Mean, Median, Mode and Range

Day 3Objective: Students will find their heights then find how they compare to the class.Students will make analyze a box and whiskers plot and find mean median mode andrange of the class data.Standards:NCTM Standards: Number and Operations, Data Analysis, MeasurementNew York State Key Ideas: 5A, 5DMaterials:Tape measureCalculatorStudent WorksheetOpening: Students will be asked to write down some generalizations about what theybelieve to be true about the class’ height.Main: Students will work in pairs and measure their heights in centimeters. Studentswill then record the heights on the chart taped to the front board. Also students will inputtheir data into a list on the TI- 73 calculator. Chart is separated into males and females.Once everyone is finished the class will have a discussion about the tallest, shortestheight. Are there any heights that do not make sense? Students will work in pairs to findthe mean, median mode and range of the entire class data, male data and female data.Closing: We will then see if there are any patterns, or is the data what they expected todiscover. From the lists on the calculator, make a box and whiskers plot of the males andthe females. See the data from the box and whiskers plot match what the students foundto be true.Homework: Unit ProjectAssessment: As students are working walk around and make sure they are on task.Teacher’s Notes: Make sure students understand that the tape measure is not as tall asthe students and they need to add an amount to it. Having two calculators one for thefemales and one for the males to input data, may be useful not to confuse the data. Thentransfer the lists to one calculator.9
