Question

1) A study was performed examining epidurals as one factor that might inhibit successful breastfeeding of newborn babies. Suppose a broader study included several additional issues, including whether the mother drank alcohol, whether this was a first child, and whether the parents occasionally supplementing breastfeeding with bottled formula. Why would it not be appropriate to use chi - square methods on the table with yes/no columns for each potential factor?

   A.) These factors would not be mutually exclusive. There would be yes or no responses for every baby for each.
   B.) It is appropriate to use a chi - squared method
   C.) These factors are not counts. Some are quantitative which are not appropriate for a chi - sqaured method
   D.) There are too many factors to use a chi - squared method
  E.) None of the above

Explanation / Answer

Answer:

1) A study was performed examining epidurals as one factor that might inhibit successful breastfeeding of newborn babies. Suppose a broader study included several additional issues, including whether the mother drank alcohol, whether this was a first child, and whether the parents occasionally supplementing breastfeeding with bottled formula. Why would it not be appropriate to use chi - square methods on the table with yes/no columns for each potential factor?

   Answer: A.) These factors would not be mutually exclusive. There would be yes or no responses for every baby for each.
   B.) It is appropriate to use a chi - squared method
   C.) These factors are not counts. Some are quantitative which are not appropriate for a chi - sqaured method
   D.) There are too many factors to use a chi - squared method
  E.) None of the above

For applying chi square method, we require two categorical variables with mutually exclusive responses.
