Child development specialists widely believe that diverse recreational activities can improve the social and emotional conduct of children. The article “Influence of Physical Activity on the Social and Emotional Behavior of Children Aged 2–5 Years” (Cuban J. of Gen. Integr. Med. 2016) reported a study of 25 young children diagnosed with social and emotional behavior problems. The children participated in a physical activity regimen for one year, and each child was measured for negative social behavior indicators (tantrums, crying, etc.) both before and after the regimen. Lower scores indicate improvement; the children’s changes in score (post minus pre) are summarized below. 

Use the sign test to determine whether the data indicates a statistically significant improvement in scores at the α = .05 level.
