NC Standard Course of Study Intermediate grades 3-5: Data are described and compared using median, mode, and range. R. Alnizami
Common Core Standards On the other hand, the common core standards propose that the idea of center is introduced for the first time at the 6th grade. But… R. Alnizami
Common Core Standards: 5th grade: measurement & data 5.MD.2. Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8). Use operations on fractions for this grade to solve problems involving information presented in line plots. For example, given different measurements of liquid in identical beakers, find the amount of liquid each beaker would contain if the total amount in all the beakers were redistributed equally. The mean R. Alnizami
Research "Curriculum documents around the world recommend that students develop some understanding of mean, median, and mode before entering secondary school" (Groth & Bergner, 2006, p. 38). R. Alnizami
MoreResearch • Similarly, Lappanet al. (1988) presume that the concept of average is introduced as early as the fourth grade. • Results of a study on elementary and middle school students indicate that when statistical concepts are introduced at the elementary level, later students' understanding of and attitudes towards statistics can be positively affected ( Mills, 2004).
