A group of 44 student volunteers have agreed to try a new drug which affects iron absorption from the gut. The volunteers were split into two equal groups (group A and B) matched for age and gender. One group took the drug and one group took the placebo (sugar pill which looked identical to the drug). Each group then had their Haemoglobin (Hb) levels measured from finger prick blood. On the provided Excel sheet, you have been given the Hb in the white cells measured from the two groups. The yellow cells show the descriptive stats for the data.
Your aim is to investigate whether there is any difference in the mean Hb between the two groups.
You are required to complete a laboratory report based on the above study which is linked to the practical you did ‘Investigation of blood’.
