Box Plots Notes © copyright 2014 – all rights reserved www.cpalms.org

Learning Objectives Students will be able to: 1) Construct a box plot given a set of data.   2) Describe the elements within a box plot. 3) Analyze and interpret a box plot including   The meaning of upper and lower quartile. Explain the meaning of the median. The meaning of upper and lower extremes. Identifying if there are any outliers. Teacher will have a different student read each objective aloud.

What you should already know!!! How to list numbers from least to greatest. How to draw an evenly portioned number line that is appropriate to the given data set. How to accurately create a dot plot. How to calculate the range of the data. How to find of mean and median. Teacher reads what the students should already know.

Example Ms. Alexander was on the track team in high school. The following numbers represent the time(in minutes) it took her to complete the 200 meter dash race at each competition. 1.96, 3.89, 4.76, 1.83, 2.11, 2.09, 1.74 Teacher reads this out loud to class.

Organize the data from least to greatest. 2) Find the median of the data set. 3) Identify the lower and upper extremes. 4) Identify the lower and upper quartile. Teacher will show students step-by-step how to solve each question on this slide. As the teacher explains each number, the vocabulary will also be defined. Students will take notes as the teacher is going through the process. Students will listen to the teacher, watch what is being written, and formulate possible questions about what is being taught.

5) Calculate the interquartile range 5) Calculate the interquartile range. 6) Determine if there are any outliers. 7) Construct the box plot. 8) What is the shortest time Ms. Alexander ran? 9) What percent of the data is greater than the median? 10) What percent of the data is contained in the lower quartile? Teacher will show students step-by-step how to solve each question on this slide. As the teacher explains each number, the vocabulary will also be defined. Students will take notes as the teacher is going through the process. Students will listen to the teacher, watch what is being written, and formulate possible questions about what is being taught.

Let’s Practice  Record the length of time it takes you to get ready in the morning before school. Students will have previously written down their time from the previous class on a post-it note. Teacher should have the data displayed on a excel file in random order for students to write down.

Organize the data from least to greatest. 2) Find the median of the data set. 3) Identify the lower and upper extremes. 4) Identify the lower and upper quartile. Each student that comes to the board to answer a question will be required to write the correct answer and explain how they arrive at their answer.

5) Calculate the interquartile range 5) Calculate the interquartile range. 6) Determine if there are any outliers. 7) Construct the box plot. 8) What is the fastest time someone takes to get ready? 9) What percent of the data falls in the lower quartile? 10) How many people take less than an hour to get ready? What percent of the sample is it? Each student that comes to the board to answer a question will be required to write the correct answer and explain how they arrive at their answer.
