Project CRISS Reading Program and Grade 9 Reading Achievement in Rural High Schools
Analysis plan
The analysis of the reading achievement student outcome will have two components. Outcome data will first be subjected to a series of descriptive analyses to examine the general characteristics of the data and determine whether they meet typical assumptions for more sophisticated analyses. Outcome data will then be subjected to more sophisticated statistical analysis to infer whether there are statistically significant program effects on students, making appropriate corrections for the nesting of students in schools (the unit of random assignment). The estimation of an effect size will be expressed in standard deviation units so that Project CRISS can be compared with similar reading comprehension programs that have undergone rigorous scientific study.
