An investigator wants to study the association between maternal intake of iron supplements (Yes / No) and birth weights (in grams) of newborn babies. He collected relevant data from 100 pregnant women and their newborns. Which test of significance will be applicable in this case? (AIIMS Nov 2010)
|A||Student t test|
|B||Chi Square test|
|C||Paired t test|
There are two groups of women and the weight in grams are to be compared that means the data is quantitative and the number of observations are 100, so an unpaired T test ( Parametric test) would be best in this case.
