The data set for this question set (Tab Q1 in the Excel data file) comes from a research project that
tracks the elderly residents in a community to monitor their cognitive function and general health.
Based on the literature, education is considered a protective factor against dementia, and memory
decline is usually the first sign of dementia. So, the researchers would like to know whether education
level (measured in number of years of formal schooling) is correlated with memory function (a
standardized memory test score) in their sample of elderly residents.
