Question
Below is a table of calls to a Poison center in Manhattan Kansas for exposures to
disinfectants.
A) Calculate the Row and column totals, and do usual Chisquare analysis to see if there is an
association between year and age for the poisonings at the .05 level
Age 2018 2019 2020
0–5 76 68 81
6–19 18 17 29
20–59 27 28 45
≥60 93 85 220
B) Are there any really unusual deviations from expected values.
C) Within each age group, 0-5, 6-59 (put two 6-19 and 20-59 together to get enough data), and 60
and up, run the Poisson difference tests we discussed to see if there are any interesting
differences across the years. There will be 3 comparisons pre age group times 3 groups for 9
tests, Use FDR, not independent at the Q value of .1 to evaluate.
D) What about the approach in C means some of the P values are not independent?
