  • Abstract:

    The scatter diagram below shows one potential influential observation, namely Alaska, which is an outlier in terms of spending per pupil. In addition, the question can be raised whether the level and slope of an appropriate regression line would be the same for the three regions of the country. Students should investigate these questions by examination of residuals and execution of appropriate regres- sions. The steps taken should be reported and the final regression analyzed.
