Scott analyzed language proficiency scores for students who were learning Chinese. Students were given 5, 10, or 20 hours of training per week, and after four weeks they completed a language test (higher scores indicate better proficiency). Below is the SPSS printout from a oneway analysis of variance. Descriptives Language Score 95% Confidence Interval for Mean Mean Std. Deviation Std.
