摘要：People have to deal with problems on a daily basis.Problems mayappear both at the individual level and at the group level.Effective methods to deal with problems become essential.This paper questons ‘Does the number of people in a single group matter in effective problem solving? Previous studies have shown inconsistencies of results.This paper aims to find a cause-effect relationship between group size and the effectivity of problem solving wthin the group.There are two types of experimentalgroups with the total of 16 groups.The first eight consists of 4 people and the latter consists of 8 people within a group.One-tailed hypothesis stated that groups of 4 will perform better than groups of 8.Every group was given a same case to be solved.While the observed group dynamics differences existed, the results showed that the group of 4 is no better than the groups of 8 in terms of decision making effectivity.The results, will befurther discussed.
