This table represents a sample coding sheet from an episode of the “strange situation,” in which an infant (usually
about 1 year old) is observed playing in a room with two adults—the child’s mother and a stranger. Each of the
four coding categories is scored by the coder from 1 (the baby makes no effort to engage in the behavior) to 7 (the
baby makes a significant effort to engage in the behavior). More information about the meaning of the coding can
be found in Ainsworth, Blehar, Waters, and Wall (1978). [5]Source: Stangor, C. (2011). Research methods for the behavioral sciences (4th ed.). Mountain View, CA: Cengage.
The results of descriptive research projects are analyzed using descriptive statistics—numbers
that summarize the distribution of scores on a measured variable. Most variables have
distributions similar to that shown in Figure 2.5 "Height Distribution", where most of the scores
are located near the center of the distribution, and the distribution is symmetrical and bell-
shaped.A data distribution that is shaped like a bell is known as anormal distribution.
