Studies of the Effectiveness of Graphic Materials
Morton S. Malter · The Journal of Educational Research · 1952
IN THE LAST twenty-five years, at least ten studies concerned with the relative effectiveness of various types of graphic materials have been reported. A number of the studies were conducted throughout a range of grades and include suggestions for the grade placement of graphs. Several of the studies involve pictorial types of graphs. All of them include one or more types of conventional graphs (bar, line and circle). The purpose of this article is to abstract several general conclusions from those reached in the individual studies.
