  • The Correlation Coefficient

    table. x 2 4 7 3 5 1 y 10 5 2 9 4 10 To find the correlation coefficient it is most efficient to first find the summary statistics. Your calculator may have functions to help. They are The correlation coefficient is then calculated from r= This means...

  • Permutations

    Permutations is that part of statistics involving arrangements of objects, some of which fall in the same group and some of which fall in different groups. Each object is distinct from all the other objects, so we can tell each one apart, and if two...
