Step 1&amp;nbsp;Given,The difference between the pain felt by kids with sickle cell disease (SCD) in inpatient and outpatient settings was investigated. The primary outcome of interest was pain intensity (visual analog scale), although potential confounders included age and physical activity.Step 2&amp;nbsp;It will be more reasonable to do a two sample t-test.The patient category (inpatient or outpatient) acts as an independent variable in this situation, making the two samples independent.We assume that the population is Normal with the same variance because the VAS is a quantitative (continuous data) measurement of pain intensity.Age and physical activity are two potential confounders, therefore we must account for these as well as maybe define inclusion and exclusion criteria that restrict the groups in order to provide data that is free of confounders.Bar charts are suitable for visually describing the data.
