Final answer:
The statement on using data-based research strategies to create an inclusive vision for diverse learners is true, with the use of mixed-method approaches, CPAR, and life-course data collection.
Step-by-step explanation:
The statement 'Data-based research strategies are used to create a vision that takes into account the diversity of district learners' is true. Inclusive data-based research strategies such as mixed-method approaches, community-based participatory action research (CPAR), and the collection of data across the life-course are used to understand and address the varied needs of diverse learners within educational districts. By incorporating a variety of methodological approaches that take into consideration cultural, linguistic, and social issues in data collection, researchers can craft a vision for education that aims to promote equity and reduce disparities among students from different racial, ethnic, and socioeconomic backgrounds.
