Research question - A descriptive study to identify anemia in pregnancy is associated with low birth weight baby .
Hypothesis - The incidence of low birth weight babies in mothers who are anemic is higher than those who are not anemic .
Null hypothesis - There is no difference in the incidence of low birth weight in the mothers who are anemic and those who are not anemic .
Independent variable - Mothers anemia
Dependent variable - low birth weight of the baby
Alternative explanation ( potential confounds ) - these are the extraneous variables that have not been ruled out by a study design . In this research , besides mothers anemia premature birth of baby might be a potential cause for low birth weight of the baby .

Create a research question using the General Social Survey that can be answered by multiple regression. What is your research question? What is the null hypothesis for your question? What research design would align with this question? What dependent variable was used and how is it measured? What independent variable is used and how is it measured? What other variables were added to the multiple regression models as controls? What is the justification for adding the variables? If you found...

controlled variable, designing the procedure, level of treatment,
replication, the control. )
