Short case-studies may be used; however for a more profound understanding of these conditions, a deeper look into the cases is necessary. Written by four professors, each case outlines the events leading up to the patient initiating therapy, the patient’s family and social history, the treatment, the discussion of the condition and etiological considerations.These in depth cases make excellent options for psychology students looking for some data to include in essays and presentations.
In this case the median or the mode is a better indicator of central tendency than is the mean. You can see from Figure 3.6 that the mode for the family income variable is $93,000 (it occurs four times).
In addition to summarizing the central tendency of a distribution, descriptive statistics convey information about how the scores of the variable are spread around the central tendency.
Each of the four coding categories is scored by the coder from 1 (the baby makes no effort to engage in the behaviour) to 7 (the baby makes a significant effort to engage in the behaviour).
More information about the meaning of the coding can be found in Ainsworth, Blehar, Waters, and Wall (1978). The distribution of the heights of the students in a class will form a normal distribution.
