Question
Calculate the z scores for each variable (education and memory)
(Round calculated results to the hundredth (2nd place to the right of the decimal) when result extends beyond that unless otherwise noted). 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. Q1a. Create a scatter plot between the two variabloc ucin
