    Question

    An educationalist wants to investigate whether prior knowledge of body parts (PREBODY) depends on residential environment (site) and general development (PEABODY). For residential environment, four categories are distinguished:

    Site 1 = city advantaged Site 2 = suburb Site 3 = city disadvantaged Site 4 = village

    Data from the Sesame Street survey was used. The output of the analysis (parameter estimates) is given.

    Which of the following conclusions is the only one correct?


    1. FALSE: If PEABODY rises one point then the predicted score on PREBODY changes 11.9 points.
    2. FALSE: The difference between the city favored category and the intercept of the reference category is 11.9 points.
    3. FALSE: The average prediction error for the four categories of the variable SITE is equal to 11.9 points.
    4. TRUE: The intercept of the comparison of reference group is equal to 11.9 points.
