerprint patterns. Which type of pattern do most students in Ms. Benn’s class have? Make a tally table to organize the data.

  5. whorl loop whorl loop arch arch loop whorl loop arch whorl arch arch whorl arch loop Additional Example 1 Continued Students in Ms. Benn’s class recorded their fingerprint patterns. 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

Which type of pattern do more students in Mrs. Lieu’s class have? Make a frequency table with tally marks to organize the data.

  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
