Lots of research has taken and is occurring on the basis for dyslexia and it appears that the brain of people that have dyslexia functions differently to those without. When surveying people, exploratory research studies would not attempt to acquire a representative sample, but instead, attempt to interview those people who are knowledgeable and who may be able to supply insight concerning the relationship among variables.
Correlational studies identify factors resulting in a specific circumstance. There are lots of studies, personal anecdotes and a few statistics obtainable for different techniques of multisensory treatment of dyslexia. Exploratory research is distinguished by its flexibility. Descriptive research is also called Statistical Research. There's various research which supports this system, while this is limited, but I have not found any research that is negative in regards to the multisensory strategy.
