Connecting Algebra 1 to Advanced Placement* Mathematics A Resource and Strategy Guide Use Dotplots (Line Plots) to Determine Mean, Median, Mode, and Range Updated: 04/13/09 Objective: Students will use a dotplot (a line plot) to determine mean, median, mode and range. Connections to Previous Learning: Students should be able to determine the mean, median, mode, and range for a set of data. Connections to AP*: AP Statistics Topic: Distributions – Measures of Center, Shape, and Variability Materials: Student Activity page, a sticky note for each student, butcher paper or chalk/white board Teacher Notes: Often one of the responsibilities of a Pre-AP Algebra I teacher is to search for students who have been “missed” in order to open the gate to a wider number of students. This lesson, along with “Analyzing Mean, Median, Mode, and Range”, is designed to provide meaningful statistical connections during the first few days of algebra before moving on to more typical algebra activities. While students should be able to determine measures of central tendency of data, few have used a dotplot (line plot) to aid in determining that information. The first activity in this lesson is teacher directed and requires a sticky note for each student. Have the student write the number of letters in her/his last (or first) name. Have the chalk board or a piece of butcher paper pre-marked with numbers from 3 to 12 as the number line for a dotplot. Note: A dotplot is frequently referred to as a line plot; however, the term used AP* Statistics is always dotplot. Leave enough space between marks for the width of the sticky plus a little. Have students come up one group (or row) at a time to place their sticky notes in the correct column. Take some time here to let them review the arithmetic necessary to find each measure. This activity can be done very quickly, but resist tha
