For this week’s assignment, utilize the following
Excel data, which contains B.M.I., F.B.S., gender, and clinic
information for a group of children ages 10-14, to complete items four and five

• Correlate F.B.S. with B.M.I.  What correlation
coefficient will you use?  Why?  Report the correlation
coefficient and explain whether this is a statistically significant
correlation.  Explain what it means for two variables to have a
statistically significant correlation.  The steps for running a
correlation in Excel are described in Section 8.4 of your course text.

• Run a simple linear regression predicting F.B.S. from
B.M.I.  Report your results.  Does F.B.S. increase or decrease
with B.M.I.?  What components of the output do you read and interpret
to answer this question?  Write the regression equation and include
it in your paper.  The steps for running a linear regression in Excel
are described in Section 9.3 of your course text.
