Top of Form 1 Marks: 6 Please match the following terms with the appropriate description. The mean of the sum of squares. Range of scores in a distribution that includes 25% of the cases. The average distance scores fall from the mean. Based on a sample statistic, a range of scores likely to contain the population parameter. Distribution of sample statistics based on infinite sampling. The average distance a sample statistic can be expected to fall from its population value. Question2 Marks: 1 For this problem and other problems in this exam, rely on the following information. Szalacha, Erkut, Coll, Alarcon, Fields, and Ceder in 2003 investigated the research hypothesis that Puerto Rican children in the US who report or perceive discrimination will have more mental health problems and higher school-related stress than Puerto Rican children who do not perceive discrimination. The researchers presented the table below with scores on the Reynolds Child Depression Scale (RCDS).
