    obtain a set of data containing at least two variables that can be used
    to establish the strength of a specified relationship

    . This relationship should relate to a
    clear (and meaningful) hypothesis. For these data you should
    • describe the source and quality of the data and how it was obtained
    • explain any process of selecting or sampling data and the implications that this
    may have
    • describe the nature of variation in the data and test whether it contains evidence
    of extreme values or high levels of skewness in its distribution of values
    • describe briefly the origins and meaning of the relationship that is specified
    • describe the form of the relationship based on charts
    • calculate the strength and nature of the specified relationship and test whether it
    is statistically significant using regression analysis
    • examine the manner in which individual values deviate from the overall
    relationship and discuss whether their pattern of deviation (if any) can be used
    to improve understanding of the relationship
    • write a brief interpretation of the meaning and implications of the results
